I have a problem with the lock on our Hartley curved top greenhouse installed in 2015. The dead bolt is stuck, locked. It isn't frozen I have removed the external bead to adjacent pane and the curved top bead but can only remove the top pane. Removing outside handle doesn't help to access the bolt. How can I open the lock please?

If the lock was last used some time ago the bolt may have become stuck due to moisture , debris, corrosion etc. We would suggest a penetrating / water dis-placing oil (WD40 or similar) applied liberally into the lock mechanism. This should release the lock.
