Get your key turning and power moving through the ignition circuit again with the Standard Ignition Ignition Lock Cylinder and Switch (US-449). It installs as a direct-fit replacement for the 2001-2004 Chevrolet Tracker along with the 2001 and 2003 Suzuki Vitara, combining the mechanical lock cylinder and the electrical switch in a single assembly.
Two jobs, one unit: the lock cylinder accepts and reads the key while the switch routes power through the off, accessory, run and start positions.
Manages the starting circuit: in the start position it signals the starter, and in the run position it feeds the ignition and accessory circuits.
Direct-fit replacement: made to install on the listed applications.
Signs the original lock cylinder or switch may need replacing include a key that sticks or won't turn, no response when the key is turned toward start, or intermittent loss of power to the ignition and accessory circuits. These symptoms can have other causes, so diagnose the ignition circuit first; if a failed lock cylinder or switch is the cause, this US-449 assembly replaces it.
