My door looks won't open when I use the key pad. I can only open the door with the key. But ever once in a while they work fine. what could this be? Please help

 

Mine did the same thing. I took off the dash cover under the steering wheel. There you will find a gray box on the right side that is the door lock timer. On mine, I took it out and apart expecting to work on it, but on a whim just plugged it back in there and the keyless entry and power locks have worked fine since. Must have been a loose connection or something that will probably show up again someday, but for now it works.

 

Hmm my doors don't always lock with the pad. Seem to get stuck half way down sometimes unlock when left alone once unlocked while I was driving . Alarm ignition lock works but sometimes find the lock buttons up when coming back to the car. Have been thinking this was either mechanical or electrical and not wanting to take off the door panel to check. Will try the magic grey box reinstall and hope it works. Perhaps search function will come back on the forum with some other fixes for now I am looking for a faith healer or the grey box. Thanks!

 

You guys are right about the door lock timer, EXCEPT, when you pull it out, slide out the circut board located inside the grey box, and resolder all of the old solders. Look specficaly for ones that are cracked or discolored. They get old a crack, losing connection. Do it, It works!
