Tips for troubleshooting a car alarm include ensuring a secure battery connection and proper connection of all wiring. Another tip is to avoid intermittent alarms by temporarily deactivating the system until a professional performs repairs.
Faulty or malfunctioning car alarms may activate randomly or fail to go off at all. Troubleshooting such problems can involve changing the batteries in a remote-access device, inspecting the fuse box and reading the manual to ensure correct system operation. Reprogramming the system and reducing sensor sensitivity can eliminate false alarms. Disconnecting on-board electronics may also be helpful, as GPS systems and cellphone accessories may interfere with the system.
