- Smart Key (Proximity Fob): These never ever need to leave a pocket or bag. They permit push-button start and touch-inductive door locking.
Typical Reasons for Replacement
While loss is the most regular reason for seeking a replacement, it is not the only one. Key fobs are electronic devices susceptible to several failure points:
- Physical Damage: Cracked housings or broken internal circuitry from being dropped.
- Water Damage: Submersion in water often shorts out the fragile circuit board.
- Worn Buttons: Over time, the rubber or plastic contacts inside the fob can wear down, making the buttons unresponsive.
