2. Physical Wear and Damage
Modern "flip keys" have a pivot mechanism that can deteriorate with time. If the blade feels loose or does not lock into place, it signifies structural tiredness. Similarly, worn-down "teeth" on a standard blade can make it difficult to turn the cylinder.
3. Damaged Button Pads
The rubber or plastic buttons on a key fob are subject to consistent friction. With time, they can crack or collapse, exposing the delicate printed circuit board (PCB) underneath to dirt and oil.

If the control panel shows a "Key Not Recognised" mistake or a pad-lock sign, the transponder chip inside the key might have become desynchronised or physically harmed due to being dropped.

Can a car key be repaired if it has been through the washing device?
In lots of cases, yes. The key needs to be disassembled, cleaned up with isopropyl alcohol to eliminate cleaning agent residue, and the battery replaced. If the circuit board hasn't shorted out, it might still function.
