3 builders told me that that wasn't true

The Linear garage door openers, in most recently built homes, can use 6 digits. Read the manuals that came with your home and you can easily reprogram the keypad. It takes less than 30 seconds.

24 is correct if, according to the OP, the 4 (clean) buttons to use were known.

That was the point - if you clean the buttons, the ones to use are now unclear bringing the combinations back up to 10,000

Its 24 if you do not repeat any numbers. 4*3*2*2 If you repeat numbers it is 4*4*4*4

With three clean builders, you will only have six combinations.

24 is still a good 10 minutes and quite frankly there isn't much in my house someone should be able to steal to make money to support their drug habit unless they're going after a couple of power tools that are worth 20 bucks from harbor freight, I would love them to rip something off like old furniture cuz you would probably cost me a hundred bucks to get it out of the house

The universe of potential numbers is the 4 clean numbers, not the other dirty numbers. 4*4*4*4=256

There are 10,000 codes. I think we’re safe. 👍

Nope. 24 possible codes when the four numbers are known.

[frank1975]

Your right!!! Four digit code would thousands of combinations.

Only 24 if you know the 4 numbers due to pad being different on just those 4 numbers!

This reminds me of a Seinfeld episode. The show about nothing. Lol

Depends on how many buttons are clean. If 4 digit code and 4 are clean then permutations are correct since you’re not using a repeated number

But he didn't know the sequence. It would have taken someone quite a while to enter.
