A fob that stops working is not always a big repair. Run through these checks first. Half the time it is a battery you can change in two minutes.
Check the battery first
Most fobs use a flat coin battery, often a CR2032 or CR2025. The number is printed on the old battery. If the range has been getting shorter for weeks, the battery is the likely cause. Replace it and test again.
Start a push-button car with a dead fob
Many push-to-start cars let you start the car with a dead fob. Hold the fob right against the start button, or place it in the backup slot some cars have, then press the brake and the start button. Your owner's manual shows the exact spot for your car.
Try the spare
If the spare works and the main fob does not, the problem is that fob, not the car. If neither works, the problem may be in the car's receiver or immobilizer, which a locksmith or dealer needs to check.
Signs it needs programming
Buttons do nothing even with a new battery, the car says key not detected, or the fob was replaced or repaired. A fob can lose its pairing after a battery change on some cars, or after work on the car's electronics. Reprogramming is done at the car.
When to replace it
A fob that got wet, was run through the wash or has a cracked board usually needs to be replaced. We make and program a new one at your car.
