How to disconnect passlock in a 2003 Chevrolet impala


You can't. Older GM's could bypass the key with a resistor, But it still had to have the security disabled. Yours is I believe a passlock III. You'll have to fix the problem. Could be as easy as a new key and a relearn procedure. Have the codes read.

Security light stays on


Annette: According to http://www.realworldautomotive.com/shoptalk-questions-1999-chevy-tahoe-security-light-on-dash-t467.html : " Passlock is a second generation General Motors' theft deterrent system. With the use of a Passlock sensor (mounted in the steering column) the Passlock system can determine improper ignition key and lock cylinder operation by monitoring magnetic fields emitted by the lock cylinder assembly. Once improper operation is confirmed, engine startup is disabled.
The Passlock system eliminated the resistor chip mounted in the ignition key used by the previous Passkey system, including the headaches and expense that went along with it.
Passlock is a subsystem of the vehicle's Powertrain Control Module. The Passlock sensor sends a signal to the Passlock control module. The Passlock module reads this signal and sends the appropriate information to the Powertrain Control Module. If the ignition key and lock cylinder operates normally the engine will start as usual. If it was operated improperly the Powertrain Control Module will be directed to disable fuel injector operation, prevent engine startup, and there will be a diagnostic trouble code set in the Passlock Control Module's memory.
I just wanted to give you an understanding of system operation. It's gonna require the correct scan tool for proper diagnosis. Weak links are the circuits to and from the Passlock Sensor in the steering column. It's a very sensitive signal and can be easily affected by shoddy electrical connections.
If a scan tool displays diagnostic trouble code B2960 (Passlock sensor voltage out of range), the next step would be a resistance check and a complete inspection of connections and wiring involving the sensor. Pay the diagnostic time at a heads-up auto repair shop."

Passlock is the anti theft that is built into your car from GM. If the car is not stalling while driving or having starting issues, it is probably not a problem. It might just be an informative light. If it ends up making your car die or not start, it is a passlock failure which can be expensive.

My 2004 Chevy Malibu passlock keeps locking


you can easily bypass the security system entirely. There is a great write-up here http://newrockies.ca . That was the only solution that saved my Park Avenue.

GM Passlock I & II Information

Please study the following information carefully WHEN INSTALLING REMOTE START systems on a 1996 or later GM car or truck.
Introduced in 1996, GM has changed the VATS anti theft system to Pass-Lock system. This is a similar device to the VATS system, in that there is a resistor present during the start cycle. However, in the PASSLOCK system, the resistor has been placed inside the ignition switch, instead of the key. See the GM V.A.T.S page for more information.
To remotely start a car with this feature, you must bypass the PASSLOCK system. There are two methods of doing so.. The first, is to permanently bypass this system. This is the easiest method for accomplishing your task. The second way, is to temporarily bypass the PASSLOCK, by introducing relays into the system, which retain all of the features of the system, while allowing your remotes start module to bypass it automatically during a remote start cycle.
Vehicles effected
(1996 and newer): N & J body cars, such as
Pontiac Sunfire and GrandAm Passlock-1
Chevrolet Cavalier Passlock-1
Buick Skylark Passlock-1
Oldsmobile Achieva Passlock-1

1997 or newer
Chevrolet Malibu Passlock-II
Oldsmobile Cutlass Passlock-II

1998 or newer
All trucks , SUVs and Vans Passlock-II

It is important to pay special attention to the fact that there are many different ways of achieving the same goal. There are actually 2 different Passlock-II systems. On the next page, there are tests to establish which type of passlock-II your car has.

Relays shown are standard automotive 5 pin spdt relays, available from IEI.
A multi meter is required to measure the resistance values. Accuracy is important within 5%.

Once the value of the resistor is measured, a resistor of the same value +/-5% must be purchased (Radio Shack, for example). You can also use a Potentiometer (POT), which can be adjusted to the same value of the resistor in the ignition switch.

pslc1.gif Passlock-I bypass procedure....

1: Remove the top and bottom shrouds from the steering column.
2: Find the 3 wire ribbon cable, coming from the ignition switch, containing White, Black, Yellow (Sometimes White, Black, Black). These are THIN wires.
3: Locate the Black 6 position connector on the LEFT side of the steering column, right above the ignition switch position. There is a BLACK (Thin) wire in this connector, called "Bulb Test", which shows Ground with ignition in the Off position, OPEN in the "Run" position, and GROUND in the "Crank" position.
4: Turn the ignition switch to the "Run" position. Do not crank the car.
5: Cut the Thin Yellow wire and strip both ends.
6: Without cutting the Black wire, expose some of the copper.
7: Using the ohmmeter, measure from the Yellow wire (the end coming from the ignition switch), to the exposed Black wire and record the value. Measure more than once to assure you have the right value.
8: Acquire the same size resistor and 3 relays, and perform the connections shown in the diagram below.

pslk2.gif PASSLOCK-II bypass procedure

There are 2 types of Passlock-II systems. To determine which system you have, follow these instructions;

1: Locate two wires, which are THIN and are in the main ignition harness.. Orange/Black (or Black) and Yellow.
2: Cut the Yellow wire, and strip back some of the insulation from the Orange/Black (Or Black) wires.
3: Turn the ignition to the "Run" position ( don't crank the starter). Measure and record the value measured from the KEY SIDE of the Yellow wire, to the Black/Orange wire.
4: Turn the key to the "Crank" position and release. Now read the value again.
pslk3.gif5: If the value changed, follow "Method#1". If the value stayed the same, follow "Method#2".

Security light flashing and car won't start now


does it start at all, or does it run for about 1 second and shut off? if the latter, then it's the passlock system, and he could have a defective key or security module. the keys have a predetermined resistance value which activates the passlock system to prevent hotwiring. If it is the passlock system, then sometimes you have to wait 15-20 mins for it to reset before starting the engine.
