I lost my ignition key the other day, i did not know how the alarm worked on the new 06 300C, but i do now. I used my hidden door key to gain access to the vehicle the alarm sounded for quiet a while before re-arming itself. Are there any good places on the net to purchase a factory ignition key for the 300C? After returning home and getting my other switch key, i received a call that my other key had been found. I'm still thinking about getting another key.
