Chevrolet Car Key Replacement: What Makes Chevy Keys Different
General Motors has used several distinct key technologies across Chevrolet's lineup over the years, and understanding which type your vehicle uses matters enormously for replacement. Basic double-sided cut keys were standard on older models and remain straightforward to duplicate. Starting in the mid-1990s, Chevrolet introduced VATS (Vehicle Anti-Theft System) keys, which embed a resistor pellet in the key blade — the ignition reads the resistance value, and a mismatch prevents the engine from starting. Later came transponder keys, where a microchip in the key head must be programmed to match the vehicle's ECU. More recent Chevrolet models use remote head keys that combine a cut blade with integrated fob buttons, while current trims — including the Blazer EV — use proximity smart keys that allow push-button start without inserting anything into the ignition.
Each of these technologies requires different equipment, different programming protocols, and a different level of expertise. Our technicians arrive equipped with professional-grade key cutters and OBD-II compatible programming tools that communicate directly with Chevrolet's proprietary systems. We handle Chevrolet key replacement on-site, cutting and programming to your specific VIN, so you leave with a fully functional key — not a blank that still needs a separate trip somewhere else. For Vancouver drivers who rely on their Chevy for the daily commute on State Route 14 or for weekend trips to the Columbia River Gorge, that efficiency is what matters most.
