Our ancestors would marvel at our big conveniences (what would St. Augustin have said if someone had shown him a car?) but they might laugh at our little conveniences. A garage door opener, for instance.
So what. They should get with the times or stay where they are. The reactions of the ancients don't matter much. But what does matter is when last generation's technology still works but is no longer supported. That is just waste, and it bugs me.
So in this house that we recently acquired is a first class, smoothly operating, ultra-reliable Canadian-made Steel-Craft garage door opener. Two, actually, dating back to about 1983, but only one remote control. And a garage door opener without a remote is actually an anti-convenience, because you have to go around and inside the house to open the door that you could have opened, if it was strictly manual, by standing in front of it.
Steel-Craft uses components from LiftMaster, one of the big two surviving giants in the business. (The other is Genie, which I have no recent experience with). LiftMaster has been in business for over 100 years, and have had to keep up with the times. A LiftMaster garage door opener from the late 1970s relied on a remote control that had 9 little switches in it. As long as you set your 9 switches in different positions from anyone else in the neighborhood, your opener would not open anyone else's, and theirs would not open yours.
Then some perpetrator figured out that with a 315Mhz scanner, he could lurk around neighborhoods and either steal codes as people used them, or work through the fairly small number of combinations of switch settings. And when the owner of a house with an attached garage was away, the perp would open the garage, enter it and get into the house through the most vulnerable entrance.
Modern remotes use a rolling code system that makes it almost impossible to steal codes. And they don't have any way of activating that quaint 9 switch system. If you have a pre-1984 garage door remote from LiftMaster, Sears Craftsman, True Value, True Guard, Garage Master, Master Mechanic, Home Hardware (Canada), Steel Craft, Access Master, Do-Its, Anaheim Door, or Garage Door of Indianapolis, chances are that remote was manufactured by a company called Chamberlain and it is near the end of its commercial life. These are not supported any more and their replacements are getting harder to find.My one original remote is a Chamberlain 51LC. I need another one for the other door. Know what? You can search the internet all day for replacement remotes and not find a reference to a 51LC. Unless, of course, you check in with Halfwise, who is here to tell you that a LiftMaster 361LM will replace a 51LC. So will a 362LM, and it comes with two buttons and two sets of 9 coding switches, one for each door. Got 3 doors? Get a 363LM.
