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.
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.

Whether your insurance covers lost or stolen car keys depends on the type of insurance you have.
With AA car insurance, you’ll be covered for damaged, stolen and lost car keys if you have comprehensive insurance with us. That’s as long as you don’t leave them in the car unattended.
If the keys, transmitter or keyless fob are lost or stolen, we’ll pay up to £1,000 towards the cost of replacing them. We’ll also pay the cost of protecting your, taking it to the nearest repairers if necessary and delivering it back to you after it’s been fixed.
If you have third party fire and theft insurance, you’ll only be covered for replacement car keys if they’re lost because of fire or theft. If you have third party only insurance with us, it won’t cover you for replacement car keys.
If you’re a Gold member, you’ll get free key insurance worth £1,500 with your membership.
That means you’ll be covered if your keys are lost or stolen. We’ll help with locksmith charges and a temporary replacement vehicle.
