No. The wrong key in the door did nothing. You can turn the key to the On position and follow the instructions on the dash. After 3 minutes it will say Wait 3 minutes, then Wait 2 minutes, then Wait 1 minute, then start car. This will Disable the Theft system so that you can drive to your dealer or mechanic. This may only work once, so don't shut it off. Good Luck TW
