Does the 2005 Chevy Colorado have a chip in the key?

In order to reduce theft and better secure their vehicles, GM was one of the first automotive manufacturers to install chips in their vehicles' keys. This was done as far back as 1985. The 2005 Chevrolet Colorado is no exception -- yes, Your key does include a transponder chip. While this can be a pain when You're getting duplicate keys, this is a huge deterrent to theft. It's a safety feature that makes starting the vehicle without its actual key almost prohibitively difficult. The downside is that instead of paying a few dollars for a replacement key, You're shackled to options that can cost up to $150 each. You can mitigate this by doing everything within Your power to not lose Your existing key; seems like common sense, but I find it pretty hard at times.
