Changing the code on a Master Lock key box, specifically the Master Lock 5401 model, involves a few key steps to ensure the new combination is correctly set and functional. The process emphasizes verifying the code multiple times before locking the unit to avoid issues.
Here's a breakdown of the process, based on the provided reference:
-
Open the Key Box: Begin by opening the key box using the existing combination.
-
Set New Combination: Change your combination according to the master lock instructions.
-
Verification:
- Check Multiple Times: Crucially, check the new code several times before locking the unit. This step is emphasized to avoid locking the key box with an incorrect or forgotten combination.
- Door Position: Ensure the door is in the correct position during the code-changing process, as it might affect the mechanism.
-
Locking the Unit: Once you've verified the code multiple times and are confident it's correct, proceed to lock the unit.
Failing to verify the code can lead to the key box being locked with an unknown combination, rendering it inaccessible. This is why the instruction emphasizes repetition during the verification phase.
