Service bulletins for the 2004 Honda Accord

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

298 on file from NHTSA, as of 2026-10-19.

A02-0532016-12-27. Service bulletin. ELECTRICAL SYSTEM:IGNITION. 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.
