PI0091B

Bulletin No.: PI0091B
Date: Apr-2015
Subject:
Intermittently Key Will Not Rotate in Door or Ignition Lock Cylinder
Models:
2008-2016 GM Passenger Cars and Trucks
Equipped with a “Side Mill” Key
Attention:
This PI also applies to any of the above models that may be Export vehicles.
This PI has been revised to add the 2013-2016 Model Years and update the Warranty Information. Please discard PI0091A.
Condition/Concern
Some customers may comment that intermittently the key will not insert fully or rotate in the door or ignition lock cylinder. With repeated attempts and additional
force, the key will then insert and operate the lock.
The above vehicles use a new style of key called a “side mill” key. Debris (1) may build up in the key groove preventing full insertion of the key. A properly
cleaned key (2) will be free of any debris.
Important: Some side mill keys have the cut along the keys edge as opposed to the central cut shown in the photograph. Keys with either physical appearance
may collect debris along the slot.
Recommendation/Instructions
Clean the debris from the groove with a fine wire brush and a soft cloth.
Additional Information – Ignition Cylinder Torque-Lock
If the customer's key is free of debris as presented and the original concern was limited to the ignition lock cylinder, your customer may be experiencing torque
locking of the ignition cylinder. If the key seems stuck in the LOCK position and you can't turn the key, then turn the steering wheel left and right WHILE you turn
the key firmly. Turn the key only with your hand. NEVER use a tool to force it as you could break the key or the ignition switch.
To avoid this concern when parking, after the vehicle has come to a complete stop, let go of the steering wheel and allow the steering system to relax before
turning the key to the LOCK position and removing the key.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may
occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools,
safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that
your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
