Lathem has a new proximity badge door lock. Beyond low cost, benefits include door access control for up to 120 users with credit card size proximity badges or optional keychain fobs, simple user-installation on most existing interior doors, and stand-alone, battery-powered operation that doesn’t require a computer or external device to program or operate. It eliminates locksmith costs and the hassles of re-keying, and badges can be assigned to additional locks for multi-door control. Companies already using Lathem’s proximity time clock system can program their existing employee badges for the LX100. Using radio frequency technology, the LX100 instantly identifies proximity badges and keychain fobs to grant employees access. With four AA alkaline batteries, it operates for one year, or 4,000 uses depending on the door’s traffic.
