Car Alarms: how do you unlock, nissan maxima, nissan service

Question
i have a 91 nissan maxima and my key wont unlock the door and my codes wont work and i cant unlock it from the indside without setting off the alarm what do i do?

Answer
Short of calling a locksmith, I don't know
what I can adise you on here. I can't help
on the physical reason why the key won't
unlock the door. That's not related to
the alarm My guess is you need a Nissan service
department to help you out on this one.

If it's an aftermarket system, read some of the past
posting to read up on valet overide.
This might apply to your issues. Might not.
But like I said, nothing to do with the mechanics
of the door locks.

Let me know what they tell you.
