Key Lock Release
Vehicles with an automatic transmission are equipped with an electronic key lock release system. The key lock release is designed to prevent ignition key removal unless the shift lever is in P (Park).
The key lock release is always functional except in the case of an uncharged or low voltage (less than 9-volt) battery. If the vehicle has an uncharged battery or a battery with low voltage, try charging or jump starting the battery. See Jump Starting .
If charging or jump starting the battery does not work, locate the hole below the ignition lock. Insert a flat bladed tool or another key from the key chain into the opening. When the lever can be felt, actuate the lever toward the driver, and remove the key from the ignition.
