Anti-Theft Explorer 2002, unlocking doors
 

I have a Explorer 2002 with Automate system and have some problem with unlocking the doors after one night.

When Ilock the doors and arms the car, then I can disarm and unlockit with the remoteunder a few hours. But if I amarming and looking the doors and try to disarm it after the night, then it will not unlook the doors only disarm it. Is there anyone who knows why? Should it be that way?
