We just bought a new Toyota Hilux. The 2 identical keys for the ignition and doors is of the old style type, similar to what I had in my 1968 air cooled VW Beetle. There's no wireless unlock feature here. My wife had a duplicate key made and began to use it regularly, and kept the 2 original keys in the bedroom drawer for safekeeping. I say we should use an original key, and keep the duplicate and other spare key in the drawer. My reasoning is that the original key will fit the ignition and door locks much better than a copy, and should keep the mechanisms longer from wear than if we used the imperfect duplicate. Am I correct here or am I overthinking this and just use the duplicate first?
