Not all car keys are created equal and neither are their replacement costs. The type of key your vehicle uses is one of the biggest factors in determining how much you’ll pay. Here’s a breakdown of typical replacement costs in the UK for 2025:
Standard Manual Keys – These traditional metal keys are the cheapest to replace. They don’t include chips or remotes and are usually cut within minutes.
- Cost: £20 – £50
Transponder Keys – Used in most cars built after 1995, transponder keys have a chip that communicates with your vehicle’s immobiliser. Replacing them requires both cutting and programming.
- Cost: £120 -£200
Remote Fob Keys – These keys combine remote control buttons with a standard key blade. They unlock doors remotely and often include a chip.

Emergency Call-Outs – If you need a replacement key urgently say, you’re locked out late at night-expect to pay a premium for emergency services.
- Additional Cost: £50 -£150 depending on the time and location
Factors That Affect The Cost of Car Key Replacement
Type of Car
The type of car you drive will play a major role in the cost of car key replacement. Luxury cars and vehicles with advanced security systems will likely be more expensive than the average car.
Number of Keys
Getting a second spare key cut at the same time is usually cheaper. At UK Auto Locksmith, for example, you can get your second key at up to 50% off.
Where You’re Getting the Key Replaced
Different locksmiths and auto dealerships may charge different prices for key replacement, so it’s important to shop around and compare prices before deciding where to get your new key made.
Your Location
Urban areas like London tend to have higher average labour and callout fees. However, UK Auto Locksmith operates without a call-out charge, even in central London.
What about smart car key replacement costs?
Generally, most smart car keys require special key programming, which can add to the cost. Replacing a smart car key can range from £100 to £250.
Additionally, some models may require specialised parts unavailable to the general public, increasing the replacement cost.
Programming Fees for Smart Keys
Many modern smart car keys, especially transponder keys and smart keys, require programming to work with your vehicle’s security system. This programming adds to the overall cost of the replacement. While some locksmiths can perform this service, others may require you to go to a dealership, which can increase the cost further.
To get the best value for your money, consider contacting a professional locksmith like UK Auto Locksmith. We offer competitive prices and expert services for key replacements, ensuring you get a high-quality new car key without the excessive dealership fees.
It is important to keep in mind that replacement costs for a smart car key can be expensive. It is always best to check with your local dealer before attempting any repairs or replacements. Additionally, some insurance companies may offer coverage for lost or stolen keys, so checking with them before deciding to replace your key is worth checking.
Where is it Cheaper to Get the Key Replaced?
Dealerships: Often more expensive, with prices ranging from £250 to £600+ and wait times of several days to weeks.
Independent Locksmiths: Typically faster and cheaper – £100 to £250 with same-day service.
Never compromise on the quality of work!
Prioritising Safety & Quality Over Price when Replacing Your Car Keys
Safety and quality should always be a priority when replacing car keys. The cost of a replacement key varies depending on the make and model of your vehicle and the type of key you need. It is important to know that the cost of replacing your car keys should never be prioritised over safety and quality.
