If the car fails to begin and displays a "Key Not Recognized" message, try holding the fob versus the designated "key symbol" on the guiding column or center console. This permits the car to read the transponder chip by means of induction, even if the fob battery is dead.

2. Physical Button Failure

Gradually, the rubber membranes inside the fob can wear down. If a specific button (like the trunk release) stops working while others operate, the internal micro-switch might be damaged. In this case, the shell can sometimes be changed, but often a brand-new fob is needed.

3. Disturbance

High-power radio towers, cell phone battery chargers, or even being in close distance to a smart device in a pocket can sometimes disrupt the fob's signal. If the fob isn't working, try moving it far from other electronic devices.

The Future: Smartphone Integration
