Detailed Product Overview

Standard Ignition US-529L is engineered as an OE-style ignition lock cylinder for vehicles that use a column-mounted cylinder.

This part is intended to replace a damaged original cylinder and restore normal ignition key operation on applications such as 2003-2007 Cadillac CTS and 2000-2005 Buick LeSabre. The coded cylinder adds a security layer by rejecting keys that are not matched to the proper R-code. This part cross-references 4H1013 and 53-2006 for the same application.
