Key RFID and key bypass
 

I have only one key for an 01 S. I am afraid of losing the “key” so I have copied the blade to make a spare and in order that both work have attached the RFID from the first key to the ignition cylinder. I am comfortable with this solution.

I would like to install a remote start system. Currently the installation works only when the key blade is in the ignition cylinder and in the ACC position. After much research I believe that the ignition cylinder transponder antenna may be similar to a BMW, in which the ignition wires are hot when they key is in either ACC and crank? In other words, I think that they transponder antenna is not reading the connected RFID because it is not getting power except when the key blade is in the car in ACC.

If that is the case, then I can envision two possible solutions:

First and easiest would be to wire a relay to the transponder ?antenna? in the key ring. But I am a bit reluctant to cut that wire without confirming a previous bypass install, for fear of somehow screwing up the immobilizer requiring a reprogram of the CLU. Has anybody had a remote starter installed and if so how did they wire the key bypass?

The alternative would be to use a key bypass (I have a 556UW lying around). This solution leaves the exact same question: how to do the bypass install wiring. Additionally, I would need to copy the RFID in order to have the ability to start the car without the remote starter (since I would lose a key to the 556UW bypass). Does anybody know of a place doing RFID cloning?

I imagine quite a few folks must have had a remote starter installed. Thanks for any info that can be provided.

Not really. Most of us have manual transmissions and park in garages.

Remote starters can be installed in manuals and many of us are not blessed with the opportunity to live in Texas. Or even in the USA.

This topic has come up repeatedly in the past, but nobody has ever followed with details as to how they solved the issue. It’s a pretty straightforward question ... how to install a key bypass in a 986/996.

There's a reason for that: It is also teaching someone how to steal the car.

I seem to remember a detailed thread on how to use parts from another car grafted into the Boxster electronics to get the desired results. Since it didn't interest me particularly I immediately forgot all the details but a bit of searching might find it. I could be on the Rennlist Boxster forum also.

I am sorry, but that is a ridiculous and untrue statement. Learning proper wiring for a remote starter key bypass system does NOT equal teaching somebody to steal a car. A key bypass does not operate without a key (and properly coded RFID).

It is both TRUE, and correct. In order to steal the car, you need to bypass the immobilizer, EXACTLY what you are asking...............

Um wrong sorry try again.

A remote starter is NOT trying to bypass the immobilizer. It requires a key.

You obviously do not understand what a key bypass for a remote starter is: In order to start the car WITH a dealer programmed key you need to “bypass” the immobilizer by your definition. There is literally no difference Using a properly programmed RFID to start the car via the immobilizer does not facilitate its theft. There is an entire industry of legitimate companies built upon manufacturing remote start devices.

Once again, determining the proper wiring for such a remote starter does NOT facilitate its theft. It would not and can not operate without a programmed key.

You are attempting to hijack this thread with inaccurate hysteria.

Why do you suppose that there are no threads showing a completed remote start install?

No offense, but JFP knows his stuff. Cool down a bit :)

JFP and Particlewave are right.

Please explain to me how a information regarding how to correctly wire a remote starter facilitates theft.

Sorry, JFP, particlewave and you are all wrong. It strikes me that none of you understand the way these things work. Once again, let me repeat: a programmed key is required. Does starting a car with your key facilitate theft? These comments are a bit bizarre.

If you thing that is wrong, once again, please explain how. Is compustar facilitating vehicle theft?????

I think I understand where Clueless is coming from; I've owned a number of vehicles with both factory & aftermarket remote-starters. They are "secure" from theft in the sense that they still require a key. In every instance, the key must be inserted and turned while your foot is on the brake or the engine dies. (Not to mention the steering wheel must be unlocked).

However, from the perspective of a guy who has installed half-a-dozen of these remote-starters myself, JFP makes the correct statement that this is IN POINT OF FACT bypassing the anti-theft device that Porsche put in place. Wiring it so that it still requires a key is simply the option you'd take as the installer. Once it's by-passed, it's bypassed, until you wire it in such a fashion that it requires another device or mechanism to keep it bypassed.

So yes: drawing-up a schematic that would bypass the immobilizer for a remote-start DOES, in fact, teach us how to steal cars, despite the fact that a thief would still need to do the easy-part of circumventing the steering-lock.

I though Clueless wanted to stand in his living room and start his car out in the driveway with his key fob. I got a buddy can do that remote start thing with his truck.

uh.... yeeeesss...... ? That's indeed what we're talking about.

Both of these paragraphs are close but not quite correct.

The key bypass REQUIRES A KEY.

Second, it is NOT drawing up a schematic to bypass the immobilizer. That is NOT what I am requesting and the whole idea is a bit ridiculous. The key bypass uses a key and RFID. Just like when you start your car with a key normally. It USES the factory immobilizer (like a normal crank with key). Asking how to wire the car properly ... is how the factory transponder ring is wired in NO WAY facilitates theft. Wiring it so it still requires a key is not an option. It is always required. It’s how a key bypass works (at least in this Porsche ... some other cars, including the cayenne, can do so through firmware. But even that does NOT bypass the immobilizer).

