Keri Systems TM-20XMS Keri Key 2-Button Transmitter with MS Insert

Make secure, convenient entry the default with the Keri Systems TM-20XMS Keri Key 2-Button key fob transmitter. Built for gated communities, parking facilities and enterprise access control, this compact RF transmitter gives authorized users quick, hands-free control of gates and barriers from up to 295 ft (90 m), reducing vehicle wait times and improving traffic flow. The two-button, two-channel design lets a single fob operate two separate receivers—ideal for sites with multiple entrances or mixed-use facilities.

Beyond remote gate control, the TM-20XMS supports an MS proximity insert so the same key fob can also present to proximity readers for doors and parking access, simplifying credential management and improving operational efficiency. The transmitter runs on an easy-to-replace CR2032 coin battery and is housed in a durable, weather-resistant enclosure with noise reduction circuitry for reliable performance in real-world conditions. With built-in anti-cloning protections you get strong security for your access control, surveillance and monitoring needs.
