Skylink Garage Door Opener Keychain Remote Set (MK-1)

Enhance remote access to your garage while maintaining adequate security with the Skylink Garage Door Opener Keychain Remote Set. The set allows you to operate your garage door opener from either the indoor Smart Button or the 3-button keychain remote. The Smart Button replaces your traditional garage door opener wall button to receive wireless signals from the remote, which offers optional password-protection for greater safety and peace of mind. FEATURES: Smart Button replaces or parallels your traditional wall button. 3-button keychain transmitter operates up to 3 garage door openers. Easy Clip technology makes installation a breeze. GB series has highest compatibility (works with the latest garage door openers). Supports up to 15 remote controls (additional controls sold separately). Rolling Code Technology: Every time you press your remote transmitter to operate the garage door opener, a code is generated which is recognized by the receiver that in turn performs the desired function. With traditional garage door receivers, there is only one assigned code. Whenever the remote is pressed, it generates the same code, making it vulnerable to code grabbers who use electronic scanners to steal the code. With rolling code technology, each time the remote is used, it generates a different code which can only be recognized by a rolling code receiver. Even if an electronic scanner picks up the code, the next code will not be the same, and the receiver will not recognize the old code. As a result, garage door opener systems with rolling code technology are increasingly safe and secure.
