You say that you get "a false alarm", but you are not clear at all as to what you mean by that. Our "alarm" system is the siren AND the lights. If you get sound but no lights, you are not "getting a false alarm".

To fully evaluate what is going on, these questions must be answered:

1) When locking the car with the FOB, what sounds do you hear and where do such sounds appear to come from?
1A) When locking the car with the FOB, what lights flash and how many times do they flash?
2) When unlocking the car with the FOB, what sounds do you year and where do such sounds appear to come from?
2A) When unlocking the car with the FOB, what lights flash and how many times do they flash?

These tests tell us what the CLP/SSM, the BCM and the SKREEM are doing.

Another test you should do is to lock and unlock the car by inserting the key in the driv'ers door lock and turning it to lock or unlock the car. What do you get then?
