1 for Marantec Harrison Martin M3-2312 315 MHz 2-Button Garage Door Opener Remote Replacement Program Pin, Compatible with Marantec Garage Door Keypad

Very inexpensive compared to what you’d get from a garage door company. Extremely easy to program and has worked reliably. Had no issues whatsoever with my existing system so the compatibility is there. Durable as well.

These work as a perfect replacement to my old garage door remotes. Easy to program. Just a tip, once you program one, use the little 3 prong thingy to program the other remote by sticking them together and pressing the button on the programed one. It took a minute to figure out how to do it, but it was very simple.

I bought this to replace my failing Marantec opener because I didn't want to pay fifty bucks for the original. I'm so glad I went this route. It was super simple to install and program. The buttons light up bright and it works great, every time! Save some money and go with this one; works great and I highly recommend it!

This is the kind of amazon experience you hope for. This gimmick was affordable, arrived next day, and perfectly met my need. I'm old and wear glasses, so I had to take a picture of the instructions written in 4pt. font, but they were clear and easy to follow once I read them. They also offer a QR code which brought me to YouTube video for the instructions. Those confirmed what I'd read in the instructions, and I personally prefer to see it done in a video. This remote even came with a weird little proprietary connector to clone the existing controller to your new one. It's a poor design on the part of the manufacturer that this is the way you have to do it, but it was a lifesaving tool from this vendor that they included said tool. Reading the instructions, watching the video I was up and running in like 5 minutes, including unboxing. I'd give this thing six stars if I could!

Was very easy to set up and install. I do not like the pull up cover (just my perference). Works fine. Just installed so I am not sure how it will work in the AZ summers.

It took about 30 seconds to program; quality is as good as any opener I've had; came with the battery; good range; great price; comes with the clip for visor. Recommended.

Garage door opener work absolutely perfe t. Very easy to program...both of them done in about 30 seconds!

Easy setup. Works great.

Très facile à installer et à programmer. Pour une fois que les instructions sont claires et fonctionnelles.

Simple à programmer et fonctionne parfaitement!

Funcionó excelente a la primera. Las instrucciones escuetas, lo utilicé para un Motor Amarr antiguo

I was worried because this was replacing an older discontinued garage door remote. But programming it was a piece of cake, and it works fabulously.

Great opener easy to to program I took three seconds
