Create a random door code for your front door. This HTML form does not save any data. Choose a code style and then use the PDF button to save a copy.
The lock has five buttons stacked top to bottom - button 1 is the top and 5 is the bottom. Your code is a short sequence of presses. After entering it, you turn the knob/lever to open the door.
Two simple rules:
A dot means "then." Two numbers joined together mean press those buttons at the same time.
Optional - fill these in to personalize the PDF before generating.
