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
