My daughter lost a bag with keys and address information, so the
question is basically what should we do with the locks (Yale cylinders)?
Changing the cylinders is dead easy but could a locksmith modify the
existing cylinder and make new keys for it, or should I not bother and
just get new cylinders out of B&Q?

Change the cylinders and while you're at it fit proper mortice locks as
well, because a Yale won't stop anyone.
