Mine wouldn't allow the car to unlock the doors on the key button but would disarm the alarm!! The unlock function on the center console was also failing to work, but all locking functions worked correctly and this was the sign that the GM5 module was on the way out. Don't know if the coupe or the CSL uses the same module.
