Hopefully someone has an idea why this is happening. I recently switched out all the parts of my original key fob (transponder chip, blade, etc.) into an new key fob case. The remote operates the door locks but when I try to start the car it runs for about two seconds and then quits. It does this three times and them the starter seems to disable because when the ignition is turned nothing happens at all. I then used the original spare key and everything works fine. What am I missing? BTW, car is a 2005 SRT6.
