Hi, I just replaced a remote starter/alarm in a 2003 Malibu. One problem I am having with both units(old and new) that were installed is that if the vehicle sits for about 20 mins or longer, when I go to unlock the doors with the remote, the alarm will disarm but the doors will not unlock. I have to either lock/arm the car first or start the car with the remote as if to wake it up before I can hit the unlock button to actually unlock the doors. Also I am using the dome light as the door trigger and I usually have to wait 10+ seconds till the dome light turns off until I can arm the car properly, is there a better trigger to be using? Does anyone have any suggestions to fix the problems/annoyances?? Thanks

It is a 2003 CLASSIC. The epsilon came out in 2004, so that model year you had both options available. Thanks

I just tried the double pulse to unlock, let the car sit over 20 minutes and nothing. I have to hit the lock button, re-lock the doors, then I can use the unlock and it will unlock the doors but now with a double pulse. Any other thoughts??

well, never seen a mali. fall asleep.maybe try this, get rid of the dome light as you're trigger and try these. Door 1 | 18ga. GREEN/ Black (-) (driver door only) at driver’s kick panel in Black connector | Door 2 | 18ga. Lt. Blue (-) (passenger doors) at driver’s running board where harness “tees” and goes under seat (for coupes go to passenger’s kick panel) |
the alarm will have a wire that will turn on domelight upon unlock(dome light supervision)use this to send a neg to the white domelight wire. i assume whoever did the original install put a resistor on the unlock? generally on cars that go to sleep, pulsing a door trigg or domelight will wake them up.

o, thats just great, ill type it all again, so u dont have to decypher that.lol.......grab the normal door triggers.........GREEN/ black at drivers kick.......and light blue where harness tees under drivers seat both (-)......then use the wire on the alarm that is used to kick on the domelight(domelight supervision) this wire needs to go to the white domelight wire(in drivers kick). ive never seen a mali fall asleep, so this all i can think of doing.is there a resistor on the unlock wire?

Yes I have a resistor on the unlock wire it reads 1500 ohms as it should be, I also added diodes to reduce the risk of power going where it shouldn't.
