Who it fits

Key specs explained for this opener

Model: 877MAX Keypad and 893MAX Remote

This listing includes both a wireless keypad and a handheld remote. You get two ways to access your garage. The keypad allows PIN entry while the remote offers button convenience. This combination suits households needing multiple entry methods without installing new hardware on the door unit itself.

Compatible with Security + 2.0 and 315 MHz

The device works with Liftmaster and Chamberlain openers using yellow or purple learn buttons. It also supports 390 MHz models with red, orange, or green buttons. You must verify your opener has one of these specific button colors. This ensures the new hardware communicates securely with your existing motor system.

Keypad accepts up to 3 PINs

You can program three distinct codes into the keypad. This allows family members or frequent visitors to use unique access codes. It replaces the need for physical remotes for some users. This feature is useful for managing access without tracking down lost plastic remotes or sharing a single code.

Remote range: about 100 feet

The handheld remote works from roughly 100 feet away. This allows you to open the door before reaching the garage entrance. It provides convenience for multi-car families or large driveways. You do not need to be directly next to the door to operate it. This range ensures reliable signal stability.

Dimensions: 6.93 inches by 4.69 inches by 1.34 inches

The keypad has specific physical dimensions for mounting. Its clamshell design protects the buttons from weather. The backlit numbers help you read them in the dark. These size constraints matter if you have limited wall space. The waterproof material extends the service life of the unit in outdoor conditions.

Build, size, and layout details

The listing describes a gray keypad and remote set. The keypad uses a clamshell design. This shape covers the buttons when not in use. The material is waterproof. You can install it in outdoor areas where rain or snow might fall. The backlit numbers help you read the code in the dark. This feature is useful for evening access without needing an external light source.

According to the listing, the keypad measures 6.93 inches in length, 4.69 inches in width, and 1.34 inches in height. These dimensions allow it to mount securely on most exterior walls. The compact size keeps it from being overly obtrusive. The remote is designed for handheld use. It fits easily in a pocket or purse. The gray color matches standard garage hardware finishes.

The keypad is completely wireless. It runs on batteries that are included. You do not need to run power lines or wires for installation. This simplifies placement near the garage door. The layout separates the keypad and remote into two distinct tools. You enter a PIN on the keypad. You press a button on the remote. Both methods provide reliable control. The waterproof build and clamshell cover protect the internal electronics from weather damage. This design choice extends the service life of the device in outdoor conditions.

Setup and everyday use

Setup begins with matching the device to your opener’s security protocol. The 877MAX keypad works with Liftmaster, Chamberlain, and Craftsman openers made since 1993. You must identify the learn button color on your motor unit. A yellow button indicates Security + 2.0. A purple button signals 315 MHz Security +. Red or orange buttons correspond to 390 MHz Security +. Green buttons denote 390 MHz Billion Code. The keypad does not work with Craftsman series 100 models or specific older serial numbers. You program up to three unique PINs to control different openers. The keypad is battery powered and completely wireless. You place it in your desired location without wiring. The 893MAX remote pairs with openers featuring yellow, purple, red, orange, or green learn buttons. It replaces several legacy models like the 891LM and 373LM. Daily use relies on these programmed credentials. You enter a PIN on the backlit keypad to open the door. The backlight ensures readability in low light. The clamshell design protects the buttons from weather. The waterproof material supports outdoor installation. The remote offers a working distance of about 100 feet. This range allows roll-in access without waiting. You can carry the remote for multi-car families. It serves as a replacement for lost or broken units. The device operates on battery power included in the package. You do not need a key or separate remote control for the keypad function. The system provides two distinct methods for garage entry. One uses numeric codes, and the other uses a handheld transmitter. Both methods integrate with your existing security infrastructure. The setup process is straightforward if your opener matches the supported frequencies and learn button types. You verify compatibility before installation to ensure proper function.

Compatibility Checks Before You Buy

Before you add this JUSTHILLUP combo to your smart home, verify your opener’s learn button color. The keypad only works with Security + 2.0, 315 MHz, 390 MHz, or 390 MHz Billion Code systems. It is not compatible with Craftsman Series 100 or specific older models. You must ensure your motor unit matches one of these protocols. The keypad requires batteries, so keep spares on hand. The clamshell design helps protect the buttons from weather, but you should still check the seal periodically. This device fits well alongside video doorbells and smart locks as a secondary access method. It does not replace your primary entry system. Use it for guests or family members who prefer codes over apps. The remote adds convenience for multi-car households. Check the range requirements if your garage is far from the street. This unit is a straightforward solution for basic access needs.

Check before you buy

• Verify your opener’s learn button color matches the supported protocols.
• Confirm your Craftsman model is not in the excluded list.
• Ensure you have spare batteries for the wireless keypad.
• Check if the 100-foot remote range meets your driveway length.
