Recognizing the signs of a failing card can help identify whether the problem lies with the car, the battery, or the internal circuitry of the card itself.

- Periodic Central Locking: The buttons on the card just work when pressed at a particular angle or pushed down remarkably hard.
- Total Inoperability: The car totally ignores the card-- no lights flash, doors remain locked, and the engine will not crank.
- Physical Damage: Cracks in the external plastic real estate due to sitting on the card or dropping it on tough surface areas.
Step-by-Step Troubleshooting Guide
