I can't open lock with the key.I can't turn the key.there is no problem to take the key out or put it in,just no chance to turn it.Should I change the lock?thanks for your help

firstly is it the right key,is it a new key thats not cut quite right,is it a worn key or lock.you could try a bit of wd40 or other light oil in key hole.remove lock clean and lube with light oil ,if no luck you will have to replace.if you get a like for like lock it should be simple to change whith very few tools.
