might be partially true..you have a problem with (most likely) the drivers actuator,and or microswitch.The GM(general module) doesnt get a clean signal from your drivers door that it has locked,so it disregards the previous lock signal....the later GMs dont do this.My car does the opposite,but only form the deadlocked position.If i unlock,the car immediately locks again.Most times the second attempt works.On very rare occasions the drivers door stays locked and the rest of the car is unlocked.I dont have a remote so this behaviour is from the key in drivers door.
