This comprehensive guide aims to provide you with all the information you need about the cheapest ways to replace your car keys in the UK, helping you make an informed decision without breaking the bank.
Understanding Different Types of Car Keys and Their Replacement Costs
Traditional Metal Keys
Traditional metal keys are the simplest type of car keys and were commonly used in older vehicles. These are basic mechanical keys without any electronic components.
Average replacement cost: £10-£50
The cheapest option for replacing traditional metal keys is typically through a local locksmith. They can cut a new key from your existing spare or by using your vehicle’s key code. This process is relatively quick and inexpensive compared to other key types.
Remote Fobs and Key Cards
Remote fobs and key cards are more advanced than traditional keys and include buttons for locking/unlocking doors remotely. While they contain electronic components, they don’t have transponder chips.
Average replacement cost: £50-£150
The cost variation depends on the complexity of the remote system and your vehicle’s make and model. Generic aftermarket remote fobs can sometimes offer the cheapest solution, though they may not always include all the functionality of an original manufacturer remote.
Transponder Keys
Introduced in the 1990s, transponder keys contain a small chip that communicates with your vehicle’s immobilizer system. The car will only start if it recognizes the correct transponder signal.
Average replacement cost: £75-£200
Transponder keys require specialized equipment for programming, which contributes to their higher replacement cost. The cheapest options are typically through independent auto locksmiths who specialize in key programming but charge less than dealerships.
Key Fobs with Integrated Transponders
These combine remote capabilities with transponder technology in a single unit.
Average replacement cost: £100-£250
These types of keys are more complex to replace due to their dual functionality. The cheapest replacement options can usually be found through specialist auto locksmiths who have invested in the necessary programming equipment.
Proximity (Keyless Entry) Keys
Modern keyless entry systems allow you to unlock and start your vehicle without removing the key from your pocket or bag.
Average replacement cost: £150-£400
These are among the most expensive keys to replace due to their advanced technology. Main dealers often charge the highest prices, while independent specialists might offer more competitive rates.

Can I get a replacement car key without the original?
Yes, you can get a replacement car key even if you’ve lost all your original keys. However, this typically costs more as additional security procedures are required. You’ll need to provide proof of ownership (V5C logbook, ID, and proof of address) and the vehicle’s VIN number. For modern vehicles, this may involve replacing or reprogramming the vehicle’s immobilizer system.
Will my insurance cover lost or stolen car keys?
Many comprehensive car insurance policies include key cover as standard or as an optional extra. Coverage typically ranges from £500-£1,500 and may cover replacement keys, reprogramming costs, and even car hire while waiting for replacement. Check your policy documents or contact your insurer to confirm your coverage.
How much is a replacement car key UK cheapest option for a basic metal key?
For traditional metal keys without electronic components, high street key cutters offer the cheapest option at approximately £10-30. Local locksmiths may charge £20-50 depending on your location and vehicle model.
What’s the cheapest way to replace a transponder key?
Independent auto locksmiths typically offer the cheapest transponder key replacements, ranging from £75-150 depending on your vehicle make and model. This is significantly less than main dealer prices, which can range from £120-250 for the same service.
How much does it cost to replace a keyless entry/proximity key?
Proximity keys are the most expensive to replace. Main dealers charge approximately £200-400 depending on the vehicle brand. Independent specialists may offer replacements from £150-300. Luxury vehicle brands like BMW, Mercedes, and Land Rover are typically at the higher end of this range.
Can I replace just the key fob shell if the electronic components still work?
Yes, if only the physical casing is damaged but the electronic components still function, you can replace just the key shell. This is the cheapest option, costing approximately £5-20 for the shell. Many online retailers sell replacement shells, or you can purchase them from auto parts stores.
Are main dealer replacement keys better quality than those from locksmiths?
Main dealer keys use original manufacturer parts, which some vehicle owners prefer. However, quality independent locksmiths use components that meet or exceed OEM specifications. The functional difference is minimal in most cases, despite the significant price difference.
Can I get a car key cut at Timpsons or similar high street shops?
