When inserting the key into the ignition or door locks, if you notice a delay in response or find yourself having to jiggle the key excessively, it’s a sign of a worn-out or damaged key. This inconsistency can lead to ignition problems or difficulties in locking and unlocking your car.

2.5. Ignition Cylinder Issues

If you experience difficulty turning your car key in the ignition cylinder, it could indicate a problem with the cylinder itself. Over time, the ignition cylinder can become worn or damaged, making it challenging to start your vehicle. In such cases, it’s advisable to replace the car key and have the ignition cylinder inspected by a professional.
