Common Issues Requiring Car Key Repair
Car keys are subjected to day-to-day wear and tear. From being dropped on pavement to being squashed in pockets, the physical and electronic integrity of the key is constantly at threat. There are a number of primary reasons a key might need expert attention.
1. Physical Damage to the Blade or Shell
The most apparent kind of damage is a snapped or bent key blade. This typically happens when a lock is stiff or when the key is used to pry something open. In addition, the plastic "shell" or casing can crack, triggering the internal buttons to fall out or the key blade to end up being loose in the flip-mechanism.

In time, the little tactile switches on the internal circuit board can break off or end up being unresponsive. This results in a key that can start the car by hand but can not lock or unlock the doors from another location. Oftentimes, the rubber pad on the exterior of the key deteriorates, exposing the fragile electronic devices to wetness and dirt.
