step 1Purchase the lock and unpack it

I got mine on sale for $99 at Lowe's.

Remove it from the box and take a look at what's there. The construction of the lock is really great. Anywhere that could even remotely see any moisture is surrounded with rubber sleeving or a rubber o-ring. The lock has 3 basic parts:

outside portion: This portion has a regular key cylinder, a knob for the deadbolt similar to what you normally see inside of a house, and a keypad for entering the code.

inside portion: This portion has a knob to operate the deadbolt, a housing for a 9v battery, and a switch to tell the electronics in the front of the lock when the lock is in use.

deadbolt mechanism: This portion is similar to any other deadbolt on the market.

Thanks for the info! I'm looking at hooking up the motor leads to a small 9v relay which in turn would be hooked up to a wireless DSC home security contact. The N/C or N/O trigger can than be used to disarm my alarm using the keypad on the Schlage. No need to type the same code when getting in the house!

okay, so i have a couple questions about the lock itself. i see the numbers thew key hole and what not. so you can enter a code to get in, unlock it with the key, or with the arduinmo that you're adding?

I just found out Arduino/X10 communication is fairly simple and straightforward. I may take some time and interface an X10 remote with this. Good idea!
