i have an 89 supra turbo. the car alarm goes off alot when i unlock my door. it wont do it all the time but like 10 % of the time it will. its the stock one. is there a fuse or anything i can do to fix it easy or disable it? its loud and annoying everyone looks at me in the parking lot when it goes off. it sucks.

it sounds like the key alarm switch isn't making proper contact. you might want to make sure that its secured properly or is funtioning.
