It’s a math thing it’s 4 factorial

However, if you take away all but the clean ones (4 of them) then 256 is correct (4x4x4x4…or 4 to the 4th power).

But in what sequence.

Nope... You're repeating numbers in your scenario...

5040 combinations without repeating a number

Getting back to the original concern, when we moved in (2013) there was a comment made about a "universal" code programmed into the MVP openers so the trades could get into the houses to work. In any case we deleted all codes and added our own. I have replaced one opener with a Chamberlin unit that uses a rolling code system and will shortly be replacing the other.

But is your keypad clean or dirty???

Jus lost a stand-up. R.I.P.

At least 24 more times...

Most keypads will lock up if you try too many times. Keypads are safe.

If there were only 24 everyone would be playing the 4 digit lottery.

Lets face it..no thief is going to mess around with the clean numbers on your keypad. They will simply go to your front door and pu**** in. Our doors are not the strongest and the locksets and hinges arent reinforced.

Keys
 

This is a little off the subject but helpful anyway. A few years ago I came home to find all the power out in the area. The only way into the house was a key we had hidden outside. Some of our neighbors couldn’t get in their homes because they didn’t have a key. I now keep a house key in all of our cars.
