This video makes me smile because of an old key I have. It is a copy of a friend’s key from my freshman year at Ohio State in 1974. No telling how many generations old this key may be. Let’s just say all the cuts are VERY rounded off. The key is an Otis Elevator service key from that time. It worked in every Otis elevator I encountered back then. I lived atop an 11 story dorm and loved having express service by running on manual! I worked in a restaurant on top of a 40 story downtown restaurant. We used the key in the service elevator to get to the roof!

No Multiplicity movie clips was a missed opportunity

Yes, completely out of tolerance by the time you got to the eighth key that’s something that all General customers should know so it’s something whenever they ask me to duplicate keys. I always ask how well that key works that they currently have because that will make a difference on whether the duplicate key would work correctly or not. 😊

Plain to see with multi-generation photo copies, too: more visual ‘noise’.

That's why copy from bidding numbers is a better way to do it.

Copies are going to be imperfect, especially when using older machines like that one. Obviously, you will eventually get one that doesn't work. What is more interesting is why a copy of an older worn original has problems?
