Tools and Hardware Reviews of Liftmaster 66LM Billion Wireless Keyless Entry - 390MHzCustomer Review: Keyle Doorr Entry a Good Purchase Summary: 5 Stars
Product: Liftmaster Wireless Keyless Entry Pad 66lm
Price, ordering, delivery, arrival condition all excellent as usual.
I purchased this as a replacement for one which had failed. Installation was easy if you can read less than perfect instructions. I am handy with electronics, so it was a breeze.
Product works by keying in a 4 digit code after which your garage door opens. The human interface is good and easily used by anyone who you give the code to.
I also use a wileless opener which operates from my car. There were some problems getting both devices to work together as initializing either divice would render the other inoperable. I recall that the problem was resolved by setting the dip switches in the garage door opener and the car remote and "forcing" the kepad entry to be compatible. It took about 15 minutes to figure this out and it was about a year ago, so I do not remember the exact solution.
The battery lasts about a year, the product looks high end, is easy to operate. I wish it had a 5 digit securty code or a lockout for 10 minutes after 4 attemps, etc, to make the product more secure. For best protection, I recommend that before you go out of town that you disconnect the garage door opener drive unit and lock your garage door.

If the back of your opener has dipswitches, then you need a 65lm wired keypad or a universal keypad that is compatible with your opener. The Liftmaster 66LM will NOT work with Security + Openers.(See either the 976lm or 377lm-If learn button is a redish orange color, then you need the 976lm. Purple-377lm.). The 66lm is the same as the 740CB Keypad.
