Thanks for looking!

I have a Viper 791xv and

1) sometimes when I unarm the alarm the doors don't ulock.(I have to unarm it, unlock it with my key then power unlock the other doors. The thing about it is that I can push power unlock on the door and the doors unlock.)

2) sometimes when I unarm the alarm and open the door, the domelight doesn't come. (When I close the door I just opened and open the other doors do see if the light goes on, it still doesn't.)

thanks for the help

The ford has a gem module for the door locks. This module "falls asleep" the factory keyless pulses the door ajar wire and "wakes up" the module. You can test for this by rolling down your window and locking the door from the inside. Wait about 30 seconds and try your aftermarket keyless. If it does not work hit the lock/unlock in the truck and then your aftermarket should work. This problem is not presant when you remote start the truck because the circuit is energized before you hit the unlock. Post a reply if you need the bypass diagram.
