Just moved into my new flat.

It has DPS "High Security" locks which are (presumably) un-pickable.




they are not usually unpickable,they often have a registered slot
pattern which most locksmiths will not copy without authorisation.

In fact often mastered systems are easier to pick because they have
multiple pins per slot which allow differing keys to line them up, which
allows the picker more choices.

However, I have one key which own both the communal front door and my
own flat's door.

I guessing that means that I can't change the cylinder and get a batch
of new keys as they then wont be able to open the front door (unless
that is, there's only one common door keying).

So I'm stuck with having to hope that previous tenants haven't kept a
key (Or worse, given one to their friends).

How is this good security?
