What we do with fobs

A fob does two jobs. The buttons lock and unlock the car, and on most cars the same fob is what lets the engine start. Both have to work before we leave.

Before you call

Have the year, the make and the model ready. That tells us on the phone whether your car can be done at the curb.

✓
Sometimes it is only the battery. If that is all it is, we tell you.
✓
Push to start and smart keys are part of the job. Most makes and models.
✓
We do not work on Tesla.
✓
Everything is tested before we leave. Buttons, doors, trunk and the engine start.

A lost fob can be taken off the car

When we program a new fob, on many cars we can also remove the lost one, so it no longer opens the doors or starts the engine. If the fob was stolen rather than lost, tell us, and where the car allows it we make sure it stops working.

Questions people ask

Do I have to go to the dealer?

Usually not. We program most fobs at the car. If yours is one of the few only a dealer can do, we tell you on the phone.

Can you replace only the case?

Often, yes, if the electronics inside still work.

Do you need proof that the car is mine?

Yes. Identification and the registration, or another document that ties you to the car. We check every time.
