Match the original AG board, FCC ID, frequency, four-button hatch layout, case shape and blade profile. Model year, trim or engine alone does not establish key compatibility. Factory push-button-start/proximity systems only; other board letters, sedan trunk-button variants and conventional-ignition keys are not confirmed. Applications outside the listed ranges are not confirmed by the reviewed records.

Programming and emergency blades

Both remotes require professional programming and blade cutting by a qualified automotive locksmith or dealership. Confirm installer support before purchase. These are unbranded aftermarket remotes, not genuine Lexus keys, and do not add factory features. A screwdriver shown in the opening-detail photograph is not included.
