2008 Chevy Silverado used-cluster install triggered Passlock — dealer had it for 3 weeks
Used-car dealer cleared Passlock in 4 days
The problem
An Arizona used-car dealer bought a 2008 Silverado at auction with a known cluster issue. They installed a used cluster from another Silverado, but the truck refused to start — Passlock triggered immediately because the donor cluster's anti-theft counter was set and didn't match the truck.
What other shops said
The dealership had been holding the truck at a local Chevy dealer for 3 weeks waiting for diagnosis. The Chevy dealer wanted to swap the BCM AND the cluster, then re-program everything — quoting $1,400 + tow. The truck was costing the dealer $40/day in lot rent.
What we did
Used-car dealer shipped both the donor cluster and the truck's VIN info. We bench-programmed the cluster to the truck's VIN + cleared the Passlock counter + synced the mileage to the truck's ECU-stored value. Shipped back via UPS Ground.
Outcome
Dealer installed the cluster in their service bay in 20 minutes. Truck started on first crank. They listed it for sale that same week. Net win: 17 days saved vs the dealer route, $1,200 in lot rent + service costs avoided.
“I now mail every GM cluster swap to AML before I even drop the truck. $200 + 4 days vs $1,400 + 3 weeks is not a hard math problem.”— Used-car dealer GM, Phoenix AZ (verified)