Yes, Timpsons and similar high street key cutters can cut basic metal keys and some transponder keys. Prices typically range from £10-80 depending on key complexity. However, they may not be able to program advanced electronic keys for newer vehicles, which would require additional services from an auto locksmith or dealer.
Do online replacement services work as well as in-person services?
Online replacement services can work well and often offer competitive prices. However, the process typically involves multiple steps: ordering the key, having it cut locally, and then getting it programmed. For electronic keys, you’ll still need a local specialist to program the key to your vehicle, which adds to the total cost.
Can mobile locksmiths replace any type of car key?
Most professional mobile locksmiths can replace nearly all types of car keys on-site, including complex proximity keys. They carry specialized equipment in their vans for cutting and programming. However, some very rare or exotic vehicles might require dealer-specific equipment.
Will a replacement key work with my car’s immobilizer?
Yes, properly programmed replacement keys will work with your vehicle’s immobilizer system. The programming process synchronizes the new key’s transponder chip with your car’s immobilizer. This is why simple key cutting isn’t sufficient for modern vehicles – the electronic components must be correctly programmed.
Can I program a new key myself to save money?
Self-programming is possible for some vehicle models, particularly older ones (pre-2010). Online guides and videos exist for DIY programming, and some aftermarket keys come with instructions. However, most modern vehicles require specialized equipment for programming, making DIY approaches impractical or impossible.
If I replace my key, will my old key still work?
This depends on how the replacement is done. If you’re simply adding a new key, your old keys will continue to work. However, if you’ve lost all keys and are concerned about security, locksmiths can reprogram the immobilizer to reject any previously programmed keys, ensuring lost or stolen keys can’t be used.
Do I need to replace all my keys if one is lost?
No, you don’t necessarily need to replace all keys if one is lost. However, for security reasons, some owners choose to have their immobilizer system reprogrammed to reject the lost key, especially if they suspect it was stolen rather than simply misplaced.
What should I do if I lock my keys in the car?
If you’ve locked your keys in your car, contact a mobile locksmith who specializes in vehicle lockouts. Costs typically range from £60-120 depending on your location, time of day, and vehicle complexity. Avoid attempting to break into your own vehicle as this may cause expensive damage.
How quickly can I get an emergency replacement key?
Many independent locksmiths offer emergency services with response times of 30 minutes to 2 hours. Emergency services typically incur additional callout fees of £50-100 on top of standard replacement costs. For common vehicle models, same-day key replacement is usually possible.
What if I need a replacement key on a weekend or holiday?
Emergency locksmiths operate 24/7, including weekends and holidays, though you can expect to pay premium rates (typically 20-50% higher than standard weekday rates). Main dealers are generally closed at these times, making independent locksmiths the only option for urgent replacements.
Can I drive my car to the locksmith if I have a damaged key?
If your key is partially functional and still starts the car, you can drive to a locksmith to save on callout fees. However, if the key is severely damaged, attempting to use it might cause further problems with the ignition or immobilizer system. In these cases, it’s safer to have a mobile locksmith come to your vehicle.
How much is a replacement car key UK cheapest if I still have one working key?
Having a spare key made while you still have at least one working key is the cheapest scenario. Independent locksmiths typically charge £60-150 for programming additional keys, which is significantly less than emergency replacement when all keys are lost (£150-400+).
Are aftermarket keys reliable?
Quality aftermarket keys from reputable suppliers are generally reliable for most everyday vehicles. They may lack some aesthetic features of original keys but function similarly. For high-end luxury vehicles, manufacturer original keys are sometimes preferable due to their specialized technology and integration with vehicle systems.
Can I claim a VAT refund on key replacement?
No, replacement car keys for personal vehicles are subject to standard VAT rates with no refund available. However, if you’re replacing keys for a business vehicle, you may be able to reclaim the VAT as a business expense. Consult with your accountant for specific advice regarding your situation.
Is it worth paying more for a main dealer replacement?
For most drivers, the premium paid for main dealer key replacement (often 40-100% more expensive) doesn’t offer proportional benefits over independent specialist options. However, for very new, rare, or high-end luxury vehicles, dealer replacements may offer advantages in terms of warranty coverage and system integration.
