How do I confirm fitment?

When should the ignition switch be replaced?
Replacement makes sense when diagnosis confirms the original component is worn, damaged or electrically/mechanically failed and the rest of the related system checks out.

Is this an OEM part?
This listing is for a replacement part. Brand names and OE/reference numbers are used to identify fitment unless the listing specifically states that the item is genuine OEM.
