Will this fit my Sedona if it still has the key lock on the driver side?

This is a keyhole-free handle designed for the passenger side. Your driver door will retain its factory lock mechanism. They work together—no conflict.

Do I need any hardware to install this, or does it bolt straight on?

Mounting method not specified—test-fit before committing to adhesive or fasteners. Your door panel may require small clips or existing fastener points; check fit first.

Can I paint this to match my door color, or does it come pre-finished?

Finish condition not specified in the listing. If bare or primer-ready, light sanding and a color-matched topcoat will blend it. If already painted, confirm the shade matches your Sedona before install.
