1999 Chevy Tahoe with passlock problem?

Answer 1

turn key to start position for 10 minutes and it will reset passlock

Or, once you're tired of being stranded for 15 min every 6 weeks or so, try the following:

Here's the "fix" I just did for my 99 tahoe. Took the cover off the steering column, unplugged the sensor from the cylinder *while* the car was running. it's a 3 wire plug red w/ white, orange w/black and yellow. From then on, the car will always start and ignore the sensor. The only negative is the security light stays on. But, I plan to just remove the bulb. Replacing the BCM only postpones it from happening again. Check out the following links. As an electrical engineer, I also believe there is an inherent design flaw because there are too many issues reported. Good luck.

This will work ok until the battery goes dead or is disconnected. Then the system will default back to normal will not start until the 3 wire plug is connected again...

I have tried the 10 miniute thing and the security light still was on and the van would not start?
