Do these covers work with factory door locks and keyless entry?

These mount over the exterior handle shell without interfering with lock cylinders or electronic components. Your existing lock and keyless system operate normally underneath.

Will I need fasteners beyond what comes in the box?

Check your kit contents before ordering additional hardware. If fasteners aren't included, you'll need corrosion-resistant bolts matched to factory handle mounting holes — a hardware store can source these by size.

Can I paint these or do they need prep work?

ABS takes paint, but surfaces should be cleaned and lightly scuffed for adhesion. If painting, use flexible plastic primers and urethane topcoats designed for automotive ABS. Factory finish is ready to install as-is.
