Turn off for 5 seconds then Leave in ON position for 10 min, crank it but not start it.then off for 5 seconds, then do the 10 minutes in ON position again then off.crank it.off for 5 seconds and ON position again for 10 min then off, then crank it and off for 5 seconds then ON for 10 minutes then off. Key turned on then try to start but don't let it, just crank it. It is that Passlock needs to be relearned. People this is happening with many models of Chevy and even Hummers. If you have performed these steps correctly, your Passlock system will no longer give you any problems! Once that is done, be sure to tape the exposed cut wire that leads to the ignition barrel. Now you take the cut wire that leads toward the Passlock module (NOT toward the ignition barrel) and connect the other end of the resistor to this wire, being sure to tape it to protect against shorting.

Protect this wire by taping over the exposed metal. You may solder this connection if you desire. Once you have assembled the resistors so they represent the correct value, tightly wrap one end of the resistor through and around the exposed copper of the black wire. You can be within about 5% of the value, and it will be accepted by the passlock system as genuine. Next, arrange one or more resistors in a chain so that they add up to the value measured while cranking the starter. While doing this, crank the starter and note the resistance reading you get on the multimeter. Hold the other probe to the ignition side of the wire you cut in the earlier step. stick one probe into the exposed copper in the black wire, being careful not to touch it during the resistance test you are about to do. Now grab a reliable multimeter and set it to read Ohms. Next you must strip some of the insulation away from the black wire, exposing the copper inside. Strip both ends of the wire, so you can reconnect them if needed. They can also be yellow, red/white, and black.Ĭut the orange/black wire or the yellow wire, depending on what you have. Usually, they are orange/black, red/white, and black. To find these wires, look for three wires that at some point are wrapped together, coming from the ignition barrel. The easiest way to bypass the Passlock 2 system is to place a resistor between the passlock sensing wire and the ground reference wire. Images are from the same site as the link and credit to the guys at as well as an interesting schematic that may offer more of a permanent solution.

Try restarting it, you will see the red security light on, but that can be removed with the LED mod how to.Ĭheck on here for more info. Step four: Shut off the truck, You’re done! Step Three: Cut this wire in half, and electrical tape both ends. It will be with other wires that are white/colored stripe. We are looking for the wire that is White with a BLUE stripe. We will be working with the right side of this plug. You will notice that on the side closest to the front seats, the plug is pretty much split in two.

Open your driver door and stick your head on the floor near the gas and brake pedal and look up, it will be the big white plug staring you in the face. Step Two: Locate the plug pictured below, The plug is under the dash near the steering column. Step One: Start the truck, leaving it in park, and running during this process. The only other way that I've read about is the 'White/blue' method. There is even a DIY plan for sale that they say can defeat the passlock GM will not disable it. There are a few commercial devices like this one. Wow, it looks like there is a whole industry built around defeating the passlock. For those who are willing to call here is the number. It could even be considered a safety issue. After all, this is a design flaw and I feel GM should be responsible for correcting it as they would any other design flaw in any of their models. So I think if enough people called to complain, they might consider an open recall. I told them that this is a design flaw and does not work as intended and that many other people are having the same problem. I asked to speak with someone in the engineering department to no avail. They advised that I should not try this, and should take it to a dealership.

It has become aggravating as well as very inconvenient! I called the Chevrolet Assistance Line for advice on how to go about bypassing the passlock system. Would just like you to know that I, along with many others, am having the same problem with the passlock system.
