LiftMaster Garage Door Opener Confirmation


I’ve managed to finally understand the steps needed to read an RF device and emulate.

I copied my garage door opener LiftMaster 87504-267. After several successful activations, I think I can call it a confirmed success. Surely my accomplishment is not significant compared to what others have accomplished. Just leaving the note in case someone is aggregating successful attempts and model numbers.

Would love to read how you were able to do it. I’m trying to do the same thing for my garage opener but it is a craftsman 1/2 hp garage door opener 41a4315-7d. Out of my research, it seems to use security + 2.0 on 390 Mhz but I was not able to succeed in reading the signal


I just got it to work after two days of trying. I used the frequency analyzer to see that my Liftmaster transmitters output on 310 and 390. the flipper prevents me from tx on the 390 band here in the US. So I gave it a shot adding manually the Liftmaster 2.0 310mhz. I saw on a couple videos that to pair some universal remotes you need to keep pressing the send button multiple times about a second apart, I believe its because the RX needs to lean the rolling code algorithm. After about 8 presses on the FZ and with the opener in learn mode the door finally opened. However it will sometimes take a few presses on the FZ to get the door to open. I suspect this is because the codes don’t sync up perfectly. It does always work though within 3 to 5 presses. Tip: when the opener is in learn mode space the presses about 1 second apart, you do not want to press it again after the opener notifies you the TX is learned. Otherwise I think you’ll unsync the codes. Not sure if it will work for everyone, but this is what worked for me.

Sorry, totally new, trying to copy my gate remote, anaylzer says 390, I manually added the Liftmaster 390 and clicked READ, while pressing gate remote. Doesn’t read anything. Am I missing something? Should I read RAW? Thanks!
