We can get you back on the road in no time at all and it won’t cost you an arm and a leg! It doesn’t even have to be an emergency!

Exactly what is a transponder key?


In layman’s terms, a transponder key is a manufactured accessory that comes with a car and provides the radio transmission link between the car and the key. It means that a key can be programmed to start one specific, individual car thereby reducing opportunities for theft. Without its transponder key, a car can’t be driven. 

Does every car have an immobiliser?

In most modern cars the transponder chip is incorporated into the top of the car key. Since 1995 it has been a legal requirement for vehicles to be fitted with an immobiliser system for which a transponder key is required. It is in the form of a microchip that contains a serial number that the car manufacturer’s key programmer has made unique to that key.


When inserted into the ignition, the key transmits an electronic request to the engine control units (ECU) and the immobiliser box, which then allow the car to start. If the car doesn’t recognize the serial number as the one it was programmed with, it won’t respond to the message and the car won’t start.


The transponder key science bit sounds complicated but at least you know that this wireless, electronic communication between car and key only takes milliseconds yet its failure to operate can cause one expensive headache UNLESS… know how to contact The Auto Locksmith.

You don’t need to go back to the dealer, have the car towed anywhere – in fact, you don’t have to worry. One phone call and you can put your mind at rest as The Auto Locksmith will come to you and take care of the rest. We offer car key programming for the majority of vehicles on the road and are often called upon by organisations like The AA, RAC and Green Flag to assist.

If you are buying a car it will include a transponder key so you should ensure that you get at least two keys. Sometimes keys are lost, so having a second validly, programmed transponder key is important. If you buy a car second hand and it only comes with one key, it is recommended that you get a duplicate car key cut. All you have to do is call The Auto Locksmith and we will create a replacement key incorporating a transponder chip that is correctly coded to your car. No time required in having to find a garage– our vehicle locksmith expert comes to you.

Be car security aware

The technology involved in programming keys to specific cars has led many vehicle manufacturers and insurance companies to consider cars with transponder keys to be virtually theft-proof, but they’re not. If you know that your car keys have been stolen, make Newell Glass & Locks your second call after the police. Even without having the actual key, The Auto Locksmith can erase the transponder serial numbers logged in your car, ensuring that the thief with your keys won’t be able to steal your car! We can then cut you a replacement car key and program them to your car to ensure a perfect communication between car and key.

How Much Do Replacement Car Keys Cost?

The average price of a new car key supplied from a main dealer in the UK is £252. The table below shows the main dealers price of a new car key for the top ten best selling cars in the UK. The cheapest car key is £216 for a Volkswagen Polo, whilst the most expensive is over £330 for a Mercedes A-Class key.

Volkswagen Polo£216

Factors that affect the price of replacement car keys

We have identified four common factors that are likely to have an impact on how much replacement car keys cost:

The cost of replacement car keys varies from model to model

When looking at how much replacement car keys cost it’s important to be aware that there is no set price for a particular vehicle manufacturer’s key. Different models will utilise different keys, all at different prices. For example a Ford Fiesta key could be as low as £230 whilst a Ford Mondeo key could cost £280.

A car key replacement price will also fluctuate depending on the year of registration

Similarly to the model variations, prices can also fluctuate depending on the year of first registration. For example a 2010 Vauxhall Corsa key currently costs £217, whilst a 2017 Vauxhall Corsa key costs £230.


The spec of the model may also impact the cost of a car key  

It’s not a given that all models of a certain year or mark will have the same associated cost for a new car key. Certain editions and spec upgrades could mean an upgrade to the car key. For example a Ford Fiesta 2014 could use a flip style remote key that is turned in the ignition, or it could also use a proximity style key fob, meaning the car is started by the push of a button.


Other factors that could impact car key cutting prices

It is important to remember that most main dealers are franchises and the price of a replacement car key may vary from franchise to franchise. The geographic location of the dealer could also influence the price, with dealers in the South of England likely to be the most expensive.

Main dealers in the UK do not provide a mobile service for key programming, so should you lose your only car key you will need to budget for the cost of recovering your vehicle into their workshop.

If you do not have a record of your vehicles key number and immobiliser code the dealer could possibly charge an extra fee for supplying this.

How is the price of a replacement car key from a main dealer broken down?


Whilst it may seem like some main dealers have literally plucked a price from out of the air, there is often a reason a replacement key for your car may be priced higher than expected.  When you purchase a replacement car key from a main dealer there are essentially three elements that you are paying for.

Replacement car keys cost UK motorists millions


Losing your car keys is extremely irritating and always seems to happen at the worst possible time. According to an RAC report collated in May 2018 43% of UK drivers frequently misplace their car keys. This amounts to over 16 million drivers.  Fortunately for the majority of these drivers it is normally a temporary loss and they eventually find their keys. The report also revealed that just over 2 million UK motorists admitted to losing their keys for good. This means supplying new car keys is big business for main dealers and auto locksmith replacement car keys specialists.

The report, which surveyed 2000 UK motorists uncovered the following “key facts”:

Why are car keys so expensive?


The majority of people that have never had the misfortune of losing a car key are shocked when they discover how much replacement car keys cost. Unlike domestic house keys, car keys are highly sophisticated electronic devices that contain a PCB, transponder chip and battery.

As already explained the blank key can be expensive to purchase for the dealer or locksmith, meaning the end price to the consumer is already more than expected. A blank car key is cut using state of the art automated key cutting machines, which cost thousands of pounds to purchase and maintain. In order to make a profit the dealer or auto locksmith will factor in the cost of cutting the key.

Programming tools for coding a new key can cost tens of thousands to initially purchase, with extra ongoing costs associated for licensing and installing new software.  A cost will also be added to cover the time taken for cutting and programming the key. Anything up to one hour can be expected for such a labour fee.  

When you take all the factors into consideration and remember whoever is supplying the key will need to make a profit, the price of a replacement car key is often justified. So how much do replacement car keys cost? Probably more than most motorists would expect, but not so much when you fully understand how sophisticated a car key actually is and what’s involved in supplying one.

Five of the most expensive car keys

If you own one of these cars you DO NOT want to lose your key:

Data suggests that the cost of replacing car keys is on the rise. A ford Fiesta key cost just £162 back in 2013, but five years on the price has risen by over 41% to £230.  Also in 2013 a replacement key for a Nissan Qashqai would have cost £180, but you can expect to pay as much as £300 if you walked into a Nissan main dealer today. That’s more than a 66% increase!

The price increase could be due to the improvements in car key technology and the introduction of proximity keyless start keys, which are able to start the car without the user having to insert the key into the ignition.

Top tip from the car key geek


“The cheapest option is not always the best option! You can buy a new TV for £70 but it won’t have the same picture quality as a slightly more expensive trusted brand option.  The same is true with auto locksmiths – If you spend long enough calling around you can probably find a lower price, but trying to save £10 on a new key could end up costing you up to £1000. It’s very easy for an inexperienced locksmith to corrupt a body control module using cheap non genuine tools”.
