I've got an office where a group of people need keys to the front
door. At the moment it's a normal euro lock cylinder, but I've been
told that people are getting spare keys cut so I don't have control of
the number of keys in circulation.

I'm considering changing the cylinder for one with a restricted keyway
pattern to prevent this. Does anyone have any recommendation for good
examples? I've heard of Mul-T-Lock, but I don't know if they are any
good, or if other types might be better.

I'm only trying to prevent casual copying: I don't think there is
anything malicious going on, so anything that high-street key cutters
can't duplicate is probably sufficient.

I can't help with the key, but it sounds as though a CCTV system might
be a wise investment if there isn't one already.

I've already got a CCTV system; and outside office hours there's a
shutter over the door and an alarm system.

But thanks for the recommendation: it's true that a front door lock
alone is not everything.

Just become acquainted with ABS locks - http://www.abs-secure.co.uk/

We have six of their locks and they seem to work fine. But so they
should - they are all new. They have a restricted copying program - and
the keys actually have magnets in them. Price not known!

They are still working fine after a few years.

They are about £30 each and you need the card to get keys cut.

They get a three star security rating without needing reinforced handles
like the yale ones do.

Mul T Lock BS TS007 3 Star Integrator Euro Cylinder can't be copied by
your local lock smith.

I have just bought several from lockandkey.co.uk

You can ring them up.

Any 'proper' locksmith can supply a Euro cylinder with security keys.
The key blank is only available to that particular locksmith, nobody
else can get the blank to cut the key. High street key cutter wouldn't
know where to start. The locksmith will only cut a spare key with
written authorisation from you.

Euro cylinder around £60 - £80, keys around £8.

Trust your local professional locksmith with regard to make or brand.

How is that worse than any other way in which a lock has been destroyed
in place? ABS point out that this means it is at least feasible to
unlock from inside whereas other makes seem to get so totally destroyed
you don't even have that option.

At the amateur theatre I used to be involved with, the locks were specially

Five years down the line, all keycutting shops carried them in stock.

A simple mechanical lock will have a key that can be copied, albeit at
expense.

There are some door entry systems that operate on the "catch" side
leaving the conventional key side still operable.

Just that for "secure locks" with limited supply of blanks tend to be
expensive, and blanks exclusive for a limited time, and of course also
expensive.

Worst one for me was a Humber Hawk gearbox.

I started by obtaining short lengths of mild steel in different sizes to
act as keepers. I remember having to stick a complete circle of needle
rollers to the inside of a bearing before refitting a shaft.

I know this isn't compatible with Eurolocks, but how about something
like this?

I'm looking for a simple mechanical lock really, as they seem more secure
with less chance to go wrong.

Mad IMO.

A simple mechanical lock will have a key that can be copied, albeit at
expense.

There are some door entry systems that operate on the "catch" side leaving
the conventional key side still operable.

And the last thing you need if there is a fire in the house etc
is to find that some arsehole has smashed the lock trying to
get in and that you can't get out and will have to die trying.

Just that for "secure locks" with limited supply of blanks tend to be
expensive, and blanks exclusive for a limited time, and of course also
expensive.

Yeah, a decent electronic lock fixes all that.

The OP was worried about unauthorised copying of keys. Wouldn't the
above technology be equally abused with the tag (keys) being scanned by
a mobile phone and then being reprogrammed on tags available on Ebay for
10s of pence?

Until the power goes off.

Yes, but there are plenty of others that are completely secure, particularly
ones where particular phones are allowed to open the door.

The better ones work fine when the power is off
because they have an internal battery.

Serious door entry systems have a password and a RFID key/fob/card.

The secure bit is that each key is unique and if a party copies one it's
obvious from records who has made the copy or is attributable to anyone
gaining entry.

It's also easy to bar a key if there is a nefarious copy becomes known.

And with more sophisticated systems that use a phone
instead of an RFID key/fob/card, they can't be copied.
