Sliding door won't open

The main thing with stuck locks is to try and limit damage.  It may not be possible.  If your door is double locked then you may not be able to simply move rods inside to unlock even after wrecking the trim to get at the lock.  I would definitely spend time using any tips you can find here and elsewhere about opening a locked door.  Diagnostics might help and it's worth a try but if the problem within the lock itself you might end up getting brutal anyway.  You can buy many used trim parts fairly cheaply online if it comes to it.  Good luck and keep us updated. :-)    

Hi All

Progress of sorts!

This was the first piece off, the plunger top snapped from the rod like it was designed that way, will fix that later

I was then able to detach the leading edge of the window blinds

And gradually wrangle the trim away so I could get my hand inside to where the catch was, and activate the lever using a sacrificial finger

The door opened, and the rest of the trim came off without losing too many retaining clips.

Seems the end of the release cable has frayed and come adrift from the catch, so all (!) I need to do is extend/replace the cable.

To do that I need to remove the catch from the door by unbolting it.

Would someone point me in the right direction as to what head and size these are, and possibly where I might get a driver for them?

I'm hoping I won't need a robot arm or air hammer to get them out...

Cheers

Steve
