Dead Key Fob Battery: The Usual Suspect
The most common reason for keyless entry failure is a dead key fob battery. This is an easy fix. Simply replace the battery with a new one, ensuring it’s the correct type for your specific car model.
Faulty Key Fob: Beyond the Battery
Sometimes, the problem lies within the key fob itself, even with a new battery. Internal components might have malfunctioned or become damaged. In such cases, reprogramming or replacing the key fob might be necessary.
Receiver Issues: The Car’s Perspective
Another potential issue could be with the car’s receiver module. This component receives signals from the key fob. If the receiver is faulty, it won’t be able to interpret the signals, preventing the car from unlocking.
