How can I open my coldseal door ?

Had the same problem yesterday, luckily my son in law is a double glazing fitter.
He came round and looked at the problem, we eventually opened the door by removing the hinges. This meant the door would move enough to get a screwdriver in to push the hooks out of engagement.
refitted the hinges, fitted a pair of " sash jammers " to enable the door to be secured short term.

Now ordered a replacement lock.

One tip I overheard was remove the glazing/panel but that's all.
I imaging you can either access the bar that carries the locking parts and prise it up or drill holes into the plastic glazing channel to access the bar, I couldn't try it on my daughters door as I live in sussex she lives in Devon and my arms are too short. Another point is to price up a locksmith against having a new door fitted as by the sound of it the mechanism has broken anyway.
