Warning Signs of a Failing Keyless Entry Transmitter
- The buttons on your remote don't work.
- You have to press the buttons multiple times to get a response.
- The range of your remote is getting shorter.
- The remote works sometimes, but not others.
- Your car alarm goes off for no reason.
Testing the Keyless Entry Transmitter
- Check the battery: A weak battery is the most common cause of remote failure. Replace the battery with a new one and try again.
- Test the remote's signal: Some auto parts stores have testers that can check if your remote is sending a signal.
- Try a spare remote: If you have a spare remote, see if it works. If the spare works, then your original remote is likely the problem.
- Check the receiver: The receiver is in your car. It gets the signal from the remote. If the receiver is bad, no remote will work. This requires a mechanic to diagnose.
Common Failure Causes
- Dead battery: The most common cause.
- Water damage: Getting the remote wet can damage the electronics.
- Physical damage: Dropping the remote can break internal components.
- Worn buttons: Over time, the buttons can wear out and stop working.
- Receiver issues: Problems with the car's receiver can prevent it from recognizing the remote's signal.
