Operating Instructions: Changing the Combination
This section details the process for both opening the safe and subsequently changing its combination using the YOSEC L-1 Change Key. These instructions are based on standard procedures for La Gard 3-wheel combination locks.
Part 1: Opening the Safe Using the Opening Index
Before changing the combination, the safe must be opened using its current combination. If the safe comes with a factory-set combination, use that. For a previously set combination, use the known code.
- Dialing the Combination:
- Turn the dial to the LEFT and pass the first number of the combination four times, stopping on the first number on the fifth pass.
- Turn the dial to the RIGHT and pass the second number two times, stopping on the second number on the third pass.
- Turn the dial to the LEFT and pass the third number one time, stopping on the third number on the second pass.
- Opening the Lock: Turn the dial to the RIGHT until the dial stops. The combination lock bolt will retract, and the safe may be opened.
Note: For a previously set combination, ensure the lock is fully retracted (open) before changing. Verify the dial stops between 90 and 100 on the OPENING index.
Part 2: Changing the Combination on the Changing Index
This procedure requires the YOSEC L-1 Change Key. Ensure the safe door is open and the lock bolt is retracted.

- Prepare for Change:
- With the safe door open and the lock bolt retracted, dial the existing combination to the CHANGING INDEX. For example, if the combination is 10-20-30, dial 10-20-30 to the CHANGING INDEX.
- Stop on the third number (e.g., 30) on the CHANGING INDEX.
- Insert Change Key: Locate the keyhole on the back of the lock. Insert the YOSEC L-1 Change Key into the keyhole. If the change key does not go in, the wheels are not lined up. Re-dial the combination to the CHANGING INDEX and try again.
- Turn Change Key: Turn the Change Key to the RIGHT approximately one-quarter turn. Leave the key in the lock.
- Set New Combination: Select a new combination. Avoid numbers between 0 and 20 for the last number of the combination (forbidden zone).
- Using the CHANGING INDEX, turn the dial to the LEFT and pass the first number of your new combination four times, stopping on the first number on the fifth pass.
- Turn the dial to the RIGHT and pass the second number two times, stopping on the second number on the third pass.
- Turn the dial to the LEFT and pass the third number one time, stopping on the third number on the second pass.
- Remove Change Key: Turn the Change Key to the LEFT until it stops. Remove the key.
- Test New Combination: Completely dial the new combination to the OPENING INDEX several times to ensure it works correctly before closing the safe door.
- Secure the Safe: After successfully changing and testing the new combination, retract the lock bolt several times before shutting and locking the vault or safe door.

Troubleshooting

- Ensure the change key was turned to the RIGHT, left in place during dialing, and then turned to the LEFT and removed correctly.
- Test the new combination multiple times to the OPENING INDEX with the safe door open before closing.
- Confirm that the last number of the new combination is not within the "forbidden zone" (typically 0-20).
