Laminate Floor Repair Removal vs Putty

We have recently moved into a new home that has tongue and groove hardwood laminate flooring all through the main floor. When moving in something was dropped on the floor and severely chipped the floor. We were told you can purchase repair kits from the manufacturer, but I am affraid that since it is in a high traffic area the kit will not last and be noticable. Someone suggested removing the damaged plank and replacing it.

What is the best way to fix this problem? If replacing the plank is the best way, do you have to remove all the planks to get to the damaged one or can you cut the damaged one out without affecting the integrity of the "floating floor" design. Please help.

Thanks,
Nein

 

if the floor is a non-snap floor, then you can remove the one board. If it's snap, removal of the field is preferred.
