Why choose a replacement key service?

Car keys, fobs and remotes can be quite complicated. AA Key Assist takes the hassle out of getting spare car keys.

  • All our technicians are fully trained and DBS background-checked, so you’re in safe hands.
  • We work with vehicle manufacturers, including big names like Ford, BMW and Vauxhall.
  • We follow manufacturer security processes and use dealer equipment wherever possible.
  • Our mobile car locksmiths can be more convenient and cost-effective than a dealership.

  • The different types of car keys range from transponder keys to lock transmitters. They all need to be programmed and some need special software and diagnostics. For broken, stolen or lost car keys, it's best to get a specialist auto-locksmith to help.

Can I get a car key made without the original?

Yes. Our equipment reads the key's design directly from the car's lock. So if your car key's lost or stolen, we'll cut and program a new one without needing the original. We’ll also disable any old keys as part of our service, to give you peace of mind that no-one can use the missing keys.
