Costway offers this Keyless Electronic/Code Digital Door Lock in Chromium for $46.95 with free shipping. That's tied with last week's mention and the lowest price we could find by $2. This weather-resistant lock stores up to 10 codes and fits doors 1.4" to 2" thick. Features include stainless steel construction, a 0.3" lock rod, backlit keypad, and low-battery warning. Four AAA batteries are required, but not included.

Update: As a reader found, Global Cyber Mart via Amazon has a similar model for $42 with free shipping.
