I can't figure out to lock my car doors--BESIDES being inside the car.
When I open driverside door and push down on the door lock button--it doesn't want to go down and lock, unless I shut the door and then it will go down and I can hear the locks actuate. The passenger side seems to work fine, the doors will lock of course if I manually lock it outside. I wish I had that infrared gadgets, the scanners are on the doors...I'm not sure if I need to replace a part in the door or just have a keyless entry installed....this is a 91 sl 500
