Another issue might be a malfunctioning button. Repeated use can wear down the internal contacts, making the button unresponsive. In this case, you may need to replace the entire key fob shell or have it repaired. Sometimes, the problem isn’t with the key fob itself but with the car’s receiver. If you’ve changed the battery and the buttons seem to be working, but the car still doesn’t respond, the receiver might be faulty and require professional attention.
