Chevrolet Sonic Repair Manual: Door Lock and Ignition Lock Folding and Non-Folding Key Cutting
High Security keys are available from the service parts system.
Obtain the key code from the security card or from the GM Dealer World, Parts, Key Code Look Up system.
If you have the key code and access to a Triax-E., BD Laser or other code key cutting machine from the GM Dealer Equipment Catalog, you may cut a new key.
If you have the original key and access to a Matrix S, BD Laser or other key duplicating machine, you may duplicate the key.
If you do not have a high security key cutting machine, order the side cut key from the service parts system. Include the key code in the NOTE field. Indicate the timing and the method of the shipment.
Inspect the new key operation in the lock cylinder. Ensure the new key operates effectively.
