CPU Section Lock Replacement Instructions 

If you want to replace the CPU section lock with your own lock, use the provided parts and follow the instructions 
below. 

1.  Turn off and unplug the game. 

2.  Unlock and open the CPU section. 

3.  Insert the key into the lock and turn the key so that the cam protrudes to the right as shown in Figure 1.

4. 

Gently

 insert the provided Allen wrench into the small hole in the barrel of the lock and simultaneously pull the 

key upwards to release the cam and tumblers from the assembly.  See Figure 1. 

NOTE:  If you are having difficulty removing the tumblers, make sure the key is turned so that the cam 
is sticking out from the right side of the barrel and then make sure you are very gently inserting the 
Allen wrench into the hole in the barrel. 

5.  Loosen the nut around the barrel of the lock in order to remove the spacer, shim, and barrel from the game. 

6.  Install your replacement lock in the game and reinstall the spacer from the old lock.  We have provided a cam 

and an adapter (in the event that you are using a double D lock).  Depending on the lock you are using, you 
may also need to use the shim from the old lock in order to take up some of the extra space. 

7.  Close and lock the CPU section. 

8.  Plug in and turn on the game.
