You won’t believe the cost of a spare car key…

How much does it cost to replace your car key? Let’s just say that for a modern car, you’re not looking in the tens of pounds. Have you ever had to buy a replacement car key, and did you feel ripped off?

A few weeks ago, I went to get some spare house keys cut. It cost me £14.50 for two cylinder keys and a mortice key.

Although I was expecting to pay a little less, on reflection, I felt that was a pretty fair deal – after all, security is worth paying for, right?

However, I’m glad I didn’t need to buy a spare key for my car.

The expense of car keys

Of the hundreds of Which? members who contact us every month, one query caught my eye. The member described the cost of getting a new car key as ‘exorbitant’ – and suggested we investigate.

I quickly got on the phone to some of the car dealers in my area. I asked them to quote the cost of a year-old version of their most popular medium or large car.

The average price of a key from Audi, Mercedes, BMW, Ford, Vauxhall and Hyundai? £174!

Every single manufacturer I’ve spoken to so far charges well over £100 for a replacement key. Ford was the cheapest at £130 (admittedly this isn’t for the latest Focus), while Audi and Mercedes both asked for a whacking £228.

Are car keys a rip-off?

I have to say, I certainly like the convenience of remote central locking. But the latest must-have feature (one which is being promoted by Ford in the current Fiesta adverts) is “keyless entry”. This requires even more sophisticated chips and transponders inside the key – ultimately pushing the price up.

I rang another Ford dealer and found that a keyless fob for a new Fiesta (the UK’s biggest-selling car) costs £193, while a normal key is ‘just’ £135.

Car keys perform what is, in essence, a very simple job. They let you into your car and start it. Do they really need to be quite so complicated – and expensive? Or do you think the convenience of a remote locking or keyless system is worth the extra cost?

You say how much outlay for cost of business etc and how long lo recoup the outlay, I had a business and I never ripped off the customers like this.
Now imagine you brought a a large fast food franchise ,the outlay is in the 100s of thousand, do they charge you £10 for fries-£15for a coke and £30 for a burger?

They have staff and overheads and running costs
The con starts at the top and runs down like a pyramid sales scam, although locksmiths are not that bad as main dealers.
In this country we just talk but no action- lets look to France if we want our voices heard.

You will find most auto locksmiths do not rip anyone off! If you don’t know what a locksmith get there items at at trade price then you shouldn’t comment really!
Has said before example Renault key car for auto locksmith at trade between £60-80
programming it into the vehcle around £15 reason being autolocksmiths programming machine costs betwwen £2000-8000 and some use tokens around £15 a vehicle.
cutting of the emergency blade £10 . auto locksmith key cutting machine to code3 cost anything from £2500-£6000.
Picks to enter vehicle and decode £80
Van fuel cost average £10 per job
van insurance ££
wear and tear of vehicle£££
liability insurance £150-400
auto locksmith wage
Now tell me how a auto locksmith rips customers off with that outlay?

And for costs of fries ect you would normally get 50 plus customers a day, an auto locksmith may only get 1 job a day, its not a 9-5 job!

As the previous reply stated to compare a burger bar to a locksmith isn’t a fair one, obviously the higher the volume of customers the cheaper the service or products becomes, as a manager of an establised locksmith i am all to much aware of the very high outlay on diagnostic equipment, high tech key cutting equipment, well trained qualified staff and good quality stock, we also have to invest
on regular software updates and purchase various licences to enable us to reproduce vehicle transponder keys and remote keys, our last investment was around £17,000.00 on diagnostic
software alone, so don’t be to quick to judge as i can assure anyone that reproducing modern vehicle keys involves time, effort, and can be money pit, we forecast we will not actually draw a profit for three years based on our initial investment, then there is the on going cost of software updates and training but as this is part of the general service we supply we continue to provide this service to our customers, not whinging just trying to give another perspective,

Very quick to defend charges and costs which every business face what makes your such business different?
Forget it my post will not make a difference so you carry on…. Happy 2014 matey

As a follow on to my previous post it may be worth mentioning that the entire concept of purchasing a burger and a remote key is completely different, when you purchase a burger ( or any fast food for that matter ) the reasons for that purchase are generally because it tastes good, its quite cheap, but more to the point you WANT IT, therefore you don’t mind paying however in my 28 years experience in the lock trade i can say without doubt we are classed as a ‘grudge purchase’, you do not WANT our service however you may NEED it so people mostly resent parting with there cash for our services and products.

