The Simplex 900 Series by Kaba Access Control is a pushbutton mechanical lock that has been produced for many years. It is available in a number of configurations including deadbolt and deadlocking latch. These pushbutton locks can be programmed to unlock when pressing one button or a sequence of up to all five buttons. In addition, two or more buttons can be pressed at the same time. However, each button can only be used once in a combination. The 900 Series has been installed mainly in light commercial and residential applications.

Easily identifiable, the Simplex 900 Series locks are equipped with five exterior pushbuttons arranged in a circular pattern. The numbers are indicated by roman numerals (I, II, III, IV V) positioned around the pushbuttons on the faceplate. The outside thumbturn, which is used to retract and to extend the latch or bolt, is located either above or below the pushbuttons depending upon the hand of the door.

Rotating the outside thumbturn clockwise retracts the latch or bolt once the correct combination has been entered. 900 Series locks are equipped with a friction clutch mechanism that prevents forced rotation of the outside thumbturn from retracting the latch or bolt. Should the thumbturn be force rotated, it can be returned to the operating position without damaging the lock by turning the thumbturn until it snaps back into place.

When the outside thumbturn is rotated counterclockwise, the combination chamber is cleared and ready for the combination to be entered. If the 900 Series is a deadbolt configuration, rotating the outside thumbturn counterclockwise also extends the bolt. The outside thumbturn is spring-loaded and will turn back to the vertical position once released.

Note: The Simplex1000 and 5000 Series evolved from the 900 Series mechanical pushbutton locks using its mechanical chamber. Although the arrangement of the pushbuttons is different, the pushbutton positions in the 1000/5000 series are vertical, the combination chambers that are the locking mechanisms are programmed using similar instructions.

Step 2 . Enter the combination. If the combination is unknown, first try the factory default combination. Momentarily press buttons II and IV simultaneously, then momentarily press button III. There should be a slight resistance when each button is pressed. If that does not work because the combination has been changed, see instructions for clearing a lost combination.

Simplex 900 Series locks are equipped with a screw on the top or bottom of the lock housing located on the interior side of the door. Behind this screw is the internal lockout slide that can reset the combination chamber once the correct combination has been entered.

Step 4 . Slide the long end of the hex wrench into the opening and press the internal lockout slide. There should be a slight click when the slide moves. Do not force the slide to move.

Step 7 . Enter the new combination. A slight click should be heard when each button is pressed. Remember that each button can only be used once, and two or more buttons can be pressed simultaneously.

Try to retract the latch or bolt just by rotating the outside thumbturn counterclockwise, then clockwise. If the lock unlocks, the combination has been set to a zero code. Repeat steps 3 through 8 to set the desired combination.

Step 4 . Look at the locations of the five code gear pockets. If any code gear pocket is at the shearline, it can be ignored as it is in the open position. Look at the code gears whose pockets are not in the open position (shear line).

Step 5 . Find the code gear whose pocket is the farthest away from the open position. If two gear pockets are in similar positions, they were probably pressed at the same time when the combination was originally set.

Step 6 . Depress the key stem(s) that controls the code gear(s) that is the farthest away from the open position. Release the code stem(s). The code gear pocket(s) should move toward the open position. Repeat Step 6 until all of the code gears pockets line up in the open position.

Realigning the code gears takes some practice. If a code gear pocket passes the foot of the unlocking slide, the chamber must be reset and decoding must be started over. A good way to learn is to use a code chamber with a known combination and see how pushing the key stems as if you were entering the combination causes the code gears to move and line up with the pocket aligned to the foot of the unlocking slide.

Step 9 . Kaba Access recommends entering the 3 and 5 simultaneously, then entering 4, releasing each key stem after it has been depressed. This is the factory default code of 2 and 4, then 3, if the code was being entered using the pushbuttons.

Step 11 . Reassemble the combination chamber by attaching the three-sided dust cover. Make sure the plate joints on each end slide through the slots in the dust cover. Stake the plate joints to keep the dust cover from disengaging.

When setting the new combination, follow the above instructions for changing a known combination and use the factory default code combination of 2 and 4 simultaneously, then 3, as the known combination.