Once again, these comments suggesting that I am looking for how to wire around the immobilizer are simply not accurate. They belie a fundamental misunderstanding of how a DEI 556U module operates. And getting proper instructions for how to install and wire a 556u would not facilitate theft any more than getting instructions for how to wire up a car audio system.

I'd point-out that you came here ASKING us.... and now you're TELLING us. :cool:

here's a direct cut-n-paste from the 556U description: " The 556U bypasses the immobilizer system only while the remote start is in use, maintaining the factory system’s integrity. "

This is where you nod your head and say "see? I told you so!"

And then that's where I say "wait... read that first part again..."

"The 556U bypasses the immobilizer system...."

And then I explain to you that DEi has chosen to provide a product that takes-away from you, the installer, the ability to forgo the immobilizer altogether. But that's not to say that it can't be modified (I've never dicked-around with one. Never needed to)

So you're sorta missing the point we're making, which is that once that unit is bypassed, all bets are off.

Again: You came here ASKING. 'sall I know.

You apparently (think) you know what you’re talking about, so do it.

What are you asking us for? Get it done! ;)

Please see the first post in this thread prior to hijack

Let me try to post this without being hit by the ******************** storm that has irrupted.
Here is the thread I was referring to above.

Good luck...

Keyless entry and remote start are not the same thing. ;)

You don’t. Moving on...

And why is that? Because you don’t know how and you therefore decided???

In the meantime, thanks for trying to be helpful elgyqc. While the post wasn’t directly on topic the poster was a pro in the 12V industry, exactly the kind of guy who would understand what I’m talking about and might know the answer. So I PMd him and hope that he is still around these parts.

In case anybody pops by this thread and does NOT want to talk about having a summer car, living in Texas, car theft histrionics, or the inappropriateness of remote starters in manual transmission vehicles, my technical questions remain.

Specifically:

1) Does anybody know how to install DEI 556U in 2001 Boxster? Eg, is the wiring Euro style, non-euro, or some other way (there’s a VAG tech bulletin from DEI)? Which transponder wire is cut?

2) Can the factory transponder ring be directly powered during crank (and ACC) to read the required key (if inserted in the ignition cylinder).

Wow. You must really be a ton of fun at parties.

I was going to offer to help until I saw how rude you were being to JFP. He’s a valuable member and I think you could have approached it better.

Good luck! :D

The transmitter antenna in the 986 is a passive component.

I think that should answer your initial "hacking the immobilizer system" question.

Yes, that info may help. If it’s just a passive antenna does that = there’s no reason I can’t just directly power it via relay? (that’s the core of the issue ... I’m not trying to “hack the immobilizer”; instead I am trying to enable/power the factory transponder antenna ON to look for a pill on remote start).

Is the passive antenna powered with constant 12V positive? And would it matter which side (which of the two wires) was powered (via relay)?

I been needing a new password for my computer at work. "Cluelessthe****************************1" At least 15 letters and easy to remember.

WTF. Really?? Was that necessary?

90% of the replies in this thread have not been necessary.

Make that 95% . . . . . . .

:p

97% now. :rolleyes:

as mentioned the antenna itself is passive, but it is connected to the immobilizer module. the immobilizer module is powered by the orange wire coming from the ignition switch.
here is a diagram of the immobilizer module. http://986forum.com/forums/uploads02/11568227407.jpg

Easiest solution - buy a second key and have a dealer or indie program it for your car.

I am not sure I should get involved in this, but I think I might know how a remote start could work. Basically, you would need another programmed transponder. That would be put in another reader coil in the remote start that would be relayed to the coil reading module instead of the original coil when the remote start was activated via its transmitter. So, unless the remote start transmitter was used, it would function normally. If the remote start was used, you would still need the mechanical key to unlock the column and drive the car. I would assume there are interlocks for the parking brake and some sort of neutral safety mechanism.

So, the only real danger of cars being stolen would be by having that extra transponder in the car that is used by the remote start. You would need to know it has the remote start and where it is, then remove the transponder and put it in a key that would work in the lock so you could use it as a normal key. If the remote start's transponder was glued in, it would be extremely difficult to do this, to the point I would say the risk would be negligible.

As for the remote start, it would need to energize the 86s terminal when switched over to the remote start transponder. That would make the coil reader module read the transponder and start the transponder authentication process. Once that is done, you energize the ignition and then starter.

All that said, I have never installed one of the devices that is mentioned, so I have no idea how the configuration needs to be set up to get it to work or if the device in question can do this, but I would bet it can. I personally wouldn't put one in my Boxster, but YMMV.

These are all different points of view and opinions. I can't agree with any, but we do have a stubborn one.
