2019 BMW 4 Series – Smart Key Remote Fob Programming Instructions

Important Notice: The 2019 BMW 4 Series does not support onboard programming for smart key remote fobs. Programming must be performed by a certified automotive technician or authorized dealership using BMW-specific diagnostic tools.

Programming Procedure:

  • Step 1: Ensure the replacement smart key remote fob is fully compatible with the 2019 BMW 4 Series. Incompatible or incorrectly matched fobs may fail to program or operate correctly.
  • Step 2: Schedule service with a certified technician or authorized BMW dealer who has the required diagnostic equipment and software for secure key fob programming.
  • Step 3: Ask if all existing remotes must be present. In many BMW systems, remotes not included in the current session may be erased and become nonfunctional.
  • Step 4: If the vehicle is operational, consider driving it to the technician’s location. This may help reduce service costs compared to mobile programming options.
  • Step 5: At the service location, the technician will connect BMW diagnostic tools to the vehicle’s onboard port to begin the programming process.
  • Step 6: The technician will initiate a secure pairing sequence that registers the new smart key fob with the vehicle’s locking, ignition, and security systems.
  • Step 7: Once programming is complete, the technician will test all remotes to ensure full functionality, including remote locking, unlocking, trunk access, and engine start (if equipped).
  • Step 8: Safely store all programmed remotes and verify they operate as expected before concluding the service appointment.
