Third paragraph: Just clarifying - you purchased an updated HomeLink sensor for the Porsche and replaced the existing sensor? I see the cover in the front seems to be easy to remove and replace the sensor. I also have the newer Liftmaster garage door, Wifi etc. Door is 2020, car is 2005. Unable to program using the car manual instructions. Thank you.

 

I kinda gave up on getting mine to pair. I have a liftmaster gate and garage door opener. I ended up just putting the remote on my sunvisor.

 

correct. Bring your car into the 2010s and upgrade the home link module. Literally everything works as it should. I used a used module from a 2017 macan.

no garage opener made after 2015 will work with the stock module in our cars. The new module looks exactly the same and doesn’t even require any hardware removal (except for the bumper). There’s really no reason not to do this mod.

 

What Porsche part number is the 2017 Macan module? Thanks.

Where is the module located on a 997.1?

​​​​

 

Front bumper, under the trunk latch.

 

finally got around to doing this... found a newer audi module on ebay, $26 shipped... and lo and behold my homelink now works as it should --

 

What build date is on the module? What car model year did the module come out of?

 

 

Thank you. It looks like the build date is 1/25/2011. Advice earlier in this thread suggested the module needed to be built after 2015 (when the newer "rolling codes" spec was implemented). It's good to learn that a 2011 module will work. What kind of garage door opener do you have? Does it use the "rolling codes" security technology?

 

All you need is a homelink repeater to bridge the older UGDO with newer Security+2.0 signal. I have a newer liftmaster opener and my 2007 997 won’t connect. The homelink repeater solves the problem. Look it up. You don’t need to disassemble anything in your car.

 

I read somewhere that the HomeLink repeater/bridge makes it easier for a hacker thief to activate the opener, when compared with replacing the HomeLink module on the car. Can you confirm that's not the case?

 

If the hacker/thief is determined to open your garage door, they will open your garage door. I have two older cars, this is the perfect solution.

 

First off, those Homelink repeaters straight from the manufacturer have TERRIBLE range. Like really bad. I've used them before. Secondly, I think you underestimate how easy it is to copy a dumb RF signal. You can buy a part off of ebay for under $100 that will do the deed. Anyone with a tech background or under the age of 30 can figure it out. The rolling encryption is virtually impossible to do without a relay attack which requires a lot of coordination.

Everyone thinks they're safe until they're not. My entire life I've lived in the safest parts of the country, but these days anything can happen. Police aren't allowed to profile people anymore. Crime spreads anywhere a car can be driven. I'd highly recommend you take a more conservative view on safety.

Also, if you're OCD, why not replace the car's transceiver with a modern one? It's literally a drop in replacement, looks EXACTLY the same, future proofs your car, and you don't have to have this dumb repeater in your garage you have to wire up and look messy and lower your home's security.

 

if the hacker wants to get into your garage, doesnt matter what you have, they will get in. Dumb repeater, smart rolling codes no difference. There are many other easier ways to get into you home than through the garage. Secondly, when you have different brands of older cars, you cant’t always just replace the module. The range works great for me, never an issue. You might have gotten a lemon.

my recommendation to you is go back to a lock and key garage if you are that paranoid.

 

Not sure what industry you work in, but I've dabbled as an electrical engineer. Maybe you do something related and know something I don't, but there is a huge skill gap between the two technologies, I promise you.

Let's just agree to disagree.

When paranoia only requires you to do 30 minutes of work ONE TIME, you might as well do it. Otherwise you're just being stubborn because you have no mechanical skill, or you're lazy.

Also, don't forget the range issues and the ugly wiring mess you have to install in your garage. It's definitely the "I don't know how to work on cars" solution. Nothing wrong with that at all.
