This started happening a few months ago, whenever I lock my doors, it makes this weird buzzy noise, as if it keeps locking up rapidly about 15-20 times. What could be wrong? and how can I fix this??

thanks for any help you guys can give me.

Without tearing the doors apart, I can only guess. (The crystal ball's in the shop being reconditioned)
There MAY be a lock actuator binding, and what you're seeing is it's trying to do it's job.
Look for one of the actuators needing more effort to move.

thanks you

 

Here's my guess.
Inside the door lock actuator mechanism an arm pivots/rotates and at the end of it's travel it hits a rubber bump stop. Over time the bumper wears and slips off or rotates around the post holding it. First it rotates until a thinner section of the rubber pad is all that's between the arm and the post holding the bumper, and this is why it's gotten louder (less rubber to deaden the sound). Eventually that arm will wear through the thin part of the bumper and the bumper will slip off altogether. When this happens the arm moves about 1/4 inch past where it's supposed to stop and hits the post itself. By moving past the designated stopping position the system doesn't see that the doors have locked and it repeats the locking process over and over and over, until finally you pull your hair out and tear it apart to fix it. Have fun!

Oh yeah, to fix it remove the actuator mechanism, take it apart carefully and use a zip tie to hold the rubber bumper in place (fat side of the bumper toward the 'arm', and fat end of the zip tie on the backside of the bumper out of the way. Or spend $140 on a new actuator.
