VATS diagnosis uses electrical measurements, security-system data, wiring checks, and vehicle-specific procedures rather than guessing at parts. Ownership authorization is required, and we verify normal starting operation and warning-light behavior after the repair. Our mobile workshops are equipped with the same diagnostic and programming tools found at dealerships, allowing us to work on a wide range of vehicles, including many with advanced systems.
From traditional lock and key services to cutting-edge electronic systems, we have the capability to handle any challenge. Our technicians receive ongoing training to stay current with the latest automotive technology and industry best practices.
Time matters when your GM vehicle will not start. That’s why we maintain multiple mobile units throughout the Chicago area. Arrival and completion times depend on your location, vehicle, parts and current availability.
We believe in honest, upfront pricing. Before we begin any work, we provide a detailed quote so you know exactly what to expect. Our prices are competitive with other providers in the Chicago area, but we never compromise on quality or service.
VATS is the Vehicle Anti-Theft System used on many older General Motors vehicles. It reads a resistor value in the ignition key and allows the engine to start only when the value matches. GM VATS and related anti-theft systems, such as Passlock, vary by generation and vehicle.
A security warning or no-start can come from the key resistor value, the ignition wiring, Passlock components, a body-control issue, or another electrical fault. We diagnose the system first so that the actual cause is repaired.
It depends on the vehicle and the fault. After diagnosis we perform an authorized repair or a supported bypass only when it is appropriate for the vehicle. Proof of ownership is required before any anti-theft work.
The quote depends on the vehicle year and model, the anti-theft system generation, and what the diagnosis finds. Call (773) 521-7000 with the year, make, and model, and we will explain the quote before work begins.
