Cost of hiring a professional for car key replacement
When your car key breaks or goes missing, one of the first big decisions is whether to call your car dealer or a local auto locksmith for a replacement.
Dealers often charge more - typically £200 - £500+ for modern keys - because they use official parts and have direct access to your car's software.
Average dealer vs locksmith costs:
| Service Provider | Price Range |
|---|---|
| Dealership | £150 - £500+ |
| Locksmith | £100 - £250 |
Locksmiths, especially those specialising in automotive services, can offer a more cost-effective solution – take a look at this guide to see the hourly rates of locksmiths.
However, you need to make sure they have the necessary equipment to program modern keys if that’s what you need.
Note: Emergency call-out fees for lost keys can significantly increase the cost, especially outside normal business hours or if you're located far from the service provider.
Replacement car key types and costs
Replacement car key costs and car key replacement prices vary widely based on the key type, from basic to high-tech models. Here's a breakdown of common types and how much a new car key costs.

How your model affects the cost of a new car key
Here is a step-by-step breakdown of how your car’s make and model affects car key replacement cost:
Step 1: Check how budget-friendly your car is
Models like Ford Fiesta or Vauxhall Corsa usually cost £100 - £300 to replace. These have simpler keys with plenty of aftermarket options, so it’s easier on your wallet.
BMW or Land Rover keys often hit £400–£1,000+ (even £5,000 for fancy exotics). This is because they use special smart keys and dealer-only programming that jacks up the price.
Step 2: Look at the year:
Cars made after 2015 with keyless entry need expensive coding tools that most locksmiths don’t have, pushing how much a new car key costs even higher.
However, if you have a vintage model car, it might need a specialised service and drive up the price.
Step 3: Match your exact model and trim:
Always double-check your car’s year and version for spot-on car key replacement prices. For example a mid-range Toyota might land around £200 - £450.

FAQ: Common questions about car key replacement costs
Are there any hidden costs associated with car key replacement?
While the quotes you receive should cover the basic costs of the key and the service, be aware of potential additional expenses. These can include emergency call-out fees, extra charges for programming sophisticated keys, or even travel expenses if you're located far from the service provider. Always ask for a comprehensive quote to avoid surprises.
Can I reduce costs by providing my own keys or materials?
Purchasing your own keys and presenting them to a locksmith for programming and cutting can sometimes save money. However, it's crucial to ensure compatibility with your vehicle. Discuss this option with your service provider beforehand, as some may not work with parts they didn't provide due to warranty or reliability concerns.
How do I choose between a dealership and a locksmith for key replacement?
Your choice may depend on several factors, including cost, convenience, and the type of key you need. Dealerships are typically more expensive but can be a safer option for keys with complex programming. Locksmiths offer more competitive pricing and can provide quicker, more convenient service, especially in emergency situations. Check reviews and confirm that the locksmith has experience with your car model and key type.
How can I prevent losing my car keys in the future?
Consider using a Bluetooth key finder, which can help you locate misplaced keys using your smartphone. Additionally, keeping a spare key in a safe, accessible place can save you from a lot of trouble and expense should you lose your primary key.

UPVC Gearbox / Lock mech stuck in the door. Trying to replace.
Anonymous user 05/10/2026 - 8.04 AM
Hi, any advice would be much appreciated. I've removed all the screws along the metal strip on the door (leaving the x3 torque screws) but the actual lock element won't come out. Any videos you watch on this it seems to come free very easily. I've read that some are secured with rivets but I can't tell if this is the case with mine (T&T branded if helps). I wonder if anyone had any good tips for wiggling it free? I'm conscience of using excessive force and have tried inserting the spindle and pulling towards me from both sides with the door open but with no joy. Thanks in advance UPDATE: Thanks to those who have replied, appreciate you taking the time to do so. Having read the responses I'm just updating the question as looking at my original post it wasn't particularly clear. So I've completely removed both the euro cylinder lock and handle plates on both sides (including spindle) and taken out all the screws (bar the torque screws) along the multipoint mechanism strip where the mushroom cams etc are. The problem is that when I gently pull the strip away the lock centre case gearbox doesn't budge and come away with it as it should. Not sure if it is riveted or just very tight so reluctant to force it. Again, thanks in advance.
