Do these covers work with the factory key?

Yes. The keyhole is pre-cut and aligned for your factory key to enter and operate the lock cylinder without any obstruction or modification needed.

Will these bolt straight onto my door handles?

They're designed to use factory mounting points, so no drilling is required. Test-fit before final fastening to confirm alignment with your specific handles.

Do I need to paint these before installing?

Not unless you want a custom color. They ship ready to bolt on and will match the factory finish for a stock appearance. If you prefer to paint them, prep and install as you would any hard panel accessory.
