To use a Master Lock push button (specifically referring to models like the 5422D & 5423D key safes), you interact with the buttons to set a combination. The reference material explains how to set the combination on these types of locks. Here's how you would set (or use) the combination:
- You'll need a recode tool or a small flathead screwdriver.
- You push and turn each of the buttons you want in your combination. According to the reference, as an example, you can set a combination like "2 4 6 8".
- When setting the combination you need to push and turn the button 180°.
In essence, setting the combination for the lock involves physically manipulating the buttons to your desired sequence. Once set, you would use that button sequence to open the lock.
