The Orbitkey comes with 2 wave washers, which helps with the tension, and keeps your keys in line - to make it easier to swivel a key in and out of the system.
There are several ways to fully utilise the wave washers in your Orbitkey. Here's a few tips that might help you!
Option 1: General use would be to place ONE washer at the end of your stack.
Option 2: When you have a key that doesn't have a flat surface (eg. key fobs, keys with plastic casings)
Option 3: Two key setup - we normally recommend using BOTH wave washers.
