Hi guys, I got a 2004 Honda Civic thats driver door lock won't turn with the key. When you put the key in the door to lock it, it will not turn. It will not lock or unlock at all. Does anyone know how I can fix this issue?

Currently I have to go to the passenger side and unlock the car like that to get in. Any help would be appreciated, thank you!

 

there's most likely a bunch of gunk in the door latch linkage. if you take the door off, clean as needed and use shin etsu grease on the components, you should be fine.

 

I sprayed graphite spray and WD-40 in the lock, but still nothing. Wouldn't that have helped it out if it was gunked up?

 

The linkage is the rod and levers that go to the inside lock. Slim jiming is a usual cause of bent linkage. Next is a tumbler mismatch with the key.

 

Guys, is there anyway I can use the passenger side lock on the driver side?
