Wireless Keypad

A wireless keypad is a weatherproof, battery-powered numeric pad that mounts on the exterior wall or door frame beside the garage door. A user presses their PIN and the Enter key; the keypad transmits a coded radio signal to the opener receiver, which validates it and triggers the door to move. No handheld remote is needed. This makes the keypad useful for people who prefer not to carry a remote, for children who need garage access independently, and for service workers who need temporary access.

How it pairs with the opener:

Like a garage door remote, a wireless keypad pairs to the opener through the learn button on the motor head. You press the learn button, enter the desired PIN on the keypad, then press Enter. The opener's logic board stores the PIN. Most modern keypads use rolling code encryption, meaning the underlying radio code changes after each use even though the PIN stays the same. Pressing the same PIN twice sends two different radio codes, preventing replay attacks.

PIN options:

Standard keypads support one or two permanent PINs. Many current models from major brands (LiftMaster, Chamberlain, Genie) also support temporary PINs that expire after a set number of uses or a set time window. A homeowner can give a plumber a 4-digit code valid only for that day, then let it expire without changing the main PIN.

Placement and installation:

The keypad mounts at a comfortable reach height, typically 48 to 60 inches from the floor, to one side of the door opening. It attaches with two screws and is powered by a standard 9-volt battery or AA cells depending on the model. Battery life with normal use varies by model; most manufacturers target at least one year per set of batteries.

On doors without an opener, a wireless keypad is not applicable. For those situations, a traditional keyed lock cylinder in the door handle is the manual alternative.
