Oiwa Garage Tech Note
"Test the switch feel before final assembly - it is far easier to sort the wiring and cylinder with the column trim off than to go back in later."
Frequently Asked Questions
How do I know the ignition switch is failing?
A key that will not turn, cranks intermittently, or lets accessories drop out in the run position points to a worn switch or cylinder. Wiggle the key while it is in run to see if the fault moves.
Can I test the switch before final assembly?
Yes - check the key turns through off, on, and start and that the electrical positions work before you refit the column trim.
Will the new keys open my doors?
No - your door locks keep the original key, so you will carry two keys unless you have the doors re-keyed to match. The two keys included here run the ignition.
Does this fit the Acty Van?
Yes - the Honda Acty Van HH3, HH4 (1996-1999) uses the same assembly. We list the van version separately so you can confirm fitment against your chassis code. Have a 1990-1996 Acty? You need the earlier switch and cylinder assembly instead. And if your key cylinder is fine and the fault is purely electrical, the main switch alone is the cheaper fix.
