Hi,
No, not yet as i haven't taken the time to dig into the door.
The doors are always unlocked when in my garage so its a low priority for now.

 

same here, if you ever do i'll probably copy you lol. im on the look out for clear tails and wheels now .

 

I have a bit of an update.
I bought this door lock assembly to help understand how this all works.
The exterior metal key door lock is just a lock cylinder and a cable, pretty basic.
Here is a breakdown of the latch assembly. The lock cylinder cable makes a 180 degree bend when its mounted.
I'm thinking if i can loosen the 3 Latch screws enough that i can slide my endoscope in-between the latch assembly and the door frame,
then hopefully i can get a view of the end of the push-pull cable for the metal key to see how it looks.
