To combat theft and enhance vehicle security, GM was one of the pioneers in the automotive industry to introduce chips in their keys, a practice they started as early as 1985. This technology was also integrated into the 2005 Chevrolet Colorado, so yes, your key contains a transponder chip. While it may be inconvenient when obtaining duplicate keys, it serves as a strong deterrent against theft. This safety measure significantly complicates starting the vehicle without the actual key. However, the drawback is that replacing these keys can be costly, reaching up to $150 each, far more expensive than typical key copies. To avoid these expenses, it is crucial to prevent losing your current key at all costs, even though it may seem like common sense, I still have trouble with it sometimes.
There is no electronic chip inside the key. If you take it apart and inspect, you'll see. Alternatively, you can confirm by removing the black portion of the key. Even without it, the key can still be used to start the vehicle. The security feature is actually a resistor integrated within the ignition switch.
