ok this is my first post, i just bought an 03 civic lx coupe and there is a problem with the driver's side door lock. i have seen a few posts about people having trouble with the power locks and having to lock their car from the outside with the key, but i am having the opposite problem. the power locks work just fine but the key lock on the outside wont turn. i am probably going to have keyless entry installed anyway but does anybody know how to fix this? thanks.

Take the door panel apart and see if something's amiss.

try some pentrating oil first, then go from there, and i mean inside the door lock assembly

bump for an answer. i have the same problem key wont turn from outside but power lock works fine. i tried taking the whole panel off and cant see any problem in the mechanism. its really hard to push down the lock manually too from inside...

i had the same problem with both doors on my ep. if i wanted to lock the doors i would have to go thru the hatch and reach a cross to unlock them. so i just went to honda and spent $75 on a keyless entry remote. Problem solved!

the lock cylinder is probally worn down to the point it doesnt recognize the key...

pull the lock cylinder out and rekey it... if you know how to do that... OR get keyless entry, and put rear door handles from a sedan on the front and remove the rods.. LOL

Just plain s#itty locks. Go to Honda and get a new one, that did it for me.

Wifey got an old Saab that had power locks. Only the drivers door would work with a key.Lack of use is equal to misuse.

well spray your key with wd40 or blaster.. and spray it into the lock cylinder.. work the key in and out.. probablly isnt going in all the way

key goes in fine, it just is really hard to turn in the lock like somethings stuck inside. i tried lube sprays, it didnt do anything. also my "safety" no lock feature doesnt work either, the thing thats supposed to not auto lock the door when its open. it locked me out once so i cut off the power cable to the auto lock lol.

well you do have to work the key in and out like 50 times... but im not sure about the corrosion you can get in vegas or chicago.. but it could be damaged

took the door panel off, sprayed wd40 on it, also bought some lock lube stuff and tried using that inside the lock. neither one worked. how much does honda charge for a new lock?
