Will these covers work with my factory door lock cylinders and handles?

These are replacement covers that mount at your factory attachment points. They're designed to integrate with your existing door assembly — no removal of locks or handles required.

Do I need to paint these before installing?

That depends on your finish preference. If you want them color-matched to your car, paint before installation. If you're keeping them as-is, test-fit first to ensure proper alignment before final fastening.

What fasteners do I need to install these?

Mounting hardware is not included with this set. You'll need basic hand tools and fasteners appropriate for your door assembly — grab hardware from your local shop or verify bolt size against your factory attachment points before ordering.
