Chevrolet Car Key Replacement: What Type of Key Does Your Chevy Use?
Not every Chevrolet key is the same, and the type of key your vehicle uses is one of the most important factors that shapes the scope of the replacement job. Older Chevy models — think mid-2000s Silverados, Cobalts, or Malibus — often use a basic laser-cut or double-sided metal key, sometimes paired with a separate remote fob for locking and unlocking. These are relatively straightforward to duplicate or replace on-site. Beginning around the mid-2000s and continuing through current production, Chevrolet started equipping most models with transponder chip keys, where a small electronic chip inside the key head must be programmed to match your vehicle's immobilizer system. If the chip isn't recognized, the engine simply won't start — even if the key cuts are perfect.
More recent Chevy vehicles, including the Blazer, Traverse, and the all-electric Blazer EV, often use proximity smart keys or key fobs that communicate with the car continuously. Losing one of these isn't just a matter of cutting metal — it requires programming via specialized diagnostic equipment. Our mobile technicians carry OEM-compatible programming tools and a broad inventory of key blanks so that, in most cases, we can complete a full Chevrolet car key replacement on the spot, right where you're parked in Brooklyn.
