My Alarm Arms But The Doors Wont Lock

What could be the sudden problem.

My alarm arms but the doors wont lock.

But each time i want to arm my car i have to push the door lock button. My alarm will not arm. When i push the alarm button to disarm it unlocks and doors and is fine. Have the vehicle turned off and the doors closed unlock the vehicle or disarm the alarm system by pressing unlock on your remote.

In any case this does not mean your alarm isn t armed when the doors don t work it just means the actuator malfunctioned and you just lock them manually. I have a 1997 nissan sentra with auto locks and an aftermarket alarm and when i press the arm button my alarm arms but doesn t lock my doors the unlock button will unarm my car and unlock the doors if i lock them manually how can i fix this myself. I have also tried locking it from the inside door itself. I get the standard two beeps when unlocking.

If it won t lock open the door. Press the unlock and the trunk buttons ii iii at the same time. Any advice would be appreciated. Shut the door and try to lock it.

I have to open the door and push the lock button. If it is loose or has slipped out of the mortise place it back in the mortise and tighten the screws with a phillips screwdriver. When i push my alarm button to lock it arms but doesnt lock the doors. This is more than likely linked to the alarm right.

The connecting tab can either be tightened or replaced as needed. The fix is easy too. Press and release do not press and hold. The alarm is the one that locks and unlocks the doors for me.

All the doors lock fine. When i press lock on the key fob i get the standard beep then another beep about a second later and the alarm will not arm. I have checked all.
