Oli mailed me enthusiastically with a trick he heard from a locksmith
\nwhen I was in Barcelona.<\/p>\n

Unfortunately it is not a trick to open an EVVA 3KS lock. I believe
\nthe 3KS lock is one of the most decent locks ever made. Virtually
\nimpossible to open without damaging it, hard to drill and keys that
\nare very secure against unauthorized duplication.<\/p>\n

And EVVA is improving the design of this lock all the time.
\nThe proof of that statement is at the end of this posting ….<\/p>\n

The story that came to me was that you could add an extra layer of
\n‘master key’ protection to a standard 3KS lock by removing some
\nmaterial of the key.<\/p>\n

Normally you can only withdraw a working key after full rotation of the
\nkey in the lock. However, if you remove the top layer of one side of
\nthe key, you can remove it after 180 degree rotation. This will keep the
\nlock in a very odd state. The lock is still locked, yet will not allow
\na non modified key entrance to the lock. Only a key that is filed flat
\non one side will be allowed entrance and can open (or close) the lock
\nwhen it is in this ‘180 degree state’.<\/p>\n

At first this might not sound like a big deal. But it is a nice way
\nfor a store owner to lock (or open) his shop and he is the only one
\nthat can operate the lock. Or at least it will give him the power to
\ndeny otherwise valid keys entry to the lock. I would not call this a
\nbug or design error, but a nice feature.<\/p>\n

Here are some of the pictures Oli send me:<\/p>\n

Step 1) The EVVA 3KS lock and the modified key. Normally there is a ‘wave’<\/p>\n

on the top and bottom of the sides of the key. But now on
\none side this ‘wave’ is completely filed down.<\/p>\n

<\/p>\n

Step 2) Key with flat filed part is inserted in the lock, flat side
\nfacing downward. Take a close look at the black ‘follower’ that is in
\nthe down position on this picture.<\/p>\n

<\/p>\n

Step 3) Turn Key 180 degrees. You can see the black follower now is
\naimed upwards.<\/p>\n

<\/p>\n

Step 4) Remove key. Now the flat side is on the top side. In this
\nstate, original, non-modified keys can not be inserted into the lock.
\nOnly a key that is flat on one side can be inserted and operate the lock.<\/p>\n

<\/p>\n

I was glad to receive the images from Oli and decided to shoot some
\nvideo on this subject. I took one of my new EVVA 3KS locks and started
\nto file away on the key. However, no matter what I tried I could not
\nremove my key after 180 degrees. I did try many things, yet the lock I
\nhave can not be opened this way. So I will call my contact at EVVA
\ntomorrow and ask his opinion on this. My guess is they improved the
\nlock in the meanwhile and it is no longer possible on newer models.<\/p>\n

I wanted to shoot some photos of the internals of a 3KS lock to show
\nyou why there is a relief profile on the sides of the key and why this
\ntrick works on the older generation 3KS locks. Unfortunately my
\ndigital photo camera is not available till the end of this week. So I
\ncould not shoot the images yet. Will do so at the end of the week.<\/p>\n
