It might be a dumb question but.....:
Did the locksmith make your "spare keys" using your current key? Or was he able to make them without using your current key? The reason I ask is I have recently acquired 76 CB750A that came to me without a key....I cant open the tank or turn the ignition on. My 71 K1 key wont work......
Any suggestions?
The Cb750s are easy. Look between the Clocks and you will see two I think 10mm bolts maybe smaller. Undo them and you can pull the whole assembly up. On the side of the cylinder is a number, find a honda dealer or good locksmith and they can make a key.
If you want to work on the bike carefully remove the white plastic switch. You can just turn that switch and run and test the bike etc. To remove the seat for working on wiring etc, just take the cotter pins out of the hinge pins, knock out the pins, and that's it. Not high security. I think there are less than a dozen key combos anyway.
