I drive a 2004 CLK320. Recently my car makes a mono tone beeping noise when I lock the door using a keyfob. In order to stop the beeping, I have to hit the panic button then unlock the door. Also, hitting the panic button triggers another off beeping sound but unlocking it make it all stop. Hence, I can't seem to lock my door. Any advice would be greatly appreciated. Thanks in advance for any input.
