My immobilizer kicked in on its own (no electrical power at all). A couple lock/unlock on the fob and a couple of door open/close/lock/unlock got the alam going. I clicked unlock to stop the alarm and then turned key to on and I had dash lights. As soon as I turned to ignition everything died again. I did this several times over with the same results each time. I googled my problem and at a site before I found this one suggested disconnecting the battery for 10-20 mins to allow the immobilizer to reset. When I reconnected the battery the alarm came on and I used the fob to shut it and tried the key. It worked and I have started and stopped the car several times. But now there is a rough slower idle (between 500-600) which has occurred before and then becomes the regular 800 idle after some miles of driving and some hours. I haven't driven it yet so don't know if it will go away this time. Any ideas for a fix - I don't want to get stuck in West Podunk if the immobilizer refuses the reset trick. Thanks.
