How to delete that damn Chevy passlock...

Recommended Posts

So I own a 99 Chevy Silverado with passlock, which is their ignition immobilizer system.....

Have you ever had the problem when you try to start your Chevy and it starts and dies.... then 10 minutes later it will start.... that is the passlock system slowly dieing.....

This started happening to me more and more till finally about 2 weeks ago my truck finally wouldnt start.... 

Knowing is was the passlock system I looked for a way to shut off or delete the system.... and this is what I found...


NEWROCKIES Inc. Passlock Bypass disables the ENTIRE system.

This works for early passkey, passlock 1 and 2.  . I don't think it works for passlock 3 because that's a transponder system...


Anyhow, this is a true delete unlike the passlock bypass module you would purchase to install a remote start system, that only replicates the key...

These are the directions for installation..










They set the switches but it's good to verify...

When I got done with the learn procedure the truck started right up....


I do recommend watching the voltage during the learn procedure, the ignition will be on for about 30 minutes... I had a charger and jumper pack keeping the voltage up other wise you have to redo the whole process from the beginning...


Also I have a remote start on my truck which originally had a key bypass installed.... I had removed the bypass incase it caused a problem.... with the new delete system I am able to use my remote start without the key bypass...

This product truly deletes the passlock system .... well worth the money, and customer support is great .... 

Hope this helps anyone with a similar problem...
