From the Manufacturer
The wireless keyless entry pad from Chamberlain allows secure, coded access to your garage without a remote control or keys, just by entering the private 4-digit security code you determine. Just like the rolling code in your remote control, the keyless entry transmits a new code with every use, one of over 100 billion, never to be repeated. Also has the ability to be programmed for a temporary password. This model mounts easily on the garage door jamb without any wiring or hardware required. Illuminated for nighttime use. Only for use with Chamberlain Security+ garage door openers.

Customer Reviews

Does its job
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 http://www.chamberlainremotesonline.com/?gclid=COyJ0Z-auJgCFSIgDQodWF7AbA

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.

Got to have it
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.

Inadequate Information Supplied for Purchase
The product description failed to state that the keypad was intended for garage door openers manufactured prior to a certain date. My garage door opener was new. It was sent back to Amazon for a quick return and credit to my account. Thanks.
