Three things we do, properly.
Hover (or scroll on your phone) to see where each one takes you.
ECU Repair
Faulty engine ECUs and modules diagnosed, repaired, cloned or replaced and matched to your car's immobiliser. Remaps via our partner tuners.
Coding
Programming, retrofits and feature activation and deactivation. Unlock the features your car already has hiding in its software.
Locksmith
Lost, spare and broken car keys cut and programmed on site with non-destructive entry. Transponder, remote and keyless.
Lost your keys? Breathe.
It happens! You've misplaced your keys, damaged your existing key, or locked your fob in the car. Tell us the make and model and we'll take it from there. It's usually sorted within the hour once we're with you.
Lockpicking and forced entry has always been a security risk, which is why cars need more than just a key blade to work. We cut, program and synchronise new keys with non-destructive entry: no smashed windows, no drilled locks.

What does 'no fix, no fee' mean?
If we can't make your key work, you don't pay for our time or effort. Simple as that.
Do you have a shop?
Yes, at 17 Fenlake Business Centre, Fengate, Peterborough PE1 5BQ, open 9am–9pm, 7 days. We're mostly out on mobile jobs, so please call before visiting so we can make sure someone's in.

Do you need proof of ownership?
