How to Get a Replacement Car Key in Hertfordshire

Few things are more frustrating than losing your car key or discovering it no longer works. Modern keys are more than just bits of metal – they’re packed with electronics, transponders, and sometimes remote-control features. That means replacing them isn’t as simple as cutting a new one at the local hardware shop.

So, if you find yourself without a working key, what’s the best way to get a replacement?

Step 1: Check if you have a spare

It sounds obvious, but the first thing to do is double-check whether you’ve got a spare key. Many cars are supplied with two keys when new. If you’ve misplaced the main one, having a spare will save you time and stress and you can use it to get a copy made.

If you don’t have a spare, don’t worry, there are reliable ways to sort it.

Step 2: Identify your key type

Not all keys are created equal. Before ordering a replacement, it helps to know what you’re dealing with:

Traditional keys – Basic metal blades, usually found on older cars.
Transponder keys – Contain a chip that communicates with your car’s immobiliser. Very common on vehicles built after the late 1990s.
Remote keys – Include buttons to lock/unlock the car remotely.
Smart keys / keyless fobs – Allow push-button start and proximity unlocking.

The more advanced the key, the more technical the replacement process.

Step 3: Choose where to get a replacement

You typically have three main options:

Main dealer
- Can supply and program a new key.
- Usually the most expensive and time-consuming option.
Automotive locksmith
- Often quicker and cheaper than dealers.
- Can cut and program keys on-site.
- Ideal if you’re stuck without any working key.
Specialist workshops (like Technical Vehicle Solutions)
- Offer key cutting, programming, and coding.
- Can handle modern transponders and remote keys.
- Provide a balance of cost efficiency and professional service.

Step 4: Provide the right details

To order a replacement car key, you’ll usually need to provide:

Proof of ownership (logbook or V5C).
Vehicle Identification Number (VIN).
The make, model, and year of your car.

This ensures the new key matches your car exactly and can be coded correctly.

Step 5: Key cutting and programming

Once your replacement key is ready, the next step is programming it to your vehicle. This involves:

Cutting the blade to match your locks (if applicable).
Coding the transponder or smart key to communicate with your immobiliser.
Testing functions like remote locking, unlocking, and push-to-start (if fitted).

A professional workshop ensures the process is smooth and secure.

How long does it take to get a replacement key?

Basic keys – Sometimes available the same day.
Transponder or remote keys – A few hours to source, cut, and program.
Smart keys – Can take longer if parts need to be ordered.
