You should be able to hold down the OK button (big circle button on the bottom of the screen) for 3-5 seconds and the numbers should switch from shuffled to sequential order. The numbers will show 123 456 789 etc. Holding it down again for 3-5 seconds to go back to PIN Genie mode where the numbers are shuffled.
To turn on PIN Crazy, make sure the PIN Crazy switch is switched on in the inside of the lock. Then you can activate PIN Crazy by going into the app and click Lock Settings – PIN Crazy.
In PIN Crazy mode, the numbers will shuffle every time a digit is entered not when the sequence of the whole code is entered (PIN Genie Mode).
