Ignition Key Number Location

<< < (3/3)

If its like most of the older generation vehicular ignition key arrangements you need ideally remove the ignition switch, insert the correct key initially. Find the detent plunger on the switch casing insert a thin rod or a straightened paper clip. This should then enable the key to come out of the lock with the barrel attached. Some very sneaky ignition locks have the detent plunger hidden by a thin film of alloy casting that needs drilling out first.

Once the barrel is out you will see that the brass levers are all flush enabling it to turn in the switch. Remove the correct key & insert the one you want to use instead. With the wrong key inserted the brass levers/plates will protrude so it will not turn the lock - you file these flat to adapt it. Depending on how different your keys are might result in almost any key fitting the switch. This can be avoided on some locks by swapping the levers around - it can be a bit of a nightmare though as the small brass springs can all pop out - depends on how the levers are retained.

THis has worked for me on old car ignition  switches - I'm thinking bikes are not that different.

Unfortunately, I can't get a key - because there's no number on the switch. I was hoping that the steering lock/seat lock key (which had visible same numbers) would fit, but no such luck

Ah I thought you were just trying to get one key to fit all - methinks you will need to buy a replacement switch.
