Sounds like your battery disconnect erased the sync between FOB and SKREEM Remote Entry function - which is very odd. I've had my battery disconnect for three weeks at a time and never once had to resync.
If you turn the key in the lock in the door, ALL locks should follow that. Also, the alarm should be disabled by that function, same as the FOB.
So if you can turn the key in the door and lock / unlock as well as activate and disarm the alarm, I'd focus on the CLP/SSM. If the system does not arm/disarm wiht the key in the door, its kinda hard to say if its SKREEM or CLP/SSM.
And yes, the BCM does play a role between the two. But I have a VERY hard time believing that a battery disconnect would cause the FOB sync to disappear.
There is something else at play here. Any chance of rodent damage SOMEWHERE to the wiring harness? How old is the battery?
I don't know how old the battery is. It came with the car. At rest after not having been driven for days, the battery reads 11.9v. With the engine running, the charging system reads 14.5v. and the battery voltage increases.
Unlocking/locking the driver door with the key, only unlocks/locks that door only. The passenger door and trunk stay in whatever state they are in with no change. The console lock/unlock button no longer works. I think that switch is connected to the BCM so the switch not working still could be either the BCM or the CLP.
I asked about the comparability of the BCM because some Xfires are convertible and some are coupes. The BCMs could be running different firmware specific to the coupe vs roadster.
I tried ohming the CAN between the BCM and the CLP, but the car is a 2006 and the 2005 Shop Manual showing which pins to measure across don't match the car.
I want to check the schematics tonight to see all the functions the BCM is involved in, then see which of those still work. I'm not sure if that info will be useful or not.
I checked for damaged harness and so far have not found any.
I may need to just bite the bullet and replace the CLP and go from there.
