Weak Signals
If your key fob doesn't respond to the buttons of the remote it could be a sign that the signaling system is not working properly. Your car and key fob are dependent on radio signals to communicate, and weak or inconsistent signals could result in poor performance and range.

Resetting the settings on the fob can also help restore a more regular response. The procedure may differ from vehicle to vehicle.