I believe that rather than complaining about the cost of a spare key we should be asking why manufacturers don’t provide enough keys in the first place.

My new VW Golf came with only two keys (the previous one had come with two and an emergency key with the transponder but no remote control function. I suppose I should feel luckier than a couple whose new car was supplied with two keys but only one with a remote control function.

A couple will need two keys, or three if a son or daughter uses the car, and it is commonsense to keep a spare key. Therefore manufacturers should provide four keys with a new car. Unlike cutting and programming a new key, which is expensive, providing an extra couple of keys would add very little to the cost of a new vehicle and could save a great deal of hassle.

Come on manufacturers. Provide four keys with each new car.

You are really good and fast but the best thing is quality and prices, thank you for keep doing that great job. GOD Bless.

The modern key does so much more than open the car and start it.
Well worth the price, most need to be computer matched to your car, the price usually includes that work and takes an odd 15 mins or so depending on make.

You are right about what the key does, but the cost of spares could be avoided if car manufacturers provide at least four keys with a new car. The cost will be small if they are all programmed at the same time.

Unfortunately that’s a marketing ploy from all main dealerships, profit margins on the sale of vehicle’s has eroded, in most case’s it can be as low as 8% therefore all dealership’s will use whichever strategy they have control over
to draw a profit from the servicing aspect, morally it’s questionable but as far as generating income
goes it’s fairly simple, why supply additional keys for nothing when they can charge £££££ for spares ?

These keys are not expensive to make, They are a money making scam and we are soft enough to pay these prices. A modern mobile phone is infinitely more complicated yet can be purchased for a fraction of the price. I just bought a Android smart phone sim free without contract for under £80.

I’m uniquely unqualified for this thread, but that’s not gonna slow me down!
I’ve never bought a new car and my current is 17 (get yer mind out of the gutter, I’m still talking about my car).
Now I’ve got your attention, can I ask three questions?

Can you buy extra keys with a new car?

Can the dealer work on your car without having your key?

Is there still such a thing as a “master key”. I believe Renault used to supply one.

MIKE says:
2 December 2014

If you buy a used car from a reputable dealer they will almost certainly be in a position to provide a spare key, usually via a local auto -lock specialist or locksmith who can supply and programme transponder keys, however there are a couple of issue’s that come into play, the dealer is not legally bound to supply a second key, the cost of supplying a second remote key can still cost the dealer over £200,00 trade therefore does the profit on the sale of the car justify the outlay?, again if the dealer is a reputable one they will usually compromise and pay for a non-remote key as these can be supplied trade from as little as £25, a non-remote key will still be programmed to start the vehicle.
Master keys were available on older Ford, Fiat and Toyota models ( circa 1997-2003 ), the master key allowed the owner to programme a new key ( with transponder chip ) themselves, that facility has not existed in the UK for around ten years. There is sometimes a misconception from the public regarding the term ‘ master key ‘ whether for a vehicle lock or front door lock but that is a separate discussion,however as a trading locksmith i retain in excess of 100 master keys all individually produced to operate under a unique system, the is no such item as a ‘ generic master key ‘. And no there is no Renault master key.

Any garage will require a working key as the key ‘ opens’ the ECU which permits access to the vehicles computers, almost all modern vehicles require diagnostic servicing access via the on board diagnostic port, OBD. within the ECU software will usually exists pin codes which are required to access particular levels of the on board diagnostics, without these pin codes you will not be allowed to complete many servicing procedures.

