Programming Instructions for the 2018 Acura TLX Keyless Entry Remote Fob (Smart Key)

Important: The 2018 model does not support onboard programming for smart key remote fobs. Programming must be performed by a qualified technician using specialized diagnostic equipment.

Step-by-Step Programming Instructions:

• Step 1: Ensure that the smart key remote fob you intend to program is compatible with your vehicle and has not been previously programmed to another vehicle.
• Step 2: Locate a qualified automotive technician who is experienced in programming smart key systems.
• Step 3: Confirm that the technician uses manufacturer-grade or equivalent diagnostic tools to perform the programming procedure.
• Step 4: If your vehicle is drivable, consider taking it directly to the technician’s location. This may help reduce service costs compared to requesting mobile assistance.
• Step 5: Bring all current working smart keys with you. Some systems require all keys to be present during programming to maintain synchronization.
• Step 6: The technician will connect a diagnostic device to the vehicle’s onboard port, usually located beneath the dashboard, to access the key registration system.
• Step 7: The technician will initiate the programming process using specialized software to register the new smart key with the vehicle’s system.
• Step 8: Once programming is complete, the technician will verify that the new smart key is fully functional, including locking, unlocking, and engine start features.
• Step 9: If you are programming additional smart keys, they can usually be added in the same session by repeating the procedure.
• Step 10: Before leaving, test all smart keys to ensure they operate correctly with your vehicle’s electronic systems."
