Mega Code / Linear MCT-3 (DNT00089) 3-Channel Remote Transmitter - 5 Pack
The MCT-3 DNT00089 has three transmitter buttons; each sends a unique code when it's pressed. It works with most Linear 318 MHz wireless receivers, so you can use one button to open a secured access gate, one for a garage door and the final button for another garage door. Layered security is what it's all about, and this transmitter can help you protect nearly any space. The Linear MCT-3 takes two CR-2032 batteries, which are easy to install, and programming is so simple that anyone can do it.
