aburas Posted January 9, 2007 Share Posted January 9, 2007 I have a 91 LS400 and my passenger door lock will not open with the key. It operates just fine using the door lock switch inside the car and the remote...but not with any of my keys. The other doors work fine with the key. Any ideas?

larryp Posted January 9, 2007 Share Posted January 9, 2007 Have had same problem with both driver door lock and ignition switch. Took lock cylinders apart and removed a couple of the pins that were sticking. Not the greatest remedy in terms of security, but it solved the problem. Not difficult to do, just have to be real careful not to lose pins or springs when you take it apart. Quote Link to comment Share on other sites More sharing options...
RFeldes Posted January 9, 2007 Share Posted January 9, 2007 You could also try spraying wd 40 and let it sit for an hour or so and then spraying some teflon in there. Quote Link to comment Share on other sites More sharing options...
