Kia Troubleshooting Questions? Ask a Mechanic
Hi Im David, sounds like it went into anti theft mode for some reason. if you have a meter, check the voltage of the battery. a fully charged and good battery should ALWAYS read just around 12.5 volts statically and not drop at all unless a door is opened or lights turned on etc... if it drops just sitting there watch it to see how far it drops. if it too much then the radio will lock out and you wont be able to start. you also want to check the voltage while the car is running. a good battery and alternator will read around 14.4 volts.
just checking in to see how its going
