i fcuked up big time.. broke my lock on my integra 1990
 

i was removing the little piece that fits between the door handle and the lock and i tried removing it cuuz it was cracked. Well i couldn't remove it and suddenly i broke or jammed the lock in the lockin position. I cant open the driver side door at all how can i fix this problem!!!

maybe replacing the lock ?......
the whole lock assebly but might require new keys i think....but yeah..

you might have to try taking the handel off from the inside and try to get at the lock mechanism that way? dont know how bad it is man

posting some pictures might help

If you have to replace the lock cylinder a honda or acura dealership should be able to code the new cylinder to the old one. Did it all the time when I worked parts at a chevy dealer.

^^^^ this random dude is right!

take the door panel off then look at the lock lines and try to un-lock and see what's jamming it.
