Not sure which one you need?
Most people arrive knowing the symptom rather than the service, which is fine - describing what is happening is more useful to us than naming the job. A few of the common ones sort themselves out quickly.
If the key turns but the engine will not start, that is the chip rather than the metal, and it is transponder key programming rather than a new key being cut. If the key will not turn at all and it has been getting stiffer for weeks, that is usually ignition repair rather than replacement. If you have just moved into a house, it is lock rekeying, not new locks - the hardware is almost always fine and the problem is who else has a key. If a door needs lifting or shouldering before it will lock, that is door lock repair and the lock itself is probably innocent.
Why we split it into four
These are genuinely different disciplines rather than four labels on the same van. Automotive work is largely electronic now - reading a vehicle, originating a key and programming an immobilizer has more in common with diagnostics than with locks. Residential work is mechanical and is mostly about doors that have moved over decades. Commercial work is about duty cycle and code compliance, where a door opens hundreds of times a day and some of them are legally required to open under a push. Emergency work is any of the three, done at the point where somebody is standing outside.
What is the same across all of them
We come to you - there is no shop to visit and nothing needs dropping off. We ask everybody to show they are entitled to be through the door before we open it. We aim to leave the lock, the door and the vehicle working exactly as they were, and where that is not going to be possible you will hear it before the work starts rather than after.
Each service below has a page of its own explaining how the job actually runs, and a version of that page written for each of the 42 towns we cover. Start from your town instead.
