Key Cylinder Holder BO-49753

Applications: Cadillac XTS, 2010 Buick LaCrosse, 2010 Cadillac SRX

Security enhancements made to comply with Thatchem requirements for high security locks have driven the need for a free-wheeling lock cylinder. BO-49753 is required to properly retain the free-wheeling door lock cylinder drum during assembly of the lock cylinder drum retaining pin. This procedure is done each time a door lock is replaced as the cylinder is serviced as a dis assembled kit. The lock cylinder is inserted into BO-49753 then assembled into a vice. Once secured, a hammer and drift punch are used to remove or install the retaining pin. Attempts to service the lock cylinder core retaining pin without BO-49753 may result in damage/breakage to the lock cylinder.
