Resetting the Code/Combination From a Lost Code
1. Removing Lock From Door
Remove both the outside unit assembly (a) and the inside unit
assembly (b) (see gure 1). Reverse procedures from sections E and F of
this manual.
2. Removing Combination Chamber Assembly
Carefully remove the base plate of outside unit assembly (a) by
removing the 2 Phillips screws (one screw may be found under an
inspection sticker).
Remove the combination chamber assembly (b) from the base plate by
removing the 2 Phillips screws (c) (see gure 2).
Remove the 3-sided dust cover (d) to fully expose the chamber by
removing 2 small Phillips screws (e) (see gure 3). May be 1 screw (x) in
newer models.
3. Resetting and Recovery of Current Code
To reset the code gears (a), each one of the 5 “L” shaped legs (b) of the
unlocking slide (c) must engage snugly with the corresponding code
gear pocket (d) next to it (see gure 4).
Position the chamber in one hand, as shown (see gure 5). Hold
chamber by the top screw tab (e) and bottom screw tab (f).
Rotate the reset cam (g) back toward you with your nger, towards the
key stems (h) as far as it will go and then release. Now look at the code
gears (a) and the unlocking slide (c). Note that some or all 5 of the code
gear pockets (d) are rotated away from the “L” shaped legs (b) as if out of
alignment. Typically each code gear pocket will be at a slightly dierent
distance compared to the other.
Note: There is no way to determine a forgotten, unknown or lost combina-
tion code from the front or outside of the lock. However, it can be reset and
recovered or reset and changed to a new code by following the steps in this
section.
Warning: Since this procedure is of a technical nature, only technically
trained personnel in the lock and hardware eld should undertake this
operation. For further assistance, call the Kaba Access Control technical
support line at 800-849-TECH (8324) or 336-725-1331 between 8AM and
5PM Eastern Standard Time, Monday through Friday (except holidays).
