Confirm the original board number and letter G, FCC ID, frequency, four-button arrangement, case shape and blade profile before ordering. Vehicle model, trim or engine alone does not establish key compatibility. For matching factory push-button-start/proximity systems only; conventional-ignition keys and other board versions are not confirmed.

Programming and emergency blades

Both remotes require professional programming and blade cutting by a qualified automotive locksmith or dealership. Self-programming is not supported by these replacements. Confirm installer support before purchase. These are unbranded aftermarket remotes, not genuine Lexus keys, and they do not add features absent from the vehicle.
