In extreme cases, the blade can snap off inside the lock or ignition, requiring a specialized extraction and the cutting of a brand-new blade.
4. Electronic Component Failure
Inside the fob, there is a Printed Circuit Board (PCB). Solder joints can crack due to impact, or micro-switches can become removed. In addition, water damage is a frequent perpetrator for electronic failure, resulting in brief circuits that prevent the buttons or the transponder from working.