Mike, many thanks for your answers to my questions.

Obviously we need to avoid losing car keys to avoid a big bill but I wonder if there is any significant difference in durability between manufacturers.

I often discuss topics we discuss with others and have repeatedly been told that Renault keys are fragile, both the remote control variety and keyless entry devices.

I have been fortunate with VW keys. One of mine survived a hot machine wash. Hopefully all car keys can withstand this sort of abuse.

MIKE says:
2 December 2014

You were indeed fortunate that your key survived however that’s testament to Volkswagen build quality ( and can i say huge slice of luck ), in general the build quality of remote keys correlates directly with the build quality and reliability of the manufacturer main products, i agree the various key card’s issued by Renault and many of the Citroen and Renault remote ‘ flip keys ‘ do not stand up to scrutiny, they are very poor quality, however most vehicle keys have been designed and produced to last an expected component life of three years,
specifically designed to cover the standard warranty they issue with the vehicle thus enabling them
to charge for replacements when they fail.

I hope it’s not as bad as that, Mike, though obviously you have more experience than me. In discussing car keys with people since the start of this Conversation I have found many people who have never had any problem with their keys, apart from when they need a new battery.

I kept my last car for ten years and the key I used daily (the one I washed) was still going strong on its original battery. My current car has a key of the same design and I’m expecting it to perform as well.

I don’t know why durability of car keys fascinates me, but it seems more interesting than sport. 🙂

I recently had a conversation with a company director issued a tender from a car manufacturer supplier to provide a capacitor
for use in a dashboard, during the various meeting’s they eventually produced two capacitor’s, one was high spec with excellent temperature tolerance with an expected life use of 8 – 10 years, the other had a low temperature tolerance and expected usage of 3- 5 years,( variations in temperature have a huge effect on electronic components ) they chose the latter as it was 23% cheaper, the dashboard began to fail on some vehicle’s after two years but not on others, Therefore my earlier point about the components used by different manufacturer is confirmed by the fact that good quality products last longer than poor quality products, however of course how the product is used, where it is used, maintenance etc.. are all
contributing factors to how long any product will last.

I know about this Mike, but the considerable variation in the life of electronic components can be used to our advantage where manufacturers offer cars with a decent warranty. If a manufacturer offers a three or five year warranty they need to be sure that the failure rate of electronic components is so low that they don’t have to pay for repairs to many cars during the warranty period. This means that most owners are unlikely to have a problem in twice the period. This only works with a decent warranty period and does not work as well with non-electronic problems such as remote controls losing their buttons or plastics cracking after a few years.

I’m hoping that car manufacturers do not exclude keys from their warranties, other than for battery replacement or abuse.

We need manufacturers to include ten year warranties on kitchen appliances, boilers and other consumer durables. It’s gradually happening and might put an end to manufacturers using third rate components to save a few pennies.

MIKE says:
2 December 2014

Ten year warranty !!!! i can hear the boardrooms shrieking with laughter from here, joking aside
there are companies that have such belief in there products, Kia offer a 7 year warranty which clearly reflects the confidence in there products however i do not believe that could ever apply to vehicle remote keys in there current form as there would be to many contributing factors that would invalidate any proposed warranty, however in the not to distant future keys as we know them will no longer exist, there is a high probability your car ‘key’ will be directly linked with your mobile phone,
your retina, fingerprint etc….all those things are possible and could be produced now……..
but one way or another the manufacturers will design a system that either requires a monthly payment or something similar.

Over not too many years, we have seen a gradual increase in warranties offered by car manufacturers. Vauxhall offers a lifetime/100,000 mile warranty for the original owner. I’m sure there must be a catch but the only unexpected exclusion I could find is that it does not cover wiring harnesses. Some washing machines and other kitchen appliances are available with five or ten year warranties, either as standard or as special offers. John Lewis offers a two year warranty on all electrical goods and five years on all TVs. We are not there yet, but I’m optimistic that ten year warranties will come but we, the consumers, have to push for them.

