Will these covers fit over my factory door handles without any trimming?

Yes. These mount at factory points on both doors — no trimming or modification needed. They're engineered to slip right over the existing handles.

Do I need to remove the door panels to install these?

No. Installation happens from the outside. You're bolting covers directly to the factory handle mounting points. Standard hand tools and basic fasteners are all you need.

What's the best way to keep the chrome finish looking clean?

Wipe down with a soft cloth and mild soap and water regularly. Chrome is durable and resists oxidation, but keeping it dry and clean extends the shine. Avoid harsh chemicals or abrasive scrubbing.
