You need the dealer to reset the computer I think they call it the handover procedure. I just had the same issue and my local Porsche shop fixed it in 5 min.

 

Thanks a bunch. Mine is an 07' so hopefully that will be covered under warranty...

 

Hold 1 & 3 down so it can delete the old codes, then start over.

 

That was not the problem...I held 1/3 several times, but if your "gateway" is not set up from the factory, nothing will happen and you will grow blisters before you get it to work.

The dealership ended up activating the gateway, then it worked like a charm.

CLIFFNOTES: IF YOU ARE TRYING TO ACTIVATE YOUR HOMELINK, AND YOU ARE NOT GETTING ANY BLINKING LIGHTS (EITHER BY TRYING TO CLEAR CODES OR BY PRESSING ANY OF THE 3 BUTTONS), THEN YOUR GATEWAY IS NOT SET UP AND THE DEALERSHIP WILL HAVE TO GET IT SET UP.

 

Your right! Your not losing your mind. The problem is not going to get better with a reset. The control unit in the bumper is broken and needs to be replaced. I just had the same problem. Took it back to the dealer twice. I couldn't get the light to come on at all. Porsche dealer replaced the unit in the bumper. I took it home, programmed it holding 1 and 3, lights blinked and cleared all codes, pushed button three (my choice) till the light started blinking, held the remote by the bumper till the fog lights blinked 3 times, pushed the learn button on the overhead garage door unit, got in the car (quickly) and pushed the button (3) again. Bingo all done. Your homelink control unit in the bumper is broken. Hopefully your still under warranty like mine was at 44k miles. Good luck.

 

I have a 997 and a Liftmaster garage opener. I am pretty sure that my garage opener (model 2000SDR) does NOT have rolling codes. As a result, my thinking was that after the car "learned" the remote's signal, per the first part of the car manual's instructions, I should be done.

That is, I thought that through the learning process described in the car's manual, the car learned the remote's signal and would henceforth replicate it, so that the remote and the car would become identical to the receiver.

Sounds logical, no? Well, it turns out that's not the case.

The car does "learn" something through the process described in the manual but that something does not seem to be identical to whatever the remote is emitting. I am saying this because the car, after the manual-specified training, could NOT open the garage door. In other words, after training, the car was not identical to the remote.

It seems that you still have to get the receiver in the garage to "learn" whatever the car is emitting after the in-manual training. As if you had bought an extra remote from a store that came with "its own" code.

How to do this last part obviously depends on your garage door opener, but the overall process must be rather generic. You push some "learn" button on the garage door opener and then push the button in the car so that the receiver can learn it. That's what I did after completing the first part of the in-manual instructions and it worked like a charm. (I now hope that what I did is not just the second part of the in manual instructions...)

 

Unless your Liftmaster is really old it probably has rolling oode technology especially if you found the learn button. So sounds like you did just what the manual says.

 

You can program multiple types of openers. I programmed my garage, had to follow the second set of instructions. Also programmed my entrance gate, which was a bit tricky, but it holds both codes. Also programmed my parents garage, so three different brands and all works. But as you guys said, it took me a good 30 minutes to get it sorted.

I have noticed that the range is crap, my factory opener will work from almost 1/4 mile away, the Homelink has to be within 50 feet. It's also a pain as I back my car into the garage and find myself having to reposition the car front first to close it sometimes.

 

Just to update this long-quiet thread -- In 2011, LiftMaster changed their coding to something called Security2+ or something like that. This coding is no longer compatible with Homelink, the units used on our cars.

I found this out after trying everything under the sun to get the Homelink system in my 2012 Targa 4S to recognize the remote for the new gate in our community. You should have seen me dancing around in front of the car, remote in hand.

Finally went to the LiftMaster website. They said you can buy a repeater from them for about $50 that will make the unit compatible with Homelink but, since this is for a community gate, the repeater option is out even if I was willing to spend the money.

So -- just an FYI. Anyone know if the Homelink in our cars can have its firmware updated??

 

Speaking of security, make sure you clear out your garage door codes from memory before selling your car. I bought my 997 second hand, and it still had the previous owner's garage codes on the Homelink buttons, not to mention his home address (as well as all the places he went using the Navi). I pretty much saw everywhere he ever drove in the (low mileage) car. I promptly deleted everything and started over, but made a mental note of all I need to do whenever I get rid of my car.

 

I've already conceded a while back that maybe my garage door opener just wasn't compatible with Homelink. But I thought I'd give it one more chance after reading this post. Finally got it to work by following the 2 step process. That's what I love about this forum. You'll find answers to the most simple or difficult problems on your P-Car.

 

My issue is a little different from others mentioned here. I can erase the old codes, press the desired button and get the light slowly flashing, per the manual. Then, I take the handheld remote (with new battery), press the button, and hold it by the bumper near the tow hook area, and....nothing. No flashing fog lights no matter how long I hold it there. I happened by a dealer and let them try it, with the same result. The same system worked just fine with my Cayman, so I'm puzzled. Has this happened to anyone else?

 

I had the same issue on my first try. But you can try this.

Hold and press the remote button for 3 secs. then release. Then keep repeating it until you see the fog lights flash. Then I still had to follow the second step for it to work.

 

Thanks, I'll give it a try. Is it enough to have the ignition on, or does the engine actually have to be running?

 

I did mine last week with the engine off. The instructions above worked for me.
