Question: Will the car remotes remain functional once the keypad is programmed?
Document: To back up a review by Cincy, I was able to program the Liftmaster remote to my Sears opener (139.536XX) only after I reset all codes on the opener, but then my existing Sears car remotes (139.53681B) did not work. I then programmed my car remotes back but then the Liftmaster remote wouldn't work.
I have a Craftsman 139.536xxx garage door opener. Attempting to replace a 139.53684 SECURITY+ keyless entry pad, I purchased the 977LM Liftmaster+. I was able to program the 977LM, but all my other remotes were rendered useless during the new keypad programming process. There was no way to program the new keypad AND my car remote or OEM transmitter.
Easy installation and instructions to program. I have this one keypad programmed with two different codes to operate two single car garage doors. I was unsure if this was do-able but am very happy that it works.
For years I used the Craftsman keypad that's equivalent to this. It was fine and a huge improvement over not having anything. But this LiftMaster one is much better and here's why. First it's much cheaper. This may sound obvious, but I was shocked to look into buying extra remotes for the Craftsman system and to find they were so expensive. Liftmaster seems to be much less in general and that just gives you more options. The big functional improvement for me is when you type a bad code.
I am very happy with this item. Very easy to install and set-up and works seamlessly with no conflict with my other remotes and integrated car remotes. Now,  I can go for walks in the neighborhood and leave my bulky car remote and keys at home and come back in through the garage. Easy, simple, useful.
Bought the product and followed the directions. Everyone has a different color learn button on the garage motor itself. Mine was red. No big deal.I purchased the keyless 976LM Entry pad along with an additional remote for my car( for guest) when I programed the new keyless entry pad along with the new remote my other existing remotes do not work in my car and mine. Why is that?
I have had no problems with my car remote working after I programmed it as reported by another buyer. My old keyless remote had stopped working after 11.5 years no matter how hard we pushed the buttons. Quick delivery and happy to have a working Keyless entry again! !
I bought two three button remotes and this keypad for a ten year old door opener. All three items were in what looked like original packaging and were easy to set up and use. All currently work great.
This was very easy to install and program. I was able to install and program the keypad in a matter of minutes. The single keypad operates 2 doors - the key code must be different for each door. Programming of the keypad did not affect any other existing remotes.
Works better than my darn car controller. Easy to mount and program. Keypad light is plenty bright and battery life is good considering Its always outside in the cold and wet
Answer: yes
