Difficulty Rekeying Locks

[Pickmequick]

My question to the OP is: Why do you want all of these locks to operate with the same key combination? Or even have the same keyway?

Probably as already said.

I have all Euro profile cylinders in my house and we only have 1 key for 5 locks and my Moms house is on different keys but mine is a master key to them.

Nothing worse than having a massive bunch of keys to cart around wrecking your mobile phone.

I think the usual way to rekey Euro cylinders is to pick the lock and then use a special follower tool. Can be a bit tricky at first though.
