Mortice keys will fit in the Key Organiser as long as the length is shorter than 67mm (from the hole to the end of the key), and the hole on your key is greater than 4mm in diameter. There is a bit of play involved in setting up a mortice key in the Key Organiser, but it should work! Follow our guide to help you out:
1. Place the mortice key at the end of the stack.
2. Use both wave washers that comes with the Key Organiser - and place the key in between the two.
This set up is also useful for any other keys that doesn't have a flat surface - makes it easier to swivel in and out of the stack.
