📮 Post It — from anywhere in the UK

Order online. Choose the prepaid Royal Mail label option and we email you a postage label — print it, stick it on, drop it in any postbox.

We email you when it arrives, repair and test it, and return it by tracked post.

Good to know: your fob keeps its programming through a battery change — at most, some cars want a quick lock/unlock press near the car to resync.

Questions we're often asked

Why not just do it myself?
Plenty of people do — but many fobs are easy to crack open, and some lose buttons or seals. If yours is glued, sealed, or has been apart before, letting us do it properly is cheap insurance.

What if a new battery doesn't fix it?
Then it's usually a worn micro switch — see our car key fob micro switch repair. If we find that when your fob is with us, we'll contact you with the price before doing any extra work.

How long does it take by post?
We repair and dispatch quickly once it arrives — you'll get an email at every step.
