Key Release Interlock Actuator

WARNING: This page is about a different car, the 2008 Mercury Mariner and 2008 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

The key release interlock actuator (also known as the key removal inhibit solenoid) is an electronically controlled solenoid that prevents the ignition key from being removed from the ignition cylinder unless the transmission selector lever is in the PARK position. The actuator is part of the steering column lock module and is mounted opposite the ignition cylinder. If a new actuator needs to be installed, then a the lock module must be installed. Refer to Steering Column Lock Module .

When the transmission selector lever is placed in a position other than PARK, the park detection switch closes and the key release interlock engages. This prevents the ignition key from being removed from the ignition cylinder.

When the transmission selector lever is placed in the PARK position, the park detection switch opens and the key release interlock disengages, allowing the ignition key to be removed from the ignition cylinder.
