I have a 91 accord and every time i get in the car to drive somewhere it starts beeping, its a constant beep beep beep.. it doesn't stop for a while and start again its continuous from when i turn on the car untill i park and turn the car off. I've tried buckling both seat belts (maybe a bad weight sensor), I've tried resetting the computer, resetting the door locks.. still nothing. every now and again it won't happen for like a day, but the next day the beeping starts again and its driving me nuts! any suggestions of what it may be or how to fix it would be much appreciated.

 

Try spraying a little WD-40 in the driver's seat belt buckle. The seat belt switch contacts may be sticking.
