Kaba-Simplex 1000 Series - Alpha Locksmith

In this review I will discuss another mechanical pushbutton lock by Kaba-Simplex: 1000 Series. As in my other lock reviews, I will discuss this lock in the light of my six standards of quality as outlined in my first lock review.

With respect to affordability this lock receives 3/5. This is not an inexpensive lock. It comes in four finishes: satin chrome, antique brass, bright brass, and bright chrome. In the field though, one typically only sees this lock in either satin chrome or bright brass. The former starts at $540.48 and the latter starts at $638.88. However, because this lock is fully mechanical, it eliminates the labor and cost associated with installing batteries; not to mention the cost and aggravation of issuing, controlling, and collecting keys, cards, and fobs.

With respect to strength this lock receives 4/5. With a heavy duty cylindrical lock housing, a cast front housing, cast knobs/levers, a unified trim plate, and solid metal pushbuttons, this lock is both weather and vandal resistant. It is fastened to the door using two 8-32 x 2-1/2″ screws and a reinforcing plate. The strike plate is fastened to the jam using 8-32 x 3/4″ screws. (If installing this lock on a door with a wooden jam, the author recommends that 3″ screws be used to fasten the strike plate.) That said, this lock does not come with a vandal-proof clutch; but more importantly, models manufactured prior to September 19, 2010 can be bypassed using a rare-earth magnet.

With respect to aesthetics this lock receives 3.5/5. Though this lock comes with either a lever or knob and in a number of attractive finishes, it is quite bulky. However, given that it is used in retail locations, hospitals, factories, schools, and government sites, among others, this is rarely, if ever, an issue.

With respect to installability this lock receives 4/5. As far as mechanical pushbutton locks go, this one is very easy to install. All that is needed to install this lock on a door without ASA 161 door preparation is a variable speed electric drill, an awl (or centre punch), a 2-1/8″ hole saw with pilot drill, a 1″ hole saw with pilot drill, a 1/4″ drill bit, a 1″ wood chisel (for wooden door installations), a hammer, a phillips head screwdriver, a small flat blade screwdriver, and a pair of pliers (for models with a passage function). Most doors come prepped to accommodate this lock however, so in most cases all that is required to install this lock is two 1/4″ holes for the mounting screws and one 1″ hole for the combination change plug. For models that come with a passage feature (i.e. 1031 and 1041) and for the model that comes with a lockout feature, an additional 1″ hole must be drilled for the thumbturn or key operated passage adaptor and key operated lockout activator, respectively.

With respect to recombinability this lock receives 4/5. This lock comes from the factory with a single access code that is quick and easy to change. It does not need to be removed from the door for the code to be changed. All that is required is the DF-59 control key and spanner wrench, both of which are shipped with the lock. For complete instructions on how to change the code, go here and click on “Documents”.

With respect to pick and bump resistance this lock receives 2.5/5. The models that come with a key override feature (i.e. 1021 and 1041) can be ordered with your choice of either a small or large format interchangeable core, and are therefore, depending on the type of core chosen, vulnerable to either bumping and/or picking attacks. And because the locking device on this lock is a latch, it is also vulnerable to slipping attacks, but only if improperly installed.
