I just bought a new honda fit with manual door locks. the paint is already chipped around where you insert the key. It is a very weird handle and lock. the handle has a little hole in it, and you put the key through the hole and the lock is underneath the door handle. the dealer will touch up the paint, but is there anything I can put around that tiny hole to prevent more chipping? They said they could not apply that plastic film around it.
If you’re really concerned about it, have a keyless entry system installed. They don’t cost all that much, and then you don’t have to use the key to get in the car.
I don’t think one can get a keyless entry system with a manual door lock.
