For keypads exposed to rain and dust, compare IP65 and IP66 ratings, along with features such as sealed or epoxy-potted housings, backlit keys, and door or tamper inputs. For tampering concerns, look for stainless-steel or rugged aluminum housings, die-cast zinc construction, vandal-resistant faceplates, and built-in tamper detection.

Weatherproof keypads for digital locks typically connect to electric door hardware through Form C relay outputs, which can control devices such as electric strikes or magnetic locks, while door sensor and request-to-exit inputs support access-control functions. Many models use 12 to 24 volts AC or DC, with programming and user credentials stored in the keypad, while some proximity-enabled versions connect card readers and temporary access codes through the same keypad interface.

Mounting options include narrow-stile or mullion installation, single-gang back-box mounting, and surface installation, depending on the keypad design; choose a location and enclosure that support outdoor use and allow room for wiring. Most units accept 12 to 24 volts AC or DC and connect to lock or access-control circuits through relay outputs, with some models also supporting door sensors, egress inputs, tamper connections, or doorbell functions.

Choose PIN entry when users can share or remember codes, proximity access when you want card-based entry, or support for both when a site needs flexible access options. A dual-mode weatherproof keypad can support different user preferences, temporary credentials, and backup entry methods, while a PIN- or proximity-only model may simplify programming for a more focused installation.
