2002 cavalier, remote start

I installed a remote start with keyless entry on my car.  I had everything working fine and now the drivers door won't lock.  All other doors lock fine.  It doesn't even work with the button on the door.  You have to manually lock it.  It was working when I first hooked it up.  I looked for a fuse for just that door but can't find any.  Any ideas?

Another question.  Right now I have the unlock only triggering the drivers door.  I found the wire for the rest of the doors, but if I connect to both do I need to diode isolate them?  Reading some posts it seems like I should but the sticky post about it seems to only apply to triggers, do I need to do it for just unlocking?

Thanks

did the car have a factory keyless entry? it sounds like you have tied into the lock motor wires and not the lock/unlock trigger wires. one wire should unlock ALL the doors, not just the driver side.

It does have a factory alarm.  I tied into the unlock wire from the bcm.  I had it hooked to both but I was worried about the diode.  I think I will hook it back up.

What really bothers me is that the drivers door won't lock.  There is a relay in the fuse box that is labled drl.  could that be drivers door lock?

DRL is Daytime Running Lamps, so it wont be that. so that door unlocks but wont lock? and the rest of the doors do nothing, correct? what wires did you tie into, and what setup did you use? positive trigger? 5 wire?

I tied into the lt blue to lock and the white to unlock.  Everything unlocks now.  All doors except the drivers door lock.  But the door lock button on the door won't even lock the drivers door now.  It was working before.  I'm thinking I shorted something out but not sure where to look.  Could the lock actuator have gone partly bad and only work in one direction?
