Quick and easy!

Bought several of these online from another store . One of them never worked but didn't want to go thru hassle of returning by mail. Searched for another store and realized Walmart online had it all along. Ordered two; got them within 5 days. So much easier and I felt good that returns could be made locally, if necessary!!


It worked for a little while.

I programmed it and it worked a couple of times, then stopped working. I programmed it again, and got the same result. Now have to get with the original company, return it to them, and pay a "restocking fee" for the pleasure.



Works great. Just what I needed


Liftmaster Keychain Garage Door Opener

Did not work with my liftmaster garage door receiver


Waste of Money

I did bought this for my garage door but when I got this and when try to program it on my garage door the product doesn't work then I called the shipper to tell them that I need to return this to them because it doesn't work and maybe they can send me a similar one that can work on my garage door, they told me that I need to pay for return shipping and need to wait for them to receive it and refunded to my account then I can choose what replacement I want.
