Schlage
Homeowners can control and monitor access to their property by housekeepers and other service people with E-Bolt, an electronically controlled deadbolt that can be programmed to accept only specific keys at specified times. E-Bolt records the date, time and key identity of each valid access. When a service person completes a job or is dismissed, his or her key is deactivated, eliminating the need to re-key or replace locks. The deadbolt meets or exceeds ANSI 2 requirements, the company says, and does not use pins, making the lock pickproof.
