hahaha you and many others.
You can look at it in a good and a bad way.
The good way is that because your car didn't have the transponder in the key head, it was cheap and easy to recover some keys. But the bad way is, your car security sucks and it really is that easy to steal. Believe me, it was my job
If your car did require a transponder key to start, you would've been looking down the barrel of a minimum $350-500 for a set made.
