Demo

Practice on the demo to see how digital locks work:

1. Click "C" (to clear)
   
2. Click "Y02" (the practice code)
   
3. Click on the knob (to turn)

See the congratulations message! It's simple, easy, and fast,
if you know the code!  Order does not matter. Click "C" any time to clear the buttons and begin again.

Now, try it for real. HINT: To make this easy, we have set the secret code to only 3 numbers and/or letters. (The real lock takes up to 5.)

Please note:

1. Actual locks are programmed with only 1 code, which can be changed in just a few minutes.
2. Begin each attempt to open by clicking "C". This clears all the tumblers in the lock from previous attempts.
