Typical Signs That a Car Key Needs Repair

3. Harmed Button Pads
The rubber or plastic buttons on a key fob go through constant friction. Over time, they can crack or collapse, exposing the fragile printed circuit board (PCB) underneath to dirt and oil.
4. Transponder Issues
If the control panel shows a “Key Not Recognised” mistake or a pad-lock symbol, the transponder chip inside the key might have become desynchronised or physically damaged due to being dropped.
