Kerryville USA via eBay offers the SimpliciKey Wireless Electronic Door Lock, model no. SRCED-SN, for $99 plus $8 for shipping. That's the lowest total price we could find by $92, outside of the price below, although we saw it for $18 less last spring. It features a backlit alphanumeric keypad, up to 16 user codes, and blue LED for confirmation of locking/unlocking.
