Warning Signs the Keyless Entry Transmitter is Failing
- Reduced range: You have to be closer to your car for the remote to work.
- Intermittent operation: Sometimes the remote works, sometimes it doesn't.
- Buttons not working: Specific buttons on the remote stop responding.
- Car alarm issues: The alarm goes off randomly or won't disarm with the remote.
- Keyless entry completely dead: The remote stops working entirely.
How to Test if This Part is the Problem
- Check the battery: Replace the battery in the key fob with a new one. This is the easiest and cheapest first step.
- Try a spare key: If you have a second key fob, see if it works. If the spare works, the original fob is likely the problem.
- Check the car battery: A weak car battery can sometimes cause issues with the keyless entry system.
- Inspect the receiver: The receiver in the car could be faulty, but this is less common. A mechanic can test this.
Common Failure Causes for This Part
- Battery corrosion: Old batteries can leak and damage the remote's internal components.
- Physical damage: Dropping the remote or getting it wet can cause it to fail.
- Button wear: Over time, the buttons can wear out and stop making contact.
- Electronic component failure: Internal circuits can fail due to age or environmental factors.
