Do these covers work over my factory door handles without removing anything?

Yes. They snap directly over the existing handles. No disassembly or tools needed.

Will the chrome finish hold up to heat and UV exposure?

ABS is durable in weather, but inspect periodically for any peeling or fading. Park in shade when possible to extend the finish.

What if the covers don't fit snugly on my handles?

Test-fit before finalizing. If gaps are present, you may need to pad the interior of the cover or confirm fitment with measurements of your factory handle width and depth.
