Security system preventing car from running

Hello,

The best way to go is reset the system becasue you cannot bypass it. Here is a guide that will help you:

Leave the key "on" until the security light stops flashing then turn the key off then start the car within five seconds that should do it.

Please let us know if you need anything else to get the problem fixed.

Hi.

If you are talking about a factory alarm system, you will need to see the dealer. Honestly, I am not sure it can be bypassed. If it as an aftermarket system, try to locate its power supply and remove the power from the system.

According to forum rules, I am not allowed to tell you how bypass the security, even if I knew how. Any applicable trouble codes? When the problem occurs, you can check the starter circuit. Any testing, make sure the transmission is in park or neutral and the e-brake is set.

Is there a pellet in the key? There is information all over the web about bypassing that pellet, but, if the problem is elsewhere in the security system, that bypass will not work.

You could use a remote starter button on the starter solenoid, to see if it will crank? The leads on mine are not long enough to get me away from the vehicle, You have to be sure the transmission is in park or neutral and a functional e-brake is set. Even if you can crank it, if security issue, it still will not start, because of fuel enable.

Below is wiring for your starter.

Here is what you need, but as JDL stated, this will only resolve an ignition key sensor issue. The rest of the system has to be working and cannot be bypassed.

The most common failure in these is the sensor in the ignition lock that reads the key pellet. That would mean replacing the ignition lock with a sensor included.

That sensor can be bypassed. You would need a digital ohmeter to measure the resistance of the pellet in the key. Now go to Radio Shack and buy a resister of the exact same value as the key pellet. Go to the base of the steering column and locate the two thin white wires that go up to the sensor. Cut the two wires and solder the resister between the two ends coming from the harness. This will permanently bypass the sensor but not the rest of the system.

Below are the key resistance choices.
