Immobilizer car wont start after alarm has gone off

Subaru Keyless Entry Security Alarm Immobilizer Key Remote Start Systems...

start with this link its explains how the security system works

Check the ignition barrel electrical connections before doing anything, they are a common fault and do detach and cause wiring shorts, this fools the vehicle into thinking its being stolen. There is also a unit situated behind the dashboard clocks which are also a known common fault, its part of the immobilizer and also are well known to short out when being jump started with leads or a booster pack, it isnt coded. Hope it helps good luck.

Subaru Keyless Entry Security Alarm Immobilizer Key Remote Start... go to that site and scroll down it has detailed instructions on the factory alarm systems

just run as fast as you can when the alarm goes off. explain to cops

Sounds like an immobilizer/alarm issue...only way to properly diagnose is with a Saab factory scan tool...unfortunately..
Try another key if you have one....also lock and unlock the vehicle a few times with the key fob...or door key to insure the alarm/immobilizer has been turned off.

Hope this helps!

Unplug the Battery terminal and then charge your battery and then reinstall the battery with your key in on position. Hope this helps

its the immobilizer reset switch, Its used for if your alarm is activated and your car wont start, you can follow a string of instructions(involving the button) to reset your alarm! hope this was insightful

disconnect the neg battery terminal for 30 sec leave drivers door open, reconnect and start your car, if the alarm turns on after conecting battery use your key in the drivers door and unlock

BMW E36 immobilizer Hope the following will help. Had similar problems. The transmitter buttons on keys is for central locking and alarm. Inside the key at the front there is a small electronic/magnetic chip that looks like a block. About 8mm long, 2mm deep and 4mm wide, not connected to any pc board. This is the immobilizer. It must match the receiver that is located behind the ignition switch. If it is loose and too far away from the receiver it won?t deactivate it. If you made a spare key it will switch on electrics but won?t start the car. If you don?t have an immobilizer chip any alarm shop will be able to program a new chip or install a new pair for your keys. There is a way to disable the immobilizer but rather have it fix and protect your car. I read an article somewhere (perhaps bmw e36 blog) of people removing this immobilizer. Good luck

open the door or boot with the key
this earths the immobilizer out and will restart the alarm
