2 for Chamberlain LiftMaster Craftsman Garage Door Opener Remote Replacement 893LM 893Max 891LM 371LM 971LM 973LM

They work with old and new openers and are easy to program. You can actually program on old opener on one button and a new opener on the other button

Easy to program and easy to use. Very small too. The only downside to a garage door opener on your keychain is that you may, on occasion, inadvertently open the garage door.

Very easy to program and worked perfectly . Nice compact remote that is perfect for my car keychain.

I got one of these for my motorcycle key ring. I wanted something small and these really are. They don't have the long range as a big visor mounted door opener but they are so convenient and small, they stay on your key ring out of the way. The directions for shifting modes to program your door opener weren't the greatest but understood. Once I held both buttons to switch modes, programmed easily.

My garage door had been opening and closing by itself for 12-24 hrs, maybe longer? I knew immediately when the outside pad was jammed that it was these new Chinese fobs. You get what you pay for. Thank God the motor didn’t overheat, catch fire and burned down, or burn itself out. To save $60 to buy two MasterCraft fobs. I could have cost myself so much more. The motor was so hot, I could smell it. My dogs, bless them, could hear something wrong. Of course I couldn’t see anything so kept scolding them for barking! Next time, I will look!! As you can see, I took the fobs apart, still they were jamming their signal? I had to climb up, unplug the motor to stop it from overheating and stop the door. Then I could pry the battery out of its three sided cage attached to the motherboard. I had to use an anvil to loosen the cage. These are very dangerous. I read the glowing reports. I have no idea what caused mine to go demonic? Nothing was touching them, or pressing them. One was exactly where I put it 5 days ago upon arrival, programming and testing. It just sat in the key tray. The other was also programmed, tested and used about six times, the last on Friday. Everything was fine Saturday morning. Sunday morning the wind (60 mph) started, and continued Monday. Monday late morning I saw the door up, down, up, down… The wind just kept us indoors. Nothing to do with the signal. My car fob and demonic fob hung from my purse? They just went bananas?? Thankfully thru all this, I found the original MasterCraft visor opener. So happy to clip her back on. I’ve already printed the return label. I’m sorry they aren’t getting back what then sent. But small price to pay given what would have happened if I didn’t catch on. Absolutely do not buy these for anyone disabled or geriatric who won’t be able to navigate these fobs going haywire. Never again! I don’t care how many great reviews there are!

These openers have worked great, but I marked them down because they did not have any instructions. I was going to return them but, I clicked on another seller that included some instruction in their description and that got me through. No instructions on the description or in the box is a definite negative.

These things are AWESOME. Very small, so not bulky on a keychain, great for my h.s. kids that park outside and i don't want them leaving a garage door opener in their car. set each one up in under 10 seconds. push the button on garage door motor, hold the remote button until light flashes on garage motor, boom, done. 10/10

Worked great at first. Now I have to press the button a million times to get it to open. Not sure if I need to repair it to the garage door opener or what but it’s kind of annoying. This is only happening with one of these remotes btw.
