2001 GMC Yukon MECHANICAL-KEY Replacement - Fast, Affordable & Professional
She called around 8:45 at night from a parking lot near San Jose Creek in Goleta. Her 2001 Yukon had been sitting for two hours while she was in a night class, and now it would crank but not fire. Dash was lit up with "SERVICE THEFT DETERRENT" and the security light was on solid.
She had already tried the usual wait-ten-minutes trick someone told her about on a GMC forum. Twice. Nothing changed.
I got out there and checked the basics first. Battery was fine. Key turned smooth, no binding in the cylinder. The problem was the Passlock II sensor inside the steering column. The hall-effect sensor had drifted out of its resistance range, so the body control module was reading the wrong value and killing fuel injector pulse. The BCM thought someone was stealing the truck.
I pulled the lower column cover, tested the Passlock sensor leads at the BCM connector (pins A10 and A11 on the blue connector), and confirmed the resistance was floating instead of steady. Repaired the sensor circuit and ran the relearn procedure. That is the one where you leave the key in ON for ten minutes, off, repeat three times. Thirty minutes of watching a dash light blink.
She sat in the passenger seat reading her textbook the whole time. When it finally started, she just closed the book and said "okay" like she had been waiting for a bus.
Drove home that night. No tow, no dealer visit the next morning, no new parts she did not need.

Five Stars for Fair GMC Prices
What honest rates sound like in reviews
“This is the only locksmith anyone should ever call. I am still shocked at how fast he arrived and the price was hundreds less than other quotes I received. Honest, professional, and extremely efficient.”
“Locked out on a weekend night and everyone else wanted $300+. EZ Car Keyz sent Roman late at night for much less. He worked for over an hour and did not give up until the door opened. They even made a new key on the spot.”
“I had two Subaru key fobs made and Marco provided excellent service. He stayed persistent through multiple part orders to make sure everything was correct. Very thorough, punctual, and great communication throughout.”
