Common Reasons for Keyless Entry Failure
Here are some of the most common reasons why your keyless entry system may not be working:

- Faulty Key Fob: If the key fob has been damaged or is malfunctioning, it may need to be repaired or replaced.
- Issues with the Vehicle's Receiver: The receiver in your vehicle that communicates with the key fob may be malfunctioning. This could be due to wiring issues or a blown fuse.
- Software Glitches: Modern vehicles often rely on software to manage keyless entry systems. A software glitch can sometimes cause the system to fail.
