Synced To Your Vehicle

Getting your key talking to your car, on-site

Most modern car keys need to be programmed to your vehicle's immobiliser before the engine will start, even if the key turns the physical lock. Our locksmith uses professional diagnostic and programming equipment to sync new or existing keys with your car, carried out at your location anywhere in Cambridge.

Whether you've had a new key cut elsewhere that won't start the car, lost a fob's connection to your vehicle, or need an extra key added for another driver, we can diagnose the issue and programme your key correctly — with a free quote before we start.

When You Might Need Us

Common car key programming issues we resolve

New Key Won't Start The Car

A freshly cut key that turns the lock but won't start the engine usually needs programming to the vehicle's immobiliser.

Key Fob Lost Connection

If your remote has stopped locking or unlocking the car, reprogramming can often restore it without a full replacement.

Adding an extra working key to your vehicle's system so multiple drivers each have their own.

FAQs

Frequently asked questions

What is car key programming?

Car key programming syncs a key's electronic chip with your vehicle's immobiliser and onboard systems, so the car recognises the key and allows the engine to start.

Why won't my new key start the car even though it turns in the lock?

This is a common sign that the key has been cut correctly but not yet programmed to your vehicle's immobiliser — our locksmith can resolve this on-site in Cambridge.

Can you programme a key if I only have one working key left?

In many cases yes, though it depends on the vehicle's make and security system. Let us know your vehicle details and how many keys you currently have, and we'll advise on the best approach.

Do you also cut the key, or just programme keys I already have?

We offer both — we can cut a new key and programme it in the same visit, or programme a key you already have, whichever you need.

Key not working with your car?
