Programming a Marantec M3-631 Keyless Entry

Marantec M3-631 Keyless Entry

Perhaps you just moved into a new home and you don't know what the pin number is for your Marantec M3-631 Keyless Entry. Even if you did know it....you should change it because the old homeowner also knows it (and who knows how many other people).

You are going to need a couple of things before programming the new number into your keyless entry....

1. Programming Instructions: we got you covered here. Just scroll down the page and you see the complete programming instructions. It's probably best to print the instructions out & put a copy in your "manuals" drawer (we know you have one....every house has a drawer where all the manuals from the clock radio to the blender get stored).
2. A Working Remote: you'll need to have a M3-2312 Remote that is already programmed into the operator so you can transfer the code to keyless entry.
3. A Programming Jumper: the program jumper is connected to the M3-2312 Remote and M3-631 Keyless Entry. The code is then transferred from the remote to the keyless. All new remotes and keyless entries come with a program jumper but if you're like most people you'll probably never find it. You can always buy a new program jumper.
   

And a little tip: after you are done programming the keyless take the program jumper & tape it to the back of the keyless....this way you'll know where to look for it if you ever need it again.
