Will this mount using factory bolts, or do I need new hardware?

Factory mounting points are preserved—use your existing bolts if they're in good condition. If originals are corroded or missing, standard door handle bolts from your local hardware store will work.

Does the keyhole function with my existing key, or do I need to rekey it?

The handle comes as an assembly with keyhole. Test-fit it first to confirm compatibility with your ignition/lock cylinder before final installation.

Can I polish the chrome, or should I avoid certain cleaners?

Chrome plating responds well to standard automotive chrome cleaner and a soft cloth. Avoid abrasive pads that can scratch the finish.
