A fob that stops working may need a new battery, reprogramming or replacement. Try the battery first, then ask a shop whether your fob can be reprogrammed.
Key takeaways
- Try the battery.
- Programming varies by vehicle.
- Call first.
Battery first
Most fobs use coin batteries.
Reprogramming
Some fobs can be reprogrammed.
Replacement
Broken or water-damaged fobs.
Smart keys
Push-start systems vary.
What to bring
All existing keys.
When a fob needs replacing
Cracked cases, worn buttons and water damage are signs a fob is near the end of its life. A fob that works intermittently may have a failing circuit board. Replacing the fob and programming a new one costs more than a battery but less than failing completely. Keeping a second fob programmed is the best backup.
What programming involves
Programming links the fob's code to the car's receiver. Some vehicles allow owners to program a fob using a sequence of key turns and button presses. Others require a scan tool to write the code. Because procedures vary by manufacturer, ask first. Never buy a used fob without confirming that it can be reprogrammed, because some are locked to the original car.
Cost and time expectations
A battery swap for a fob takes minutes and costs little. Reprogramming a fob you already own is usually cheaper than a new one. A replacement fob plus programming costs more and depends on the vehicle. Ask for the total before you agree, and ask whether the shop can program the fob while you wait. Bringing all existing keys makes programming easier and sometimes cheaper.
