Encoded Ignition Key
WARNING: This page is about a different car, the 2000 Mazda B4000, 2000 Mazda B3000, and 2000 Mazda B2500. However, it is still accessible from the selected car via links, so may be relevant.
When ignition switch is in START or RUN position, PATS module initiates the encoded ignition key interrogation process. Each encoded ignition key must be programmed into PATS module before it can be used to start the vehicle. See KEY PROGRAMMING (SECURITY ACCESS PROCEDURE) under PROGRAMMING. This encoded ignition key is much larger in size than a standard key to accommodate the electronics located inside plastic cover.
