Encoded Ignition Key

WARNING: This page is about a different car, the 2001 Mazda B4000, 2001 Mazda B3000, 2001 Mazda B2500, and 2001 Mazda B2300. 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 encoded ignition key interrogation process. Each encoded ignition key must be programmed into PATS module before it can be used to start vehicle. See KEY PROGRAMMING (SECURITY ACCESS PROCEDURE)  under PROGRAMMING. This encoded ignition key is much larger in size than a standard key to accommodate electronics located inside plastic cover.
