Immobilized - Radio Swap

[Coldbourne]

Thanks for the replies.
From what I understand, leaving the key in the ignition for over two minutes will trigger the alarm immobilizer. I may be incorrect, but it is what I have read on the forums. Yes, the clutch is completely engaged, but good call. I have had the floor mat block it before and it would not start till I moved it.

The car locks, unlocks, all electronics are working. etc..
I found the security wire for the old radio, I am assuming I need to either disable it or run a loop-back on it so that it does not think the radio is stolen.

If it turns out not to be the immobilizer, I am assuming that there is a chance one of the fuses blew during the install. But I would like to rule out the immobilizer, if it is an easy fix, before I start troubleshooting the electrical system. Despite what the manual says about simply inserting the key back to 0 and trying to crank again, from what I am reading there sometimes needs to be a series of actions to unlock the immobilizer (i.e. all the windows up, top up, unlock the car with the remote, lock the car, unlock again, and then it unlocks).

I bought a Pioneer MVH-X580BS, but sadly no, still working on the issue.

What forums are you reading? I've never seen this stated here, never heard that about our 986s. Give me a link, I'd like to see what you are talking about.
I'm guessing a fuse, or relay is your issue. Back up and start troubleshooting from the beginning without the assumption that its the immobilizer ***unless you have some sort of aftermarket alarm system hidden in there somewhere.***

I have just changed the stereo head unit in our Boxster 2001 2.7 manual. I left the key in the ignition for at least 15 minutes and didn't experience any problems. I have had keys fail thought. The key is made up of three parts blade, remote control to operate doors/alarm and immobilizer tag. I would guess the electronics to communicate with the key fob when the key is in the ignition must be below the steering column. Maybe you have disturbed this wiring in fitting the stereo. have you tried the spare key?
I hope this helps.
Regards
Paul

I've never experienced this after leaving my key in the ignition and I've never seen this mentioned in the forums. Can you provide some links? I'd like to check out those comments. Thanks in advance.
