Pros: Sturdy, made from the same company as Garage door opener, Lit keypad, Easy to install, comes with 9V battery and screws

Cons: The battery compartment lid is not easy to open, only 4 digit code can be used

IMPORTANT: Make sure that the button on the garage door opener is RED, otherwise you need another keypad model. check this link [...]

When syncing the code with opener, remember to sync this keypad, car remotes and garage door opener button simultaneously. This means that
1-Press RED button on motor,green LED is lit
2-Enter 4 digit code on remote (as desired)
3-Now press enter key + car remote key + garage door opener button(fixed on wall ,not the RED button) at the same time (may require two persons) , ligth will blink and now all the devices will be synced. If you miss any remote during this process ,it will not work.Of course you can repeat the process.
4-Check all remotes and keypad are working
5-Now install it on the wall, for one of the screws you have to open the battery lid.

I don't know about the long term reliability of the product because it has only been a week since i have installed it.

First: this product is intended for Security+ garage door openers made before 2005. If you have a Security+ opener with a grey antenna wire and/or an red/orange "learn" button on the back, you should be all set. Hopefully, that helps out anyone deciding which model they need.

My opener was made in '97 and has the orange button, and it took me longer to read the instructions than it took to actually program this to work with my opener. You hit the button, enter the code you want, and hold down the Enter button for a few seconds. That's it.

Mounting it was a breeze. You put a screw in where you want to hang the keypad, slide the keypad on the screw, and then put in a second screw where the battery goes (just under the pad) to keep it secure. They even included the 9V battery!

Seriously. If you have a drill, the whole setup and installation takes maybe five minutes.

I was also really happy to save nearly a third of what the local home improvement chains wanted for a flimsy "universal" keypad by buying from Amazon.

The Keypad is a must. It is very easy to use and install. Setting a temporary code is very useful when you grant someone access to your garage.

Just what you need if you have a Chamberlain door that is a few years old. Much better than the universal ones they sell at the big box stores! I use it to control two different openers, something the universal ones won't do.

Replaced an identical model, except it's not. This one drains batteries at umpteen times the rate of the old one; the keys stick so the code doesn't go through, the enter pad has to be pushed very hard at least 2 or 3 times to activate. Not a patch on the old one which was assembled in Mexico. One guess as to where the replacement is made. Short of replacing the whole unit, don't know of any alternative unfortunately.

I have a new Chamberlain garage door opener. No where in the description online does it say that this model is for OLD Chamberlain openers ONLY. Waste of time.

Revision to older review - I liked this a lot when I got it, but it died after about a year.
Just got a newer model to replace it - Liftmaster 976LM/977LM 390Mhz Wireless Keyless Entry Pad - it's quite a bit nicer than this one and costs the same amount. I would recommend buying that over this.

Ordered this keypad to replace an older Craftsman keypad in the same style. WOW - what an improvement. The old keypad often required the code to be entered multiple times, and you had to press the enter button 2-3 times to get the door to open. This one is instant. Couldn't be happier. Changed over in less than 5 minutes. Works for Red/Orange learn button.
