Only for vehicles originally fitted with this exact proximity-key configuration and push-button start. Open the original remote and confirm 231451-0010 G, HYQ14FBB, frequency, original part reference, button layout and blade profile before purchase. The FCC ID or model year alone is not sufficient. Other board IDs or letter versions, long-wheelbase RX variants and conventional ignition keys are not confirmed here. This replacement does not add features the vehicle lacks.

Programming and key cutting

A qualified automotive locksmith or dealership must program the remote and cut the emergency blade. Self-programming is not supported. Confirm programming compatibility before installation. The photos of the supplied aftermarket electronics are included for comparison; original board-number guidance is a matching requirement, not a claim that the replacement board has original Toyota markings.
