Help Required! 929 Alarm goes off upon opening the door

[nikamma]

I recently bought this 929 94 couple of days ago, and i am having this problem now that when i try to open the door with my key (car doesnt have key less entry) the car alarm goes off.
i have tried opening the door with a duplicate key hoping that the new duplicate key might help as the original one is little bent. but that didnt work.

what can i do to have it fixed, can i fix it my self? if not then where do i need to take it?

ii'll appreciate if anybody can call with solution at 507-382-0723
