Q: How do I change the combination on a "Set-Your-Own" combination lock model #643D?A:
Here are the instructions for changing the combination on your model 643D lock. This lock is preset at the factory to operate at 0-0-0-0.
Note: Be sure to record your NEW combination as you are the only one that knows it! Note: The lock may only be reset when it is in the open position. If you do not recall the combination the lock is set to, you will not be able to reset the combination. |
