Drivers door unlocks by pulling on OUTSIDE handle twice
Hi,
My drivers door unlocks twice when pullng on the handle from the outside. From what I'm aware, this is only supposed to happen when you use the key and turn to the left. In my case, it happens despite the key not even being in the cylinder. My guess is it is stuck in the open position. I tried putting the key in and turning it in both directions to 'lock' it but it doesn't do anything.
Does anyone know what the issue could be? Is it the cylinder that is broken? Spindle (saw this was the case on much older cars)? Actuator (door unlocks and locks fine with the remote/inside buttons though)?
Thanks!

I had this problem with my car door lock. It would not get switched back to manual locked position using the key, was getting open eveeytime if pulled twice. So i stripped the door, took lock out. There was some small shaft worn out which was retaining some lever on the lock barrel, i dont exactly remember details, but it was not engaging right. I was able to fix it by using a small size setscrew and manual file. I've made a replacement for that tiny shaft from this screw, fitted it and it worked.
Hopefully you can do same and make it work.

no worries. That pin was attached to lock barrel itself to what i can recall. I might be wrong. Was repairing it a few years back. There were tricky bits when taking it apart, took me probably 3 hours.

ok understood. I think you can remove the lock cylinder barrel without taking the door apart. Will give it a shot this weekend. Thanks again man.
