Will this handle work with my existing door lock cylinder?

The keyhole is integrated into the handle design. Check that your lock cylinder orientation matches before installing — if it's a straight swap from the original part, you're good.

What hardware do I need to install this?

The handle attaches at factory mounting points. Fasteners are not confirmed as included — have basic hand tools and hardware on hand in case you need to source clips or screws separately.

Does this need to be painted?

This comes as a replacement part ready to install. If your door panel is a different color or finish, test-fit first to confirm match before committing to installation.
