I have been seeing some strange behaviour of Homelink on my newly acquired Roadster (2.5). Can anyone tell me whether the car can support rolling code fobs or just static?
I have a Liftmaster 3800 that I believe uses rolling codes. Homelink in every car I've owned has been flaky with it. Most of the time a quick press of the button will open the door, and then others I'll have to hold the button for 10sec or so before the opener does its thing.
Homelink supports both fixed and rolling codes, depending on what your garage door wants. When you are "training" it, using the existing opener lets it learn a fixed code. If it can't learn a fixed code, instead you press the training button on the door controller, and it instead learns the car's rolling code. It requires a few consecutive transmissions to do that. Then in future, if the car transmits a code from "the future", it will again require a few consecutive codes to resync. If you press the homelink button while still out of range, you might cause this behavior yourself.
I was surprised my 10 year old Blue Max opener did not sync with the car... it has a fixed code. However, my newer LiftMaster with a rolling code synced up in 10 seconds with the training mode button depressed.
I bought this universal receiver from Homelink (PR433-4), thinking I could program the car with that. But it looks like both the car and the receiver want to "learn" the transmitter code. :cursing: I'm willing to buy a standard Homelink remote if needed, but I'm sure that one also wants to learn a code first. What device initially creates the code? Can someone solve this chicken or egg dilemma for me?
I just got a new liftmaster myself and to work with the roadster it requires the home link repeater. It plugs into an outlet and Yukon use the home link remote to program the roadster. Works perfect after that was installed too.
