Description

LiftMaster 878Max wireless keypad garage door opener is a versatile and secure keyless entry system that provides convenient access to your garage without using a remote control or key. It allows the user access to a home or garage with a 4-number PIN.

This temporary PIN feature only works on the garage door openers with the built-in radio receiver that supports this feature and will not work with external radio receivers. This keyless entry system is easy to use and can be installed in minutes. No additional wiring is needed as the keypad has a completely wireless design. The Security+ 2.0 rolling code technology assures a new code is sent every time the keypad is used and virtually eliminates the interference of radio signals. The backlit keypad makes it easy to see the number, no matter what time it is. It comes with a convenient feature that is a one-button-to-close feature for garage door opener with a built-in radio receiver manufactured since 2006.

  • Got The Job Done
Works great on my Liftmaster garage door opener and was as easy to install as it gets.

  • Best ever 30second setup
Getting this keyless opener was amazing. I read the instructions. Went to garage as soon as I got it. Pushed the lean button on the opener. Entered the 4 # pin. Held enter. Garage door opener light 💡 flashed. Let go. Entered pin, Pressed enter and the door worked perfectly! Took about 30 seconds ! Well worth the extra money! Should have bought this the first time. I wasted my money on the cheap one. It never worked. Would not program. You get what you pay for. The lift master is the best! If you want to be sure it works, spend the extra money, you won't be sorry! ... show more

  • Simple installation. More expensive than universal openers.
Originally had installation issues with Genie (universal opener @ 1/2 the price) and my LiftMaster garage door. Installation of the 878Max was simple. Worked immediately on both doors. No operating issues after several months of use. Best features: One-click button to close garage door and cover to protect keypad. ... show more

  • Easy Set Up
Although a little pricy, it was so much easier to install and program. After fastening it to the outside of my garage, I pressed the learn button on the main unit, entered my pin in the keypad, hit enter and the door worked perfectly. We’d bought another generic brand from a home improvement store years earlier, but always had to enter the pin, plus zero, then “enter” to open the garage door. Because it’s made by Liftmaster, the directions for setting it up were easy to follow. I’m glad I went with a genuine replacement part rather than a cheaper off-brand model. Highly recommend. ... show more

  • You Get What You Pay For
I tried to get around paying the price for the OEM control and things didn’t go very well for me. I purchase two aftermarket, Chinese remotes that claimed they’d work with the smart Liftmaster. After spending close to two hours attempting to program them I returned both. I was frustrated and annoyed but I bit the bullet and purchased this OEM Liftmaster. What a difference! I pressed the yellow learn button on the backside of the motor, entered my four digit code, pressed the enter button and viola! It WORKED straight away. No muss, no fuss, just perfection! ... show more

  • LiftMaster keypad
I received my keypad within one day it was easily installed and easily programmed. However, it included an outdated 9 Volt battery already installed within the controller. This was not a generic $15. It was a genuine LiftMaster for $52! I would expect a new battery with the expected quality of a name brand. ... show more

  • Garage door, keyboard
Replaced our garage door keyboard, and it works great

  • Good!
Had to replace a 878-original after many years of great service - in direct sunlight/heat/humid environment - still worked, but the battery-wire had started to rust - it was time to replace. I have the "yellow learning" button on my main unit - so installation was easy: yellow-code-enter and done! Set-up with other color buttons is a couple extra steps - but still easy (instructions are good - or watch on-line videos). Screw holes matched the unit I had to replace PERFECTY. Code-to-open and 1-button-close work perfectly. This OEM is about 15bucks more than the no-name knock-offs you can get - but I think the few bucks more is well worth it for years of use. If you need it - buy this. ... show more
