Standard Ignition Ignition Lock Cylinder and Switch,Ignition Switch P/N:US-668
Replace a worn ignition lock and the switch behind it in one assembly with the Standard Ignition Lock Cylinder and Switch US-508, a direct-fit replacement for the 1999-2003 Acura TL and 2001-2003 Acura CL. This ignition switch with lock cylinder combines the part your key turns with the switch that sends power to the ignition, starter and accessory circuits as the key moves through its positions.
Signs this part may need replacing include a key that is hard to turn or will not turn, a no-crank or intermittent-start condition, or dash lights and accessories that cut out while driving. If a worn lock cylinder or ignition switch is the cause, this assembly replaces both; diagnose the ignition circuit before ordering, since these symptoms can have other causes.
