The random key (rkey) first generates a random number between 1 and 200000 which is key to generating the actual key (key), After the rkey generation is done, The keys generate a random number between 0 and the number the rkey generated, And finally the main code (ultkey) is generated by adding up all they keys together. The ultkey is the actual code you have to put in. There are a total of 5 rkeys, Each for the 5 keys to make a total of a million possibilities of what the actual key might be. And this isnt the only layer of the lock, There are 2 more to get through for a total of 3 layers of security, Each with a randomly generated code each time, Each time you try to get in isnt the same.
Dont let the Scratch Cat fool you, Theres an actual code system inside.
