This was a ball-ache but got it sorted now.
I pulled the cover away from the brick exposing a small gap and got my young daughter to reach her skinny arms through the gap and release the locking mechanism at the sides. Surprised myself that it actually worked
Hi I don't know if this has been posted before.
Just moving in to a new property and the garage door had no key.
I opened it up and removed the barrel to get a replacement and then disaster the garage door was closed and is now locked shut.
How do I get in to fix ?
