JK:
On this vehicle and system, there are no radio codes to enter. The radio should not lock up after a
battery disconnect. The system uses the VIN of the car for radio theft security. The loose
connection at the battery may have caused a malfunction in the radio and needs to be diagnosed
with a scanner. The radio Theft on this system must be re-learned through the dealer scanner if
locked.
