Security System & Immobilizer

Acura runs Honda’s immobilizer architecture — ID46-era transponders through current Smart Entry proximity fobs.

On the RSX specifically we see: Megamos ID13. A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.
