my car alarm only seems to work on occasions like on a nice sunny day and i have to be really close to the door in order for the censor to work and the car to lock, but then the sensor won't work and i have to put the key in the door to open it which is embarrassing as the alarm would go off and i have to put the key in the ignition to turn off the alarm. i also had to unplug the siren because it sounded really awful like it was struggling to make a sound. I no that the siren is one part of the problem but my main problem is with the sensors they aren't working and i have manually lock and unlock the car. i not sure if its alarms Anti tow system module or the car sensors?
