Key fob replacement and programming in Bellevue

A key fob that stopped working, a smart key that went through the wash, or a push-to-start car that says “key not detected”. Fobs fail in a few predictable ways, and most of them can be fixed at your car.

We replace and program remote-head keys, separate remotes and proximity smart keys for many domestic, Asian and European vehicles.

Replace, reprogram or just a battery?

Sometimes the fix is small: a battery, or a fob that lost its pairing. Sometimes the fob is damaged and needs replacing. We start by checking which one it is, so you do not pay for a new fob you do not need.

Key fob not working after a battery change?

Check that the battery is the right type and sits the right way up, that the contacts are clean, and that the case is fully closed. Some vehicles need the remote to be resynchronized after a battery change. If it still does not work, the fob or its programming may be the issue, and we can test both.

Push-to-start smart keys

Proximity keys let you unlock and start the car without taking the key out of your pocket. They need to be programmed to the car’s security system, and most include an emergency blade that we cut to your locks.

Fobs bought online or at a parts store

A fob you buy still has to be programmed to your car, and aftermarket fobs vary in quality and compatibility. Some program fine, some never will. Send us the part number or a photo before you book, and we will tell you whether it can work with your car.

What affects the job

A new battery or a re-pairing is a small job. A new smart key that has to be cut and programmed to the car is a bigger one. The model year and the type of fob decide which one you need. See what affects the cost, and check the neighborhoods we cover across Bellevue.

Questions about key fobs and smart keys

Can you program a key fob I already bought?

Sometimes. It depends on the fob and the vehicle. Send us the part number or a photo and we will check before you book a visit.

Can AutoZone program a key fob?

Some parts stores can program certain remotes for some vehicles. Smart keys, fobs with an immobilizer chip and many newer cars usually need a locksmith or the dealer.

My smart key works but the car says key not detected. What is wrong?

Often the fob battery is low. If a new battery does not fix it, the fob or its pairing may be the problem, and we can test both on site.

Do you work on European smart keys?

We program many European models. Systems vary by model year, so give us the exact year and model and we will confirm first.
