Keychain Garage Door Opener Remote, for Chamberlain, LiftMaster, Craftsman 371LM 373LM 971LM 973LM and More, 2 Pack

This transmitter is tiny. About the size and half the thickness of a 9V battery. Fortunately, it worked perfectly with my driveway gate and garage door. NOTE: This only works with 315Mhz systems. My driveway gate has both a Linear/Multicode (300Mhz) and a Liftmaster (315Mhz) receiver attached. It only worked with the Liftmaster setting. As for the unit itself, it was programmed on the first try. Some observations: - The A/B buttons are good size with a solid "click" sound and feel - There is a small red LED light to also show it working. And to show when to replace battery. - The small cover slides easy and clicks into the open and close positions. No worries of it sliding around. - Three small screws in back make it easy for battery replacement. Did not check what the size was for it. - The C/D buttons are small. If you have large hands, you'll likely use your nail to press it accurately. - Keyhole makes it easy to put on your key chain Overall, great price for two of these, making them worth the purchase.

Works great and is super convenient.

Love these and wish I would have purchased sooner. Definitely small enough to put in your pocket. Set up was easy. Works great.

I recommend these remotes especially if you don't have a car with a built-in remote

I purchased this product to attach to my keychains for each of my streetbikes. It was simple to program and has worked well with my Liftmaster unit. I have only programmed a single button on each remote as I only have 1 door. Although the sliding cover can be difficult to slide at times, I like that it keeps the buttons covered from debris or being accidentally pressed. The only downside so far is the slot for the keyring attachment is narrow, which prohibits movement of the keyring and can make my keychain awkward to fold into my pocket. I just ream it out a little when I get a new one and that corrects the issue.

Nice little remotes, as their actually smaller than I realized they'd be but I really like the compact size after using them for a few days. The locking button cover is the main feature I bought these for as unwanted button presses always happens and I don't want someone leaving the garage door open inadvertently with a in pocket button press. Small con: the cover's lock is less strong in the up position than the down, where there's a more a solid feel to the lock, but it doesn't feel loose at all. The cover's latch is all plastic inside. The remotes CR2032 battery is accessible by removing the 3 little screws from the back cover. The battery they come with doesn't have a name I recognize, but their cheap to replace. I Included a tear down pic for anyone who's curious to see the insides.

They are small so they fit on my keychain. It took a minute to connect both of them.Easy to use & have a slide cover for the buttons so you open or shut by mistake. I have a LiftMaster Garage Door Opener that paired easily.

Small enough to fit on a keychain.

De las 2 piezas que me llegaron sólo una de ellas funcionó y con todo que vino un técnico a programarlas
