When purchasing a new Honda ignition lock, the lock housing, ECM box, anti-theft ring and lock cylinder all come as one assembly. You will need to save the black theft ring and ECM box from the old ignition lock assembly that came off of your vehicle. If you swap these parts out for new ones, the new keys which came with the new lock assembly, will not program to the vehicles computer. Remember, you can always count on an Automotive Locksmith to do the job for you, instead of your mechanic. We can also program the new keys which come with the ignition lock assembly, to your vehicle's computer.
