Why do the car locks keep locking and unlocking on my Chevrolet lumina it's a 1992 year

SOURCE: how to change the serpentine belt on a lumina euro 3.1??

I found on my 92 lumina 3.1 the easiest way to change the belt is to have two people handy (you and a helper) push the belt tensioner (which is more in the middle of the belt system, its the only thing that has give when pressure is applied) down (which will loosen the belt) have your partner slip the belt off the altenator (which should be on the very top of the belt system on the passenger side) and just pay attention to the way the belt is routed as you remove it, put the new one on (routed correctly) push the tensioner again have your partner slip it back over the altenator....and you have a new belt on with no tools :)

just pay good attention to the routing of the belt, and i also think there is a black cover over the belt which needs to be removed before the old belt can be taken off (if you dont see it at first you will find it) it has 3 bolts i think and also a diagram of the routing....

TIP: the tensioner will take some muscle to move down, and yes the belt is running over it....

Dude, the same thing happened with my EL falcon. It turned out to be the key fob! The buttons were sometimes sticking and all of a sudden it would re-lock. Ususally it would unlock then immediately relock. Leaving no time to get into the the car. Sometimes we would be driving and the Alarm would go off without touching a thing. I ditched the Key Fob and all was well again.
I hope this helps

Passenger side of the fender under the hood - check the fuse relay box - about $12.00 a piece - they do go bad from time to time.
exchange the power lock relay with another one and test the locks.
then put the relay back and go to the autostore.

I recently repaired a similar problem for a friend of mine. I posted the procedure on our website. Here's the link:

SOURCE: changing battery 2001 Lumina and radio lock up.

someone (hopefully you) set the 3 or 4 digit security code on the radio. when power is disconnected, like if someone steals your radio, the radio locks and cannot be used. the code can be from 000 to 1999. the hour and minute buttons are used to enter the numbers. 2000 choices - good luck
to unlock the system:
1 turn on ignition - LOC will appear
2 press MN and '000' will appear
3 press MN again until you see the last 2 digits of the code you want to try
4 press HR until you see the first 1 or 2 digit of the code you want to try
5 press AM FM
6 SEC will appear if you got it right - LOC will show if you got it wrong
good luck
