2001 hyundai elantra's driver side lock will not lock the other three doors in the car. What is the name of the part needed to fix?

There should be a fuse that runs the power locks. Check and make sure it didn't blow.

check your battery in key

door lock actuator might be faulty or bad electrical contact
take off the door panel and diconnect and reconnect the wiring, you might need to change door lock actuator

I have just purchased a 2001 hyundia elantra, the other day i was filling up with petrol. the doors automatic lock the doors with my keys still inside the car, the doors make a clicking noice all the time

yes

The door LOCK/UNLOCK actuator is siezed. You'll need to replace it.

take an old auto antenna or, a very stiff metal rod and, using a plastic blade (like a plaster knife) bend the glass on the driver's side door; at the top of the door; gently outward; place a rubber or, wood spacer (eraser, wedge etc) between the door frame and, the glass: you only need one inch space; use the rod to press /pull the button / lever on the passenger side

wellits a smilple thing they have this round wire with a handel and they will yake the strip of ur driver side window don't worry it can be put back no need to buy a new one . and he will push the wire that is connecting both the handels and then open ur door.

there is a short or a signal from the un-locking switch that is triggering your locks.

you have a switch manually to lock and un-lock your doors, the unlocking circuit is making contact.

you can try playing with your switch to un-short the switch or open it up ang check it.


tnx 4 using fixya,

There is a "bar" that attaches to the lock like a lever pulling and pushing the door. Over many years and hundreds of unlockings it breaks from the plastic...I am in the same boat. It won't cost that much....take it to the dealer..the part is around $13.00 to replace
