UPDATE 03/01/14: The M3-631 Keyless Entry has been discontinued. It has been replaced with the M13-631 Keyless Entry. You can see the new M13-631 Wireless Keypad here at the Garage Door Zone Store and see how much they've improved the keyless entry. 

Below are the programming instructions for the Marantec M3-631 Wireless Keyless Entry

The New M13-631 Marantec Wireless Keyless Entry

Marantec has recently introduced the new M13-631 Wireless Keyless Entry for their garage door operator lineup.

Marantec M13-631 Keyless

Over the past few years Marantec has been using the M3-631 Keyless Entry for all of their current openers but there were a few drawbacks to that keyless. Fortunately Marantec seems to have addressed some of those issues and made improvements in the new M13-631 Keyless Entry.

This keyless works like the old one in that you pick a 4-digit PIN number to operate the opener. That's where the similarities seem to end. Here is a list of some of the improvements with the new keyless entry:

• Holds 4 Different PINs - you can program it to work four separate Marantec openers or program one opener with four different PINs
• Improved Faceplate Numbers - the numbers are now raised, backlit and harder which means they should last longer from use
• Slide Up Cover - the cover over the numbers slides up instead of flipping up which will keep it from blowing in the wind & breaking like the old one
• Uses AAA Batteries - the unit includes (and uses) two AAA batteries. Easy to replace batteries and should last longer than 3volt batteries
• Low Battery Indicator - now you don't have to guess if the batteries are low. Keypad buttons flash when batteries need replaced.
• No Jumper Needed To Program - the old keyless needed a jumper to transfer the code from the remote to the keyless. Most people lost or misplaced the jumper so it wasn't convenient. With the new M13-613 Keyless you just hold a working remote up to the keyless & press the button on the remote to start the programming process.
• Programming Tip: install a new CR2032 3-volt battery in your remote before you try to program the keyless. With a strong battery the programming should work fine. With an older battery in the remote it may take 7 or 8 tries (or may not work at all). 
• Programming Instructions: you can find the M13-631 Keyless programming instructions here on our Manual Support Site

With a little thought it seems Marantec has improved the design and functionality with the new M13-631 Wireless Keyless Entry. Sleek new design, easy programming and durability. A great addition to go along with the following Marantec opener models: M55, M4500, M4700,  Q7500, Q7700, Q7900, M4500e, M4700e, M4900e, Synergy 270, Synergy 370, Synergy 380

Not sure if your opener is compatible? Look at the remote for your opener. If 315MHz is printed on the back of the remote then the M13-631 Keyless will work with your opener. You can also use the Contact Form on the left side of this page and we'll be happy to help you.

Every week we answer common questions about garage doors and garage door operators that we receive in our mailbag. If you have a question please email us at: Support@GarageDoorZone.com.

Q: I need instructions on how to reprogram my keypad remote. It doesn't remember my password any longer and the change password instructions don't work. Where can I find programming instructions? - Tom  

 A: Great question Tom. We all do it - we buy a new product and throw the instructions in a drawer. Then when you really need them you can't find them. Not to worry though - Garage Door Zone has a Support Site with a lot of different programming instructions and installation manuals (and we're always trying to add more). Visit the Garage Door Zone Support Site and look up the keyless entry, remote or garage door opener you need the instructions for. If you don't see the particular set of instructions you need send us an email (support@GarageDoorZone.com) and we'll try to get it uploaded for you.

4. Congratulations - you have successfully changed the pin code on your M3-631 Marantec keyless entry. The old pin number is now no longer valid.
