What if … 
…accidentally the cam got moved before installation? 

 
As long as the code has not been changed with the change key, the lock can be prepared for 
mounting following the steps below: 

1.  Hold the lock so that you look at the cover and the bolt is to the right. 
2.  Turn the cam clockwise minimum 4 complete turns and stop when the cam is lined up as 

shown in figure 1.  

 

Turn cam counterclockwise until lock opens.  The cam should be lined up with the “LOCK 
OPEN” line on the cover (see figure 2).
