The programming instructions are just fine. But you have to take the time to read them and understand the pattern of logic in all of those keypad entries. Here's a clue (I put 0000 as the user code, as this is the factory default when you first get the lock): Think of the "Kwikset" button as "ENTER". I will call it that from here on. Think of the PC (programming code) as a "key" to let you into the space where special "boss only" functions can happen. Every time you want to do something other than unlocking the door, you need to use your "key" to be able to do it. When you enter the "key" (by pressing 0000 ENTER), you've entered the "control room", and then you can do "boss only" stuff. Each of the ten "boss only" special functions has a number. There are ten buttons on the keypad and each on has a special function. These functions are: 0 - RESTORE DEFAULT ORIGINAL FACTORY SETTINGS (only AFTER you have hit the "reset" button.*) 1 - ADD A USER CODE 2 - DELETE A USER CODE 3 - DELETE ALL USER CODES 4 - CHANGE YOUR PROGRAMMING CODE 5 - ENABLE/DISABLE AUTO-LOCK** 6 - CHANGE AUTOLOCK TIME DELAY 7 - MUTE/UNMUTE LOCK** 8 - ENABLE/DISABLE ALL OF THE USER CODES** 9 - ADD A "ONE TIME ONLY" USER CODE Now, pay attention to the pattern of keypad commands. The pattern is: 0000 + ENTER + [ special function number ] + ENTER This is the pattern to engage any of the ten special functions (see list above). If the function involves a number (user code), then you add + [the number] + ENTER after the pattern above * Resetting to factory/default settings begins with pressing the tiny reset button, which is on the inside/back of the lock, underneath the removable cover that you just lift up and lean toward you to release. It's in a little hole, so you'll need a ballpoint pen, un-bent paperclip, or some other small thing that can fit into the tiny hole. When you first press it, there is a beep. DON'T RELEASE IT, keep pressing and wait . . . quite a long time . . . until you hear THREE beeps. Then it's reset. ** All of these "enable/disable" functions can be tricky, because it's not very clear if you have enabled or disabled when you key in the sequence. I noticed that the ENTER button illuminates green for enabled and red for disabled. FINALLY . . . there seem to be some really sensitive parameters with this little unit, when it comes to TIMING. If you key things in too fast or too soon, or too slowly or too late . . . it doesn't work. I have three of these locks, and they are all persnickety about the timing, but one of them is EXTREMELY persnickety. This leads to some frustration, when using a special function FAILS again and again. Until it finally SUCCEEDS!
