Trunk (boot) Locked

Help! Closed trunk (boot) lid yesterday and now won’t open, key turns but nothing, on 66 mk10.
Anybody have info on how to open or who to contact. By the way, drivers door does same thing.
Thank you

Sounds like the catch is sticking , try pressing down on it and a few sharp blows with your fist at the same time !

Thanks for reply, as new owner, I had no idea about lever beneath lock. Problem solved.
