Do you know how to reprogram digital code?? kwikset 907 lock

I must have an old lock -- there is no square reprogram button. I must have an old lock -- there is no square reprogram button.

It's hard to say regarding how old yours is, but mine are over 3 years old. The reprogram button may not be readily marked as "Reprogram"... located on the non-keypad side of the lock below the batteries and kind of to the left side. On mine it is like a black square that has a depressible "soft" type center. Press it once and it gives off a beep. Once the beep stops, then press on the keypads on the other side to enter your code and press on the middle keypad (lock) once. Then, press your code again along with the lock button to see if it responds to push out the deadbolt as if it is going to lock the door. If you mess up, wait about five minutes and start over with pressing the reprogram button. It may take a few tries before you get it figured out to work.

Sometimes the batteries get jiggled loose, too, so if pressing the reprogram button does not result in a beep sound, then either your batteries are old or they are not making adequate solid connection (which happened to me a couple of times). What happened is that as soon as the poor connection made contact, a long beep sounded. This is where "figure it out" came into play by trying different variables to reprogram the key code or to get the existing one to work. As usual, waiting about five minutes for the unit to sort itself into "idle" I tackled it again with usual steps to success. If done wrong, the keypads will not respond with any sound, so have to wait thru to the idle period to try again.

Your unit probably has a reprogram button, but may be located in a different place. Oh, by the way, I just bought a new one this week and it has a "smart key." Pretty nifty. Put the smart key into the key lock where you'd insert the key for the deadbolt, and then put the key from another keypad lock you have ... poof, now I can use the same key for both keypad locks. Really ... uh ... smart. Of course, save the keys that you aren't using since you might want to change the locks again at some future date.
