If you are looking for specific instructions to program a Chamberlain, Craftsman, or Liftmaster remote or programming a Genie or Overhead CodeDodger remote we have specific instructions on how to do them by clicking on the links. We also have separate pages for the Liftmaster Keyless and Genie Keyless entries.
To program your car or vehicle garage door transmitters you should use the programming directions supplied by Homelink which is part of Johnson Controls.
The days of setting code switches on your garage door opener transmitter to match the switches on the garage door opener receiver has went by the wayside 15-20 years ago. Once the FCC limited the number of frequencies the manufacturers could use there were simply too many that were being set to the same code which caused security problems.
Once all of the transmitters from the same company were set to the same frequency there were simply too many instances of neighbors and strangers being able to open a number of different doors in their community. First many people simply left them at the factory default setting since they worked out of the box even though some set every opener they made to the same code. The other problem was that many people that did change the code simply set the codes by switching every other dip switch. Therefore even though they did change the code they were changing it to be the same as many other people. We even use to occasionally run test in neighborhoods by driving down the street to see how many doors we could open. Sometimes the numbers were actually surprising.
Therefore the solution to resolving the issue was to give each transmitters it’s own unique unchangeable code at the factory and to never duplicate the same code twice. That means that there are literally over a billion different code possibilities. Once the garage door transmitters no longer had switches to set to match the opener, the openers needed a way to “learn” the factory preset code from each individual remote instead.
By pressing & holding the learn & smart button it will erase all of the memory in case you should lose one of the transmitters or forget to remove them from a vehicle before selling or trading in it. Once the memory is erased you simply use the learn button again to code all of your existing remotes back into the unit.
