The immobilizer system is responsible for preventing unauthorized starting of the vehicle. It works by recognizing only specific key or remote fobs programmed to the car’s computer. If the new battery in the key fob has not been properly programmed, it will not be recognized and the vehicle will not start.

To troubleshoot this problem, first make sure that the new battery is properly installed. Check for any loose connections or corrosion that may have caused damage to the circuit board. If all connections are secure, then check if the key fob is being recognized by the car’s computer system. This can be done with a diagnostic scan tool or a code reader connected to the OBD-II port. If there are no error codes stored in memory, then further investigations may be necessary to determine why the immobilizer system is not recognizing the key fob.

Key Programming Procedure

If further investigation reveals that there is an issue with programming of the key fob, then it will need to be reprogrammed for it to work properly with your vehicle. To do this, you must first diagnose which function of the key programming process needs to be addressed. This can usually be done by using a diagnostic scan tool or code reader connected to OBD-II port and reading any stored error codes related to key programming. Once you know which part of programming needs attention, you can then proceed with programing a new key using an appropriate software application designed for your make and model vehicle.

Start/Stop Engine Feature Investigating

The Start/Stop engine feature on 2013 Kia Optima vehicles allows drivers to turn off their engine while stopped in traffic without having to manually restart it when ready to move again.

However if this feature does not seem to work correctly after battery replacement then understanding about how this system works may help diagnose where problems may lie so suitable solutions can be found for fixing issues related with Intentimatic starter systems on these cars models..

The Intentimatic starter system uses sensors located throughout various parts of car’s engine bay such as throttle position sensor (TPS), crank position sensor (CPS) etc., which measure various parameters such as engine speed and load conditions so suitable amounts of torque can be applied during starting up process without causing damages due too excessive cranking forces applied by starter motor components etc.. In order for these sensors and other components related with intentimatic starter systems operate correctly after battery replacement they must first be checked thoroughly along with ensuring all connections are secure and free from any corrosion etc., before any further investigations into possible causes of intentimatic starter systems issues take place on these cars models..
