To reset the immobilizer on a Chrysler 300, follow these steps: Turn the key to the on position for 10 seconds, then switch to the off or lock position for 10 seconds. Repeat this process, then turn the vehicle on to complete the reset. An immobilizer is an electronic security device in vehicles that prevents the engine from starting without the correct key (transponder or smart key). This feature deters car theft by disabling the engine if the correct key is not present. Typically, immobilizer issues can be resolved by replacing the battery in the key fob. Many transponder keys rely on a small battery to transmit the security code to the vehicle's immobilizer. When replacing the battery, be cautious not to damage the internal transponder chip.
