you should be able to turn off alarm via key in drivers door if not test all doors to make sure they unlock. if any door will not lock that door latch will need replaced if work ok then try disarming alarm from trunk key or from the passanger door. if that works,you may need to have the key recoded to the car.

I have a similiar problem occasionally. In my 97 vw, it usually happens when the battery terminals are loose. I just take them off, clean them and reconnect and the problem goes away for several months.

Try disconnecting the negative battery cable for 20 minutes and accessing the door.

First, try to disable the alarm using the key in the truck lock. If that doesn't work....
You should be able to pull the lock cylinder out of the handle using the key. Insert the key, then gently twist and pull. Once the lock cyl is out, be careful when you remove the key in order to keep the keying blades in the right order. Once out, do whatever you can to knock the remainder of the lock cylinder mechanism loose, use a very narrow screwdriver or the like, and keep going until you can look through the hole with a flashlight and see a slot in a white plastic circular piece. Then use a flat head screwdriver to unlock the door, after the battery has been reconnected.
The parts to fix the lock cylinder are cheap, and well worth replacing. The door handle is held in place by a single bolt, should be a t30 torx. Remove the bolt then work the handle loose.
It will be difficult to reassemble corrrectly without having done it previously but you may be able to find images on the internet to help you.

If you don't have the remote then its pretty much useless. I have seen at Pep Boys where they sell replacements for the factory/dealer installed alarms. Or just remove the alarm completely and reconnect everything the way it was.
Without knowing what brand alarm it is a person cannot honestly answer how to disarm it as they all work differently.
If you know a brand and model you may be able to find downloadable instruction on the manufactures web site.
