I just purchased a 2004 Crossfire 6 months ago. A great car and no problems until today. Went out to take for a spin and neither key would unlock or disable the alarm. Opened door and tried to start and the car shut down. Came home and researched it and was brought to this forum and this thread.

I wanted to give you my fix for what resolved the issue today. Tried the unhooking of battery and that alone did not work. Called my buddy who has excellent car knowledge. He said unhook batter again let sit for 5 minutes. Reconnect (alarm turned on again) and lock and unlock cardoor 3 times. After 3rd unlock the alarm went off and car started right up.

I hope this is able to help someone in the future.
