I have a remote starter that went bad (module) Anytime I would use the key fob or the power locks to lock/alarm doors, the car would try to start up and I would disengage by pressing the brake pedal. Dealer disconnected the remote starter from the starter but then when I would lock the car at night, in the a.m. the battery would be dead. Topk the car to get a new remote starter installed but still having the same issue. When I lock the car at night, in the a.m. the battery is dead. Have no clue how to resolve this problem but need to asap.

Hi Mark,

There is battery drain somewhere and it should be quite bad unless the battery is faulty.

You need to isolate the problem through the main fuses under hood. Remove the battery negative terminal and attach a test lamp between it and the battery.

If it lights up ( do not use high wattage, light not work) there is a voltage drain.

Start pulling out the fuses and the one that stops the lamp from lighting is the circuit that you should go for. Check all its related components.
