How to Replace the Ignition Key on a Lexus RX300

A replacement key is needed, if the original set has been stolen, lost or damaged. New keys must be cut and programmed by an authorized Lexus dealership or a locksmith who has the correct tools to program the key. The key contains a transponder, which is a chip that is used to communicate with the built-in computer system of your vehicle. The locksmith must have knowledge of the transponder to properly program the key.
