• Listing omits max range

The Chamberlain Genuine Universal myQ Wireless Garage is an authentic factory unit designated under model number CHU48. Manufactured directly by Chamberlain Group, this peripheral is engineered for homeowners who prioritize genuine OEM electronic integration over third-party alternatives. It operates alongside openers manufactured after 1993 that feature operational safety reversing sensors mounted near the garage floor. The device provides keyless walk-in access using a personalized four-digit security code, eliminating the need to carry physical brass keys or clip-on transmitters during outdoor activities.

From an architectural standpoint, the chamberlain chu48 universal keypad incorporates high-grade rolling code encryption designed to prevent code grabbing by nearby interceptors. For users paired with Chamberlain, LiftMaster, or Craftsman powerheads built after 1997, the logic board unlocks two critical software utilities: temporary PIN generation and one-touch door closing. The temporary PIN mode lets homeowners program time-restricted numerical combinations for tradespeople or visiting guests without revealing the primary master code. The one-touch close function allows swift egress by pressing a dedicated close key, bypassing the requirement to re-enter the complete four-digit access sequence when exiting the my q garage perimeter.

Weighing 7 ounces with exterior dimensions measuring 1.24 by 2.89 by 4.97 inches, the CHU48 features a weather-resistant exterior housing molded in a clean white finish. The enclosure is sealed against rain, snow, and extreme seasonal temperatures. The product ships complete with mounting screws, a product setup guide, and a standard 9-volt alkaline battery, allowing immediate surface installation on exterior door jambs without routing low-voltage electrical wiring.

• Compatible with post-1993 openers equipped with functional optical safety sensors
• Enables temporary guest credentials and one-touch close for post-1997 Chamberlain, LiftMaster, and Craftsman units
• High-level encryption algorithm prevents signal duplication and interception
• Includes factory mounting hardware and a 9-volt alkaline battery

Best for: Large properties managing up to five doors

Pros

• Controls up to 5 devices

The 940EV-P2 Universal Chamberlain Garage Door Opener from Avisontek is engineered as a multi-device replacement peripheral capable of managing complex garage layouts. Unlike single-operator keypads, this radio-frequency console can register and command up to five independent garage door openers. It serves as a direct functional substitute for legacy Chamberlain and LiftMaster models including the 940EV, G940EV-P2, 940ESTD, 377LM, 977LM, 877MAX, and 878MAX, giving it immense versatility across residential installations housing varying opener generations.

The technical core of this 940ev-p2 chamberlain keypad relies on rolling code transmission across a rated maximum operational range of 164 feet. Each transmission triggers a pseudorandom algorithmic shift in the access code, blocking unauthorized signal grabbers. The interface features a 13-button physical array protected behind a vertical flip-up cover that shields the keys against solar degradation and freezing moisture. The buttons feature integrated glow-in-the-dark backlighting to ensure legible code entry during night cycles.

In practice, the keypad incorporates both master four-digit access codes and secondary temporary PINs for service personnel. The integrated one-touch close functionality operates under a strict timing window: once the primary authorization password is submitted, the single-press close action remains receptive for exactly 15 seconds. After that duration elapses, the circuit automatically locks, requiring full PIN re-entry to move the door. Installers must note that while the unit supports Chamberlain, LiftMaster, Craftsman, Genie, and Linear receivers, the listing explicitly notes it does not support Security+ 3.0 white learn buttons or vintage DIP-switch consoles.
