Electronics Malfunction: The internal elements of the key fob might stop working, causing intermittent connectivity or total failure.
Programming Issues: After replacing the battery or if the key fob has been exposed to extreme conditions, it might need reprogramming.
Signal Interference: Sometimes, interference from other electronic devices can disrupt the key's signal, causing problems in opening or beginning the lorry.

Before proceeding with repairs, it's essential to precisely determine the problem. Here's a simple process to identify typical key problems:
Inspect the Key Fob:
