Title: Works great, breaks soon.
Review: I purchased four of these in 2002. All were carefully installed (the door must latch much be adjusted if required such that the deadbolt moves easily in and out of its strike) and are in light residential use - probably a max of 500 cycles on the most frequently used lock.As of October 2004 two have failed; one mechanically (motor turns but deadbolt does not move) one electronically (no response to keypad or programming button).These *are* convenient - but at a minimum I'd install two of these if there is any likelihood that you intend to use them in a keyless mode - that way you will still be able to use the other if one fails.----------Update: as of 04/09 all four have failed ... two electronically, two mechanically.
