Yes, I have seen the older yellow snake head keys (where can I find one?), they basically look like the logo on the hood. I dont think they were made in any of the newer (97 and up) colors. Then I have seen the newer snake head keys, where its cut out and has the word viper along the top, these I have seen in red, black, and blue so I thought maybe they made silver, yellow, sapphire etc. My key is the cheapo plastic chrysler star, just like my friends grand cherokee.
