Hello Lemmy!
I have moved to a walkable area and no longer need to have my car keys on me all the time. My landlord has put in a crappy 4 digit combination style door lock, but said I could change it.
What is the best kind of keyless door lock that I can use instead? Ideally one with decent enough security to be as good or better than a key?
Thanks for your input!
Ah, ok, so there’s only 4 numbers to work with, and the code has to be a length of 4 as well? Can numbers not be repeated? It should be 4^4 I believe, because you can do 1-1-1-1, 1-1-1-2 etc.
Assuming the numbers go from 0 to 9 (those included) and can be repeated, it must be 10 * 10 * 10 * 10 = 10000 combinations :-)
Their assumption is that it is four digits long and the person knows which four digits but not the order.
Ah, ok. So it’s not just trying all combinations. The numbers could be worn out from pressing over and over, for example.
