Specifications

deadbolts now use this innovative
piece of equipment to protect against
probing.
I did not use the smash attack on
the MIWA lock, but it would have
resisted the attack.
Medeco Maxum
Deadbolt Attack
The Medeco Maxum with Key
Keeper incorporates all the previous
High Security features with
additional hardened steel inserts to
thwart drilling and ball bearings to
protect the ends of the cap screws.
Photograph 12, shows the deadbolt
before installation. Note the anti-
probing features on the outside
cylinder at the right of the picture.
Photograph 13, shows the key
keeper with the cut down key with
the slot in the bottom. With this
deadbolt, it can be either a single
cylinder or a double cylinder model.
When the key thumb turn is inserted,
the unit is locked into the inside
cylinder and cannot be removed without turning the outside
cylinder a quarter turn either to the right or left. A very good
concept.
When the Medeco lock was assembled and installed on
the probing mount, the deadbolt bolt is protected from ice
pick probing and the mounting screws are covered with ball
bearings to prevent a drill attack.
After installing the Medeco, two small
chrome ball bearings are pounded into the
back of the lock just prior to putting on the
inside trim plate. How does one get the ball
bearings out? I have no good idea, but they
protect the screws from being backed out.
By this point, I felt like I had to uphold
the honor of The National Locksmith
Torture Test Lab by working the Medeco
over with a hammer (See Photograph 14).
As you can see, although I put my weight
into the job, I failed to compromise the
unit. A little marking is to be expected, but
blows which caved in the Defiant, left the
Medeco unscathed.
Conclusions:
All the locks, except the Defiant, were
impossible to pick. When all the locks and
their appropriate strikes are installed
correctly, using the extra long screws,
they will withstand a moderate kicking
attack. Using the tools that I usually
employ to open locked deadbolts, the
locks were safe. Was this a fair test? I
think so.
There is a place for High Security Locks, but there is also
a hefty price to pay. Most customers for deadbolts still like
to get the most they can for as little as possible. It is our job,
as security professionals to balance the level of protection
needed with what the customer can afford. With commercial
accounts, the best is the best and is the most expensive. Sell
the best.

the key, not in the lock.

Note the anti-pry metal shroud at the rear of the
outside cylinder housing.

at bottom of key. Once inserted, this key can only be
removed with outside key.
11. A successful probing opening
was accomplished on the MIWA
lock because the deadbolt
actuator is not protected by a
guard.
