Warning Signs Your Keyless Entry Transmitter is Failing

How to Test if This Part is the Problem
- Replace the battery: This is the easiest first step. A weak battery is a common cause of key fob issues.
- Try a spare key fob: If you have a second key fob, see if it works properly. If it does, the problem is likely with the original fob.
- Check the car's receiver: This is more difficult to do yourself. A mechanic can test the receiver in your car to make sure it's working correctly.
- Inspect the key fob: Look for any physical damage to the key fob, such as cracks or broken buttons.
Common Failure Causes for This Part
