How to disconnect and remove the ignition lock assembly and ignition switch on Lexus RX350?

Disconnect the cable from the negative terminal of the battery. Remove the upper and lower steering column covers. Disconnect the electrical connector from the ignition switch by depressing the release tab and pulling off the connector. Remove the ignition switch retaining screws and detach the switch from the Ignition Lock Cylinder housing, then installation is the reverse of removal. Place the ignition key in the ACC position. If the vehicle has an immobilizer system, disconnect the electrical connector from the immobilizer module, then slide the immobilizer module and the Ignition Lock Cylinder illumination ring as a single assembly. Use an awl or punch to depress the Ignition Lock Cylinder retaining pin and remove the Ignition Lock Cylinder from the housing by ensuring the lock cylinder is in the ACC position, inserting the awl or punch into the small hole in the housing, pushing it in to depress the retaining pin, and pulling out the Ignition Lock Cylinder. To install the lock cylinder, depress the retaining pin and guide it into the housing until the retaining pin extends back into the locating hole. The remainder of installation is the reverse of removal. Remove the knee bolster panel and center trim panel. Using a trim tool, carefully pry the switch panel out from the instrument panel, then disconnect the electrical connector from the engine start switch and remove the switch from the back side of the panel, with installation being the reverse of removal.

Lexus RX350 Ignition Switch

Lexus RX350 Ignition Switch provides drivers the direct power-up point, which wakes up the engine and components with a simple turn of a key or the push of a button. Earlier Lexus models in the RX350 line applied a column-mounted Ignition Switch that accepted a chipped key, allowing the computer to verify the code before routing battery current to the starter, fuel injection, and interior features. That traditional Ignition Switch had what was familiar, OFF, ACC, ON, and START, also a LOCK position that locked the steering wheel and gear selector to prevent theft. Over the years, Lexus changed the RX350 to a push-button Ignition Switch that is applied with a pocket-carried fob for convenience, so the driver is not faced with juggling keys but still has to authorize via the transponder signal. Both types of styles are applied for the same purpose, but the button system involves a lower number of moving parts, so less wear that once caused jammed lock cylinders or sudden stalls when internal contacts failed. No matter what style of Ignition Switch, it is still the gateway that controls engine cranking, all component operation, and anti-theft validation in every RX350 using modern Lexus electronics.

Should you need to purchase new auto parts for your vehicle, we strongly suggest you consider the genuine Lexus RX350 Ignition Switch available on LexusPartsNow.com. Our OEM Lexus RX350 Ignition Switch come with the reassurance of the manufacturer's warranty, a hassle-free return policy, and speedy delivery service, all at affordable prices online.
