My point is that the "alarm" isn't the problem. Neither is the security. The neighbor's remote would have to be triggering the "panic" function. Otherwise, just turning on the alarm (security) would not make the alarm sound unless the door were opened. Therefore, his question about bypassing the theft security would not be answered by bypassing it. He would have to disable the receiver, and therefore his remote function and tpms mode. In other words, apparently his neighbor has the frequency of the "panic" function of the fob and is using it, maybe even just to annoy him.

It also may be that the BCM may be acting on it's own. I have deal with several BCMs on C5s and C6s that "wake up" and start doing weird stuff. If it were me I would just remove the serial bus pin at the BCM and see if that stops it or not since it is easy to access. Could also just unplug the RFA to test.

If he removes the RFA from the equation and it does not happen again then it would seem that the truck (or something else) is the cause. BCMs can have a life of their own and I would like to prove what is the root cause.

It hasn't happened in a few weeks now. My remote needs to be reprogramed almost every 2-3 days. I pulled the connectors in both accordians in the doors and the pins look perfect with no signs of shorts or bare wires. So it must be an electrical gremlin as others have spoken to in other threads. Thanks for your inputs. Rod

Why not just pull the RFA fuse. With that fuse removed, the car will NOT respont to ANY frequency generated commands.
You will not have any Tire Pressure Sensor readings or FOB functions but,, you will be able to tell if the car is being told to blow the horn by internal OR external reasons.

Why not shut the power off, there are disconnects on the market meant to kill power to the whole car for storage.
Someone had on on the z06 I bought I just took it off, it's brass and well made.
I found this one on line it has a different style shut off but they all do the same thing.

Using a 9V battery plugged into the cig lighter keeps the radio codes on a c4 alive it should work on a c5.