I don’t doubt that car manufacturers will find ways of extracting money for us in the future. None of us want unexpected bills, hence the attraction of long warranties, but some drivers seem content to pay out substantial amounts to update satnavs etc.

MIKE says:

I fully support the idea but am of the opinion that any goods offered with a warranty anything above 7 years would reflect on the product being way above the budget of most consumers, yes there are products advertised with ten year warranties, i recently purchased a fridge freezer and the samsung version offered the very same ten year warranty, however on closer inspection the warranty applied to the motor and nothing else,most warrantoies contain many exclusions that many ppeople only find out when the repair is required, regarding Vauxhall’s ‘ lifetime warranty ‘ would be at best a six year warranty based on average household yearly mileage, the realistic solutions is lease for all products,
long term lease agreements for your car,. washing machine, home computer etc…..that cover repairs, replacements etc…perhaps one leasing company could provide goods for anm entire home at a reasonable cost.

Car manufacturers have introduced year/mileage warranties to protect themselves from unfair claims from heavy users. A fridge or freezer is in continuous use, so a simple warranty is appropriate, though the manufacturer would not get away with advertising a long appliance warranty and covering only the compressor. With a washing machine it would be appropriate to give a warranty for a number of years or washing cycles, whichever comes first. The Vauxhall warranty is helpful to people like my neighbours who are retired and cover about 4000 miles a year. With smartphones, tablets and laptops there’s no point in having a long warranty because the technology soon becomes outdated.

Leasing may be the way forward but it needs to be fair to light users.

Meanwhile back at car keys, you might be interested in the tale of one of our contributors who parked their Land Rover in their garage and the car battery ran down, so they could not open the door with the remote control. The only mechanical lock was on the offside, which was close to the garage wall meaning that the door could not be opened.

Mike & wavechange,
Excuse me butting in on your exchanges (very interesting).

Am I reading that a new key is needed for a battery change?

Is this due to power loss in the ECU?

Same thing for any battery disconnect?

MIKE says:
2 December 2014

No you would not need a new key, the example of the Land Rover is very unusual however there would have been options available to the car owner particularly if they were members of a motoring organisation to open the vehicle without damage, alternatively they could purchase a simple device which puts a temporary charge on the remote key, not an instant solution of course, and this would not apply to those vehicles that use a re -chargable battery.

Bib1 – Sorry if I’m confusing you. 🙁 I have changed a few batteries in car remote controls. Some are easier than others. If the operating range of the remote control is less than that of your spare key it’s probably time to change the battery.

If the vehicle battery is flat then there is no power to operate the door locks. A few days ago a friend left her lights on all day and could not get into her Toyota Yaris, which has a keyless remote control. Inspection of the remote control revealed a door key that has remained hidden for five years. After a jump-start, all was well. There should not be a problem if you can open the door with the lock. My car has only one lock, though it is hidden under a plastic cover. At least it is on the driver’s side.

MIKE says:
2 December 2014

Actually the apology should be from me, sorry for the confusion, end of a long day, yes most ‘ keyless ‘ vehicle remotes incorporate an emergency key which can operate a mechanically operated door lock, and yes in some case’s these emergency barrels are behind a cover, although if you look closely there are usually marked with an key symbol. Yes it should always be on the drivers side
but that is not always the case.

I’ll leave you to give advice Mike. You know a lot more than me. But I will be carrying on the fight for longer warranties because I’m fed-up with manufacturers selling us products containing low specification components.

I recently misplaced my car key ( put it in with my Sat Nav ) and made enquiries how to replace it . It is for a Hyundai Accent , which is 8 years old .. The amount I have been quoted by Hyundai and the AA is £350.80 . Plus I have to get the car to the Hyundai dealer to be coded , which is 11 miles away . The car is a modest car , very reliable , but only about £15000 when it was new so how do Hyundai justify the cost of this replacement key ? I have sent a message to Hyundai asking this question and I am waiting with interest for their reply . I am a Hyundai fan as this is my 7th Hyundai but I find this charge extortionate .

