Looks pretty standard this should fit it, use the old screws.

I have the same t bar handle lock . I don't have the keys the piece of metal with the wire attached is covering the 2 screws and the T bar handle is locked. Which is the best way to remove the lock so I can see the spigot length and replace the garage door lock.

Just turn the inside piece of metal, or take off the chains

Measure the thickness of the door, add on any extra that sticks out, or buy one with a long spindle and cut it to size

The rear of door has one pice of flat bar that the wire cable attaches to. I can pull on this to release the door but because the handle is in the lock position the bar won't turn to show the screws heads so I can dismantle the lock. Will I have to cut the bar into pieces or is there an easier way.

the rectangular plate is retained by a circlip, which prevents it falling off the spindle. You can pry the circlip off. Try not to lose it.

Here's a couple of pictures of the inside of the door

the inside of your spindle is drilled and tapped for a screw. This is so you can fix a T-handle on the inside, to open and shut the door. If you pull on the inner handle, it is released from the external lock. The screw tends to fall out and get lost. I couldn't find one to fit.

The latches that are operated by tension of the cable are easily burgled, you drill a hole through the door and push or pull on the cable.
