One of the internal doors in my daughter's flat is shut and will not open. It's a bog standard tubular latch. The door handle turns, but nothing happens. The door opens inwards, so I can't get access to the hinges. I've tried to use a credit card to slip the latch, butcan't.
Daughter returns from holiday late on Tuesday. Any suggestions, please, or do I need to get a locksmith? I thought of an angle grinder, but it might cause too much mess.
Thanks for your help.
John
