2021 Smart Keyless Entry Remote Fob

Important Notice: The 2021 BMW Z4 does not support onboard programming. Smart key remotes must be programmed using specialized diagnostic tools by a certified technician or authorized dealer.

• Step 1: Determine whether you’re replacing a lost remote or adding an additional one. All remotes should be programmed together to ensure system compatibility.
• Step 2: Schedule an appointment with a qualified technician or authorized dealer who has access to BMW-compatible diagnostic equipment.
• Step 3: Bring all existing remotes with you. Any key fob not present during programming may be erased from the system and rendered inactive.
• Step 4: If the vehicle is operational, transporting it to the service provider may help reduce overall service costs compared to mobile programming.
• Step 5: If no functioning remote is available, be ready to present valid proof of ownership—such as a vehicle title or registration—before programming can begin.
• Step 6: The technician will connect professional diagnostic equipment to the vehicle’s onboard system to initiate the key fob programming process.
• Step 7: The new remote will be securely registered with the vehicle’s electronic system, activating locking, unlocking, and ignition capabilities.
• Step 8: Once programming is complete, the technician will test the key fob to confirm proper operation of keyless entry and engine start functions.
• Step 9: Personally verify that all smart key features—including trunk access, panic alarm, and proximity entry—are working as expected.
• Step 10: If more than one remote is being programmed, each must be added within the same session—usually within 30 seconds—to ensure full synchronization.
