Wireless Keypads are security keypads and should be programmed to ONE opener.
The Wireless Keypad comes with one 9V Lithium battery, instructions, and two keys. A wireless signal is transmitted when a valid 4-digit PIN and the # key is pressed. A long tone will sound. The keypad backlight will illuminate for 15 seconds when any key is pressed. If an invalid PIN or partial PIN is accidentally entered, an error tone will sound. The Wireless Keypad is compatible with all Chamberlain Security+2.0 openers.
