Do these require any fasteners or adhesive to install?

Mounting method not specified — test-fit before committing to fasteners or adhesive. Some buyers use existing factory holes; others may need to source small clips. Confirm fit on your truck before deciding on attachment type.

Will these work if I still have factory door locks with keys?

These are designed for doors without a keyhole, so they won't fit over an existing key cylinder. They're built for trucks that use keypad entry, push-button, or remote unlock only.

Can I paint these to match my truck's color?

Yes, the hard panel surface accepts paint. Light sanding and a quality automotive primer followed by your truck's color will work. No specific primer or paint products are required—use what matches your existing finish.
