Programinf Older Garage door ?
We just purchased a 2009 CG Coupe and trued in vain to program, garage door. Dealer came out and spent m4 hours with engine idling with no success They indicated that they have never had this much trouble before. I searched online and tried all tips with no results. What pissed me off was all other cars(non-GM) owned use Homelink which works perfectly. Apparently GM chose to cut costs and use Lear Home 2U system I think it is not computable with my od Challenger Garage Door Opener. Yes the openers are over 25 years old but still functions perfectly. So I I guess I ether use the remote openers or replace both garage door openers at a considerable expense?

You mentioned the "dealer" came out and spent "m4 hours". If you meant 4 hours, that is hard to believe. That would be like spending 4 hours trying to put a nut onto a bolt before you realize one is metric, other is SAE.
What "dealer" was it? GM...Challenger...Lear? It would seem the only people who can help you are the Lear people, since they designed the interface. Unless there is someone on here who has fixed the same problem you are having, I would contact Lear.
Shall we assume you have been using the original remotes up to now? I hope you can get it figured out, but if not, you still have a great car, and remotes to open the door.

attempting to program the unit.!!! I agree is was stupid! But they didin't want to admit that their junk Leart2U would not work on my opener. Just purchased the car from the dealer and they assured me it would work.

Here's a document with detailed instructions from Lear...also there is an 800 number to call where they will help...

I had problems programming the homelink when I got the 08.Then I accidentally erased all the remotes. After that I was able to program it no problem. It seems that my garage door has a max on the number of remotes that can be programed to it...yours may be the same.

You can buy a new garage door receiver and remotes for your existing openers. No need to replace your openers themselves.

Well, mine's a Craftsman from '92-'93 and it was a bear for my '08. I actually followed the old instructions about standing up there near the opener mechanism, holding some buttons down, etc. When that didn't work, I just tried the method of sitting in the car and doing it. It was so long ago that I don't remember what exactly I did, but I think it was the more modern method. Short of that, I'd use the plastic garage door openers rather than change out the motor.

My 2011 has the Lear system. When I bought the car over two years ago I was able to program it to my older garage opener without a problem. Then I put a new door and opener in and the fun began. I followed the procedure dozens of times and gave up. A few months ago I decided to try again....no luck. I finally called the opener mfg and was told that GM inadvertently left their codes out of the programming so I am SOL. Nothing can be done to make it work.

I did exactly that some years ago on a 30 year old sears door opener, to get the rolling codes. It worked very well for another 5 yrs then the motor went out.

No need to cheapshot GM. The issue is between the garage door opener companies and Homelink / Car2U. I just installed a new Chamberlain garage door opener. I was able to program my 2015 Dart w/ Homelink. My wife's 2012 Elantra and daughter's 2013 Accent both have Homelink and were incompatible with a 2016 opener. I had to buy a Homelink "repeater" in order to program them. My 2013 Corvette would not program so I had to buy a Car2U "repeater." Current openers have technology which is not backward compatible. I would say that you got your money's worth out of your 25 year-old opener and it is not reasonable to expect it to be compatible with transmitters made 20 years later.

I've an '08, connecting to an ancient opener was challenging, but it can be done.
IIRC the procedure's time sensitive, if requested info isn't entered within a few seconds it craps out. Have to start, again. Meant I had to thoroughly know what codes to enter, when. No pause to think.
Follow instructions to a T being mindful of time taken to enter data.

And the reverse is also true....an opener manufacturer comes up with a new standard in 2014...there's no reason to expect a universal transmitter made in 2005 to work with it. I agree that this is not a GM issue. GM is not an electronics company...they buy the transmitters from Homelink and Lear and must hope for the best. GM doesn't include or exclude codes...GM buys a transmitter from one of the two companies that make them, just like every other car maker does. I still believe that a significant percentage of these problems are errors in programming by the users...not all, but many.

I had never heard of Challenger Garage Door Openers so I looked them up. It looks like they are the old type of garage door openers that use what is called Fixed Code protocol for the opener, basically 8 to 12 dip switches. Homelink Remotes in a car can hook up to that type basically the same way they can to the newer Rolling Code protocol openers, however Lear Car2U remotes require a special procedure that is outlined in the Corvette owners manual. When I bought my 2013 Corvette, I had old Craftsman openers that used the Fixed Code protocol and I successfully programmed the in car remote. I have since replaced the openers with new Liftmaster and the in car remote in the 2013 doesn't work correctly with the new openers but that is a different story in a different thread on the forum.
In the 2013 Manual, the "How to program" Fixed Code openers is on page 5-62. Look thru your manual for Universal Openers - How to Program and see the part about Fixed Code Openers. You can also check to see if your opener is Fixed Code by looking at the back panel on the opener and seeing if there are a bunch of dip switches on it.
It took me about 3 tries to get the 2013 Corvette to work with old Fixed Code opener, so patience is highly recommended.
