Official summary

Service bulletin - all of the listed vehicles have a type 4 immobilizer system that disables the vehicle unless a programmed ignition key is used. The type 4 system is different than previous systems in that the transponder id code in the key is a rolling-type code instead of a fixed code. In this service bulletin, a programmed ignition key refers to a transponder-type key that has been cut to fit the ignition switch and whose transponder id code is recognized by the immobilizer system. If you try to start the engine without a programmed ignition key, the engine cranks, but it does not start.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
