The key itself may be damaged
You need to replace your keys at the same time as replacing your car locks
You need an extra copy of your car keys because your car has multiple drivers

Replacement costs by key type
Gone are the days when a car key was simply a piece of metal shaped to fit your car's lock. Nowadays, car key technology is becoming increasingly sophisticated, with remote and transponder chip models.
This is great in terms of convenience and security. That said, with the addition of this technology, new car key replacement costs are rising rapidly.
Let's look at the four most common car key types and the costs to replace them:
1. Manual car key replacement
A flip key is perhaps the most commonly used manual key used to start a car's ignition. This type of key consists of a plastic shell that houses the key, which flips out at the touch of a button
It's also one of the cheapest vehicle key replacements, costing around £160.
2. Transponder car key replacement
Transponder car keys are more secure than remote keys. They use specialist chips to recognise the key through a unique code. The car then authenticates the code before allowing entry.
The cost to replace a transponder car key jumps up to £240.
3. Keyless entry replacement
High-tech and convenient, keyless entry car keys work by sending a radio wave to connect the car and the key fob, so you can unlock your car with the push of a button. This is often paired with a push-button start, so you don’t need to insert a key.
But all this technology comes at a price, and a bit of a faff. If you misplace your key fob, you'll need to reprogramme your car, which will cost approximately £280.
4. Remote keys
Though designed to allow you to unlock your car from a distance with a click of a button, you still need to insert the key into the ignition to start the vehicle. The buttons can break, and these keys are more expensive to replace.
Prepare to spend approximately £320 for a remote key replacement.
Key replacement costs for popular vehicles
Replacing a car key in the UK can vary significantly in cost, depending on the vehicle's make, model, and the type of key required.

What affects the cost of car key replacement
There are a huge variety of factors that dictate the cost of replacement car keys, including:
1. Key type:
As explored earlier, various types of car keys, including manual, remote, and transponder keys, are now available.
Generally speaking, the higher the specification of the key is, the higher the cost to replace it.
2. Vehicle make and model:
Each car manufacturer uses different types of car keys and security measures, which (you guessed it), affect the cost of replacements.
Take a Bentley Diamond Key. This premium car could set you back a whopping £8,000. This is in contrast to an entry-level Ford, which is much more affordable £275.
You might be surprised to hear that not only does the make of a car influence the car key replacement cost, but even different models in the same range will impact the price. So it's always best to contact a dealership, garage or locksmith in your local area to get an exact quote.
3. Programming
There are three main types of keys requiring reprogramming. These are:
Keys for remote or keyless entry
Keys with an integrated transponder chip
Flip keys and key cards
Some locksmiths can reprogram a cloned key for you in a few minutes. The time it takes can depend on whether your vehicle needs to be present to allow information from your vehicle to be read while the new key is programmed.
Reprogramming your key fob may take longer if specialist diagnostic technology is required, and some vehicles require a login or security code or PIN to be entered before or during this process.
How much does a locksmith charge to program a car key?
The price ultimately depends on the make, model, and year of your vehicle, and the process that is required to program the fob you need. Typically, you can expect to pay between £50 to £200.
If your vehicle was manufactured pre-1995, then you won't need to worry about reprogramming. Only cars produced after 1995 are required to have immobiliser systems that work by having an electronic chip with a transponder in the key fob.
4. Urgency and location
The price will also vary depending on your location. For example, London companies will charge more than others due to high demand.
The time of day will also impact the cost. For example, emergency out-of-hours car key replacements will likely cost more than if you can wait until the next day. You might need this service if your car keys are stolen.

Where can I get my car key replaced?
If you've been fortunate enough to have never misplaced a car key until now, even knowing where to go to get a car key replacement can be confusing.
The following list covers the most common options for replacement car key services:
Auto locksmiths: Quick and affordable, auto locksmiths will likely have the correct equipment to replace and program most types of car keys. Some even offer a call-out service, where they will come to wherever you are located
Brand dealership: Your local dealership may be able to replace your car keys. However, they will only hold blank keys for certain car models and may not have the right equipment to programme car keys. This method of replacing car keys can be more expensive
Your local garage: If you're lucky, your local garage may have the equipment and blank keys for your make and model of car
Don't forget to check if your insurance covers lost car keys. If so, you can claim the cost of a replacement through this. However, this may affect your no-claims bonus.

Hidden costs of car key replacement to watch out
Car towing and call-out fees
Lost your key while out and about? Then you'll need roadside assistance if you've misplaced your car keys away from home.
If you're lucky to have breakdown cover, they can come to you and may be able to replace it there and then. However, this depends on the type and brand of car key you use and your policy. If not, they'll tow you to a garage or dealership to get things fixed.
However, if you don't have breakdown cover, you can still access vehicle recovery services through a breakdown provider, an emergency recovery service, or a local garage. But it will cost you.
Hiring a recovery vehicle can cost around £75 on average. Expect to pay more (typically £85 after 6 pm and on weekends) and up to £90 - £110 on bank holidays.
In addition, you will pay a mileage to be towed, often around £1.50 per mile.
Replacing or reprogramming the immobiliser
Discovered it's the immobiliser that's the culprit? Unfortunately, this is where things get more pricey.
To reprogramme the immobiliser, you'll pay roughly £300 and an eye-watering £750 to replace the immobiliser.
Battery replacement for the key fob
Realised it's just the battery that needs replacing? Happy days. This is a cheap and easy fix costing just £15. However, if the reprogramming procedure needs to be completed by a dealer, this may cost slightly more.
Key insurance or warranty costs
Some car insurance providers may include key coverage as standard with their comprehensive car insurance, but not all do.
You can usually get car key cover added to your policy as an optional extra for around £36 a year. Just be aware that you might need to pay an agreed excess.
When buying car insurance, some policies include keycare. This useful service involves putting a fob on your key ring with a number to call if anyone finds your keys.
