The systems in use that do this usually use an RFID-type chip in the key fob, which is read by a coil around the ignition slot, and the result is sent to the immobilizer telling it if the key matches the vehicle.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1Original post

Bought a 2001 986 that was running until it was left open in the rain. The original M535 was toast. Many fried components. Bought an immobilizer that powered up a lot of stuff when plugged in, but will not start the car. Have the original key. What is my next step?

POST 2Original post

Next step? I'd suggest visiting https://www.planet-9.com/forums/new_members/ and introducing yourself and your car. We usually reply better when we know who we're responding to. Your username suggests you have some experience with British cars. Porsches are quite different (as I'm sure you're finding..) I know the web is a place where people ask questions and get instant answers. That usually isn't how forums (at least this one) work. We actually think a bit about your issue and might ask some questions before offering answers. I'd suggest also reading: https://www.planet-9.com/threads/be...ting-a-technical-question-please-read-this.254563/?post_id=2217923#post-2217923 Now, as to your problem, I have no direct information on how the 986 immobilizer works.. but in general, these are matched to the key. The key sends a signal to the immobilizer that it's an original Porsche key for this vehicle, and it's OK to start the car; it's not stolen. The systems in use that do this usually use an RFID-type chip in the key fob, which is read by a coil around the ignition slot, and the result is sent to the immobilizer telling it if the key matches the vehicle. If this is the case - and again - I have no direct experience with that era immobilizer - you likely need the keys that match the immobilizer to get that chip. Some questions: Does your 986 have keyless entry (ie - lock/unlock button on the key) - if so - does that work? What is a M535 (aside from a BMW model of the mid-1980s)?

Quotes source post: 2217923

M535 is the immobilizer package under the drivers seat that gets wet and stops everything.

POST 4Original post

Interesting - typically that would have a PN starting with the model it was introduced in, in the case of a 986 immobilizer, it was first used in a 996 series 911 . I've never heard it referred to as an M535.. is that on the unit?
