The right garage door opener keypad is the one that matches the opener already on your ceiling. Start with its model number, manufacturing date, and radio system before comparing covers, backlights, or guest codes. Two keypads can look nearly identical while speaking different electronic languages.
For compatible Chamberlain, LiftMaster, and Craftsman systems, the Chamberlain G940EV-P2 is a straightforward option. For Genie Intellicode openers, the Genie GK-R is the more direct match. These recommendations compare documented specifications and compatibility rather than claiming hands-on testing or a universal winner.
Garage door opener keypads to compare
Chamberlain G940EV-P2 for compatible Chamberlain-family openers
The Chamberlain G940EV-P2 uses a four-digit access code and has a hinged weather cover. Chamberlain lists support for green, orange/red, purple, and yellow Learn buttons and the corresponding Billion Code, Security+, and Security+ 2.0 systems. Its compatibility guidance covers appropriate Chamberlain residential openers made after 1993 with functioning photoelectric safety sensors, plus many LiftMaster and Craftsman models.
A temporary PIN can provide limited access for a guest or delivery. The manufacturer excludes Craftsman Series 200, so a familiar brand name alone is insufficient. Check the exact opener against the compatibility chart before ordering.
Best fit: replacing a basic keypad on a verified compatible system. Trade-off: this is a conventional wireless access keypad; buying it does not by itself add a camera, an activity log, or smartphone control. The linked offer is the gray, single-keypad G940EV-P2 variant, also described as 940EV-P2 in the listing title.

Genie GK-R for Genie Intellicode systems
The white Genie GK-R is designed for Genie Intellicode garage door openers. The exact product listing describes compatibility with Intellicode-equipped Genie models manufactured since 1995, operation of up to three compatible doors, a backlit number pad, a flip-up cover, and a temporary PIN feature. It is a useful candidate for a household with several compatible Genie openers.
Genie’s GK support page explicitly groups GK-R with parts 37224R and 37332R. It confirms two AAA batteries and Auto-Seek communication at 315 and 390 MHz. These details help distinguish the original model from similarly named replacement products.
Best fit: a verified Genie Intellicode installation, especially when one outdoor keypad needs to serve multiple doors. Trade-off: the GK-R is not a universal keypad for every garage opener. Check its programming instructions for the particular motor unit, and do not assume that a newer GK2 keypad or an unbranded replacement has identical features.
Make a compatibility checklist before buying
A photo of the existing keypad can help identify its layout, but the motor unit is the better starting point. Record the following without opening electrical compartments or disturbing wiring:
- Manufacturer and complete opener model: copy the full label, including letters and suffixes.
- Manufacturing date: use the opener’s label rather than the year the house was built.
- Learn-button color or radio-system name: these narrow down compatible accessories when the manufacturer uses them in its chart.
- Existing external receiver: if one has been added, its compatibility can matter more than the original motor’s brand.
- Number of doors: check that every opener is supported, and understand how the keypad selects each door.
The word “universal” should prompt a closer look at the compatibility list. It does not mean every brand, generation, frequency, or commercial operator. Likewise, support for one Craftsman or Genie model does not prove support for another. If the label is unreadable, send clear photos of the motor and receiver to the manufacturer before buying a speculative replacement.
Choose access features you will actually use
A backlit keypad helps with evening access, while a cover keeps the buttons protected between uses. Consider whether the numbers are easy for everyone in the household to read and press. A neat-looking keypad mounted behind a gate or shrub is inconvenient even if it is electronically compatible.
Guest access deserves a separate check. A temporary PIN may expire after a set number of uses or a period of time, depending on the system. That is different from a permanent second code. Follow the model’s instructions, verify how the temporary code expires, and avoid handing out the household’s main PIN when a limited code will do.
One-button closing is also model-dependent. The 940EV family manual lists restrictions for older openers and external receivers. Confirm the feature on the supplied keypad and opener combination instead of assuming that every unit advertised under a related name behaves identically.
Plan installation before drilling
First pair and test the keypad according to its supplied instructions. Then try the intended mounting position before making holes. Leave room for the cover to open and for battery replacement. A successful test beside the motor is useful, but the intended outdoor location is where you need dependable operation.
Chamberlain’s installation guidance places the keypad within sight of the door, away from moving parts, and at least five feet above the floor or adjacent walking surface, beyond young children’s reach. Follow the instructions for your exact keypad, including appropriate fasteners for the mounting surface. Do not overtighten screws into a plastic housing.
Choose a PIN that is not an obvious address or repeated digit. Keep the instructions and model number somewhere accessible inside the house. After a move, review the opener’s instructions for clearing old access credentials and re-enrolling the remotes and keypads you want to keep. Erasing receiver memory can remove more devices than the outdoor keypad alone.
Troubleshoot without bypassing safety features
If the keypad becomes unreliable, begin with the specified replacement batteries, correct polarity, and clean, undamaged battery contacts. A lighted keypad is not conclusive proof that the batteries are healthy enough for normal operation. Retail specification tables sometimes contain inconsistent battery details, so use the device’s battery compartment and manual.
Next, compare behavior with the wall control and another known-working remote. If other controls work, review keypad programming, lock settings, and compatibility. If every control fails, the cause may be elsewhere in the opener system. Avoid repeatedly changing settings without recording what you changed.
A door that reverses unexpectedly or will not close needs its own inspection. Never bypass a photoelectric sensor to make a keypad appear to work. The CPSC recommends regular inspection and reversal testing. Follow the opener manufacturer’s test procedure, and stop using a system that fails until it has been corrected. Keep people clear and watch the door through its full travel.
Bottom line: choose the Chamberlain G940EV-P2 for a confirmed compatible Chamberlain-family system or the Genie GK-R for a confirmed Genie Intellicode system. Compatibility, readable controls, sensible guest access, and safe mounting matter more than a long list of advertised features.
