    Possible to program garage opener with rolling code for two cars?

    I have a new house with two Chamberlain LiftMaster garagedoor openers. Now I would like to enable the "HomeLink" keys in my wifes and in my car to open both set doors individually.

    Is it possible to have the Liftmaster "learn" to recognize both cars? Or am I limited to one car per opener?

    Does each door have a separate opener. If so you should be able to learn each remote into the buttons in your car just fine.

      Yes, I have two separate openers and remotes. One for each door.

      What I was curious about is; Can you have multiple cars trained into the rolling code sequence of one opener? Or does pressing the "learn" button on the opener (in the ceiling) erase/invalidate any previously trained cars...?

      I need to be able to open any door with both cars.

        Rikard,

        As long as the built-in "remote" in each car is rolling-code capable and has multiple buttons, you should be able to have each car learn each of your two remotes (each remote on a separate button of course.) Then each car can open either garage door. I use Genie garage door openers with rolling codes and was able to do what you are asking. The motor units should learn many individual remotes and not erase a previously programmed unit when learning a new one. Check the Chamberlain manually carefully - there should be a procedure for adding more remotes and also one for removing remotes.

        Try this programming procedure (assuming 2 door openers and 2 cars):

        1) Teach the "remote" built into your car the code sequence of the hand-held remote for the door #1 opener. Follow your vehicle mfgr's instructions for this.
        2) Teach the door #1 motor unit this "new" remote in your car. Carefully follow the instructions provided by Chamberlain.
        3) Teach the 'remote' built into your car the code sequence of the hand-held remote for the door #2 opener.
        4) Teach the door #2 motor unit this "new" remote in your car.

        Repeat this same sequence on your wife's car.

        Hope this helps.

          Most of the openers today have receivers that can respond to multiple remotes - you just train them according to the instructions with the opener/receiver. For example, the Genie Intellicode receiver ($50) I retrofitted to my garage door opener can use up to 7 remotes or wireless keypads. BTW, the Genie is a nice remote system for those of us looking for secure RF remote use for HA, not a bad price, either.

          If you use the same single remote in one car on both doors, hitting the button will open both garage doors at once. If you use two separate buttons or remotes in the same car, then you can choose which door to open.

          I went with the Genie because I also have a door lock that has a garage door button using the Intellicode signaling, and so one fob can be used for garage, door, and lights. Cuts down on the keychain items.

            I have an older garage door opener that I upgraded with the rolling code controller. Both my car, my wife's car, my sons keyfob, and our wireless numeric pad access all work together. You just put it in learn mode anytime you get a new device, have it learn it, and it adds it to its list without removing the old ones. Works great, and very high WAF for the integrated in the visor garage door opener. She doesnt have to change batteries, and most importantly cant lose the thing.

              off topic a bit, but I want a new opener which is high tech as you all discuss, but also the most quiet I can find. Is this a belt drive? Chain? I think screw drive is the worst.

              Quiet Brands?

                supposedly the screw drives are the quietest, so I bought one, and I have to agree with you, it is very loud! I would check out epinions.com.

                  We have two screw drive Genie Excelerator with DC motors. They are very, very quiet compared to any of the AC motor based openers we've had in the past. We've been quite happy with the low sound for the past three years. Here's a link to the product: http://www.geniecompany.com/Products/excelerator.htm

                    We have chain drive openers and they are loud but for now I prefer that as I have a 17 year old daughter who has "borrowed" Mom's car a time or two - without checking with Mom - lol. Makes for an effective deterent / garage door announcer.

                      <BLOCKQUOTE class="ip-ubbcode-quote"><font size="-1">quote:</font><HR>• Genie Excelerator ISD900-2 (*est. $200)

                      &gt;&gt; Genie's Excelerator represents the state of the art in screw-drive garage-door openers: It closes the door at the standard rate of seven inches per second, but opens it twice as fast, and reviewers say the ability to get into the house quickly offers an extra security advantage and convenience. Plus, this Genie starts and stops gently to decease wear. The Excelerator has a safety sensor that automatically reverses the door if an obstruction is detected, plus a vacation lock. Experts recommend this model more than any other garage door opener on the market.
                      • Craftsman 53964 (*est. $220)

                      &gt;&gt; If quiet operation is your top priority, experts say belt-driven models are the most quiet. This Craftsman model beats the Genie Excelerator in noise tests, but experts say it isn't quite as easy to install. This 1/2-horsepower model has rolling code technology for increased security, and has a safety reverse feature, but the Craftsman 53964 opens the door in about twice the time as the Genie above.

                          I have to agree w/ Dan (xplosiv) on the Genie Excelerator - it is the quietest door opener I've ever used. It also has accel/decel at the ends of travel and has a 2x open speed if you have sectional doors.

                              Just to emphasize, the Excelerator screw drive is QUIET, not loud. I've had the belt jobs in the past, and they were much louder. But, I think much of this has to do with the Excelerator using a DC motor. If you live in the DC area, c'mon over for a listen!
