keychains

Hey, I just got a second-hand Vespa and have a question about keychains. When I had my old scooter, I always carried two keys on a keychain with a clip/carabiner. If I keep the same setup, will the keys hitting the painted front compartment of the vespa cause chipping or fading over time? Would it be better to keep the second key on a separate clip to avoid damaging the paint on my Vespa? (I got the Primavera 150, by the way.) Thanks!
