Chamberlain 940CB Security and Wireless Keypad
The wireless keyless entry pad from Chamberlain allows secure, coded access to your garage without a remote control or keys, just by entering the private 4-digit security code you determine.  Just like the rolling code in your remote control, the keyless entry transmits a new code with every use, one of over 100 billion, never to be repeated.  Also has the ability to be programmed for a temporary password.  This model mounts easily on the garage door jamb without any wiring or hardware required.  Illuminated for nighttime use.  Only for use with Chamberlain Security+ garage door openers.
