I'm in the same position as Michael, one way street, double yellows, work alone. I have a keycrypt and the majority of keys that are coming now are ID46 chipped.I can see flaws in your suggestion Lee Firstly the customer isn't going to be very happy at having to do half the job themselves, secondly a little old lady with a Nissan Micra isn't going to have a clue what you would be asking her to do.
