I need to reset the combination on my onguard 8030 doberman series lock
1. Open the lock with the factory preset combination of 0005.
2. Find the tab on the end of the part of the locking mechanism that has the numbers.
Combination Reset Tab
3. Flip the tab up (with the combination set to the open combination). When you flip the tab up, you disengage the number dials from the tumblers, so that you can reset the combination without changing the position of the tumblers.
4. Change the combination to the desired combination.
5. Flip the tab back down. The dials are now re-engaged with the tumblers.
