The problem comes when you not only have to replace the keys (which typically sell for about $120-$240 these days) but the lock cylinders in the door(s), the glovebox, the trunk, and the steering column. The latter of which is typically held in place by a single-use bolt that has to be drilled out to remove. The module that responds to the keyless entry signals can easily be reprogrammed, often without tools. However, sometimes they can only hold so many codes before they get "full" and have to be replaced. Honda is 10, I think. Ford is probably similar. So don't lose your keys too often.