My last car came with two keys and an emergency key and I assumed that the new one would be the same, otherwise I would have asked for an extra one as part of the deal. I appreciate that car keys require programming these days but I suspect that there is a good profit to be made on selling replacements, as with sat nav upgrades.

I have always considered three keys necessary for a car – one to use, one to lose and one to keep for emergency. The only benefit of having only two keys is that I have stopped losing the one in daily use. It comes out of my pocket as soon as I get home.

Michael says:

main dealers do stand to make a high level of profit
When supplying replacement keys for modern vehicles, in recent years
Profits/margins on the sale of new cars can be as low as
6% or less which is substantiationally lower than in previous years,
Therefore they all have looked at after sales
Services to generate income and profit, hence the cost of replacement keys.
My suggestion is to search for a local auto-locksmith,
In most cases they can provide the same service as the main dealer
But at 60% less than main dealerships prices, they will also come to you
To supply and programme the key which is much more convenient,

Good luck

I paid Canadian $ 200/- and waited for Two hours at a Honda dealership for A Civic 2003 Duplicate Key. I felt that the key was valued on it’s weight in Gold, and was wondering whether I should have purchased a Gold Chain or ornament instead.

In this age of Ultra-surveillance and totalitarian monitoring, and community policing, enhanced security and policing,:

1. Do we really need keys at all?
2. What all the fancy keys with embedded DNA
3. What about cars with car-tracking and high-tech alarms

The keys are just an excuse to rip-off the flesh of living people, and sadly the Governments allow the Corporations to get away with these crimes which cannot be justified under any circumstances, but the Corporations are able to get away without accountability every time and cannnot be held responsible for anything should the executives lose the profit-sharing, and benefits, and allowance, and all the PERKS. What a bunch of jerks and idiots!

It would have been nice if this had been proof read. Several sentences have been cut short
“The average price of a key from Audi, Mercedes, BMW, Ford, Vauxhall and ” — yes and what??
“Ford was the cheapest at £130 (admittedly this isn’t for ”
“I rang another Ford dealer and found that a keyless fob for a new Fiesta ”
Seems to me that Which? has just
Surely it’s not unreasonable to expect that
Not long ago I was shopping at

Very disappointing

You are so right, it can really add up to get a car key replacement, but like you said if we take everything into consideration, it’s going to be worth it in the end. For me, I love keyless entry, the convenience, and they last for so long, don’t they essentially pay for themselves?

I have a renault clo the flip key fell out of my pocket and has not worked since quote from my local renault dealer £240 shocked

Google “Renault key repair” and you should get a selection of people who may be able to repair your key. I have had two Espace keys fixed this way (cracked circuit boards) for around £25.

Hyundai dealer wanted £300 for replacement central locking key for my 2009 i30. I found a local garage which replaced it for £144 incl programming.
Worth shopping around – look at the Internet too

I recently lost my key for a Hyundai i40. It is a keyless transponder so I don’t actually have to insert the fob as it detects the signal. Havinig contacted the dealer he didn’t know the actual price but suggested it could cost £300. I then contacted Hyundai directly and once again couldn’t give me an actual price but suggested it could cost £450. Her reason for the expense was that it had to be reprogrammed. For someone who has got an MSc in electronics and computing I know this is is total nonsense, the greatest cost would be in the electronic circuit board and that is totally insignificant. My question is what are the manufacturing costs and what is the profit margin. I can tell you…”Extortion”. Absolutely disgusted.

Maybe we should be bargaining for an extra key or two when we buy a new car. It seems very mean to provide only two keys for a car that costs as much as it does. As you say the circuit board should not be expensive to make.
