My Weiser electronic lock's keypad stopped working about 6 months after I got it. Having no receipt and not being keen on replacing it with another cheap membrane keypad, I figured I'd replace it with something more durable.

Materials needed :
6 momentary switches
1 enclosure
1 6 wire cable
1 6 connector header socket
extra wire

Tools needed :
hotglue gun
soldering iron
drill with bits
wire cutters

Step 1: Map Out Your Keypad

You need to figure out what each membrane button on the keypad actually does. I started with the lock button and listed the two wires (out of the six) that each button closed. For me, it was :

Lock : 1 and 4
7/8 : 2 and 5
9/0 : 5 and 4
1/2 : 2 and 1
3/4 : 3 and 2
5/6 : 4 and 3

Unless you have the exact same lock as me, your mileage may vary. Trace them out for yourself to make sure.
Great job! You should recess the switches into the door instead of putting them in a box attached to the door. Would make for a sleeker appearance. OR at least use a thinner box.
Those are excellent suggestions. The box I used was the thinnest that would accommodate the switches available to me on short notice. I could have recessed into the door, certainly, but I didn't want to make holes that large in the door. While I'm happy with the end result, I would encourage someone who wants to replace their keypad to consider these suggestions.
I really lucked out on one these locks.. I found a <strong>Brand New</strong> (it wasn't opened) one at a garage sale for <strong>.10$!</strong><br/>
is that 10 cents or 10 dollars? I'm confused lol
10 cents!! (Canadian) lol
it says .10 dollars, so it's probably 10c
Yeah, I think they are fantastic. We have pets and it is really nice to be able to call up a friend and give them a code over the phone or whatever. I just didn't have any luck with the keypad - everything else was great.
Absolutely fantastic. I love it. Heck, I want one. I want the lock I buy to break, so I can be forced to make this. It reminds me of the old-school elevator buttons in the older buildings.
Thanks :) It seems to work really well thus far (it has been in place for all of 24 hours now) - much more satisfying to push its buttons then the original one. So far no false presses, either, which used to happen with the original. Happy so far!
