that's a good sign. The comfort access system uses both door handles as radio antennae and trunk to triangulate where the key is. If one goes bad (which they do more often than not)... it will start to drain your battery. Symptoms are... no detection at a specific door handle. Repeated attempts to lock or unlock. The car locking or unlocking on it's own as you walk near a side of the car. The gas filler locking over and over.
