- Faulty battery: Even though you replaced the battery, it's possible that the new battery is defective or not properly installed. Try replacing the battery again and ensure it's inserted correctly.
- Damaged remote: The remote itself could be damaged, either from physical wear and tear or water damage. Check for any visible signs of damage, such as cracks or corrosion.
- Receiver issue: The receiver in your vehicle that receives the signal from the remote may be faulty. This is less likely, as the receiver usually doesn't fail unless the vehicle has been in an accident or has experienced some other type of major damage.
- Reprogramming issue: If the remote was not programmed correctly, it will not work. Follow the reprogramming instructions carefully and ensure that you are entering the correct codes.
- Interference: There may be interference from other electronic devices in the area, such as other keyless entry remotes or garage door openers. Try moving away from any potential sources of interference and see if the remote works.
