How do you put the resistor in the passlock system on a Oldsmobile Alero


You don't say if the security light is lit ? Is it ? If not , it's not a anti-theft system problem . An the passlock system on your vehicle the passlock sensor is part of the ignition lock cylinder . No resistor ! If the security light is lit you need to have it check for codes . There are a number of DTC'S that can set .
DTC B2947
DTC B2948
DTC B2957
DTC B2958
DTC B2960
DTC B3031
DTC B3033
DTC P1626
DTC P1630
DTC P1631
DTC P1632

The Passlock™ system is provided in order to prevent vehicle theft if the ignition lock cylinder is forced to rotate or the ignition switch is operated while separated from the ignition lock cylinder case. The body control module (BCM) provides security system sensor power and low reference for the Passlock™ sensor. The BCM also measures the security system sensor voltage.
When the correct key is used to start the vehicle, a magnet on the lock cylinder passes close to the Passlock™ sensor within the ignition lock cylinder case. The magnet activates the security hall effect sensor in the Passlock™ sensor which completes a circuit from the security sensor signal circuit through a resistor to the security sensor low reference circuit. The resistance value will vary from vehicle to vehicle. The BCM will measure the voltage on the security sensor signal circuit and compare this voltage to a previously learned voltage. If the voltage measured is within the valid range, the BCM will send a class 2 message to the powertrain control module (PCM) to enable vehicle starting. If the voltage measured is not within the valid range, a class 2 message will be sent to the PCM to disable starting of the vehicle.

2003 Kia Rio want start because of anti theft system code


It has to do with your Pat's key for your program key that went with the old steering column there is a copper ring or like a wire type ring that went around the key cylinder on your old column I think you needed to switch that to the new column not just the key cylinder but the little plastic ring with a wire hook to it that goes around the key cylinder this will match your old key

If I buy a ignition at autozone for my Pontiac Aztek 2002 would just start with the key in the ignition I put in


If you don't change the key cylinder, it should work.
If you change the key cylinder, you would need to cut a new key with a blank that will match the chip in the old key.

How to resest a security light on buick 2002


security light comes on if the chip in your key isn't reading.. Possible issue are the pickup in the key cylinder is getting old and weak. a resistor that matches the reading of your key can be added to the bottom of the steering column where the orange wiring goes into a two pin connector and it will allow yo o bypass the security so it will start

Sometimes when i try to start my 91 firebird h security light comes on and car wont start i waik away for 10 min and car starts


the most likely suspect is the ignition key cylinder, there are 2 small white wires that go bad. there is no cheap easy way to repair it. the lock cylinder will need to be replaced along with new keys. The new keys have to match the resistor chip in the old keys, so a locksmith would be the best choice for the job. Of course you will want it diagnosed coreectly before just replacing parts that may not be the problem but thats the most common.

My mother has a 93 Pontiac Bonneville that will not start. It turns over, however there is an indicaiton on the dash board that says Anti-theft Device. How can we bypass this or get it to started?


Replace the ign lock cylinder. Or get new cylinder and plug it into the connector from the old lock cylinder at the lower part of steering column. Put old chip key in the new cylinder and hide under dash. Start car with a duplicate key from old key. No need to tear apart steering column ever again for this problem.

How do i replace ign. switch on a 99 alero


TO REMOVE IGNITION.FIRST TURN OFF RADIO.TO KEEP FROM LOCKING IT OUT.REMOVE NEGATIVE BATTERY CABLE.WAIT 20 MINUTES.THIS WILL DISABLE AIRBAGS.ALLOW THEM TO DISCHARGE.NOW YOU HAVE TO REMOVE THE INSTRUMENT CLUSTER.REMOVE THE TWO SCREWS SECURING THE IGNITION SWITCH.PUSH THE SWITCH ABOUT 1 INCH STRAIGHT BACK TO CLEAR THE MOUNTING BRACKET THEN LIFT IT UP AND OUT FROM BEHIND THE INSTRUMENT PANEL.DISCONNECT THE IGNITION SWITCH ELECTRICAL CONNECTORS AND THE IGNITION INTERLOCK CABLE.USING THE KEY TURN THE LOCK CYLINDER TO RUN AND PRESS IN THE PIN TO RELEASE THE CYLINDER THEN WITHDRAW THE CYLINDER WITH THE KEY.THE CYLINDER MUST BE REMOVED TO REPLACE IGNITION SWITCH BECAUSE YOU HAVE TO DISCONNECT WIRE TO THE IGNITION SWITCH. IN ORDER FOR CAR TO START YOU HAVE TO REPROGRAM NEW IGNITION SWITCH TO THE BCM AND PCM.TO DO THIS.TURN IGNITION SWITCH TO THE ON POSITION WITH ENGINE OFF FOR 10 MINUTES WATCH THE SECURITY LIGHT. WHEN SECURITY LIGHT EXTINGUISH.TURN OFF SWITCH FOR 5 SECONDS THEN START THE ENGINE.IF STILL DONT WORK TRY THIS PROCEDURE TWO MORE TIMES.IF YOU GET CAR RUNNING CHECK ENGINE LIGHT TURN ON CHECK FOR CODES P1630 P1631 P1632 USE CODE SCAN TO ERASE CODES IF CODES REMAIN LET DEALERSHIP CHECK IT OUT.THEY WILL HAVE TO ERASE CODES AND REPROGRAM THEFT SECURITY SYSTEM.

Will not start due to alam system, when i turn the key


your key has a resistor chip in the middle of it and two hair thin wires running to the ignition lock cylinder. there are two ways to fix it yourself, first track the two small orange wires from the lock cylinder down under the dash then A. pop the resistor out of your key and solder it between the orange wires or B. measure the resistance value of the chip with an ohm meter, buy resistors that match that value and solder them between the orange wires.

How do you change a key switch in a 2001 chevy impala, the factory keys wont turn in the switch


If your key is worn try getting a new one cut.
The ignition lock cylinder and keys do not contain any coded electronic components. The lock cylinder housing contains the coded electronic components. Changing an ignition lock cylinder or replacing a key is a purely mechanical process which does not affect the vehicle theft deterrent system. To replace an existing key, simply cut a new key to match the existing one. If no keys are available, the lock cylinder must be changed. To change the lock cylinder, simply replace the existing lock cylinder with one of the same type.
If you are unable to operate the ignition cylinder with a new key then you will probably need to replace the cylinder and switch.Replacement of the switch involves reprogramming
The system may be programmed with or without a scan tool.
There is a way to get the cylinder out without replacing the switch but this procedure should be performed by a qualified GM technician as it involves removal of the switch and some precise drilling.

Cadillac seville won't start


I've got an even cheaper and easier solution, instead of buying a new cylinder, find that plug and snip the orange wires going to the old cylinder.Then remove the resistor chip from the key and solder each of the the wires to each side. this will fool the car into thinking the correct resistor chip is in place, allowing you to use the original key or any copies with or without resistor chips. i just did this to my caddy and it roared to life! :)
