accumulated over years, some i got from other operators, some from the boss, some from the dealer.
the best way is probly to go the the dealer, ask a parts guy for a key for the equipment your running. all cat keys are the same, john deer has one for excavstor and one for loader/dozer/grader/backhoe, hitachi excavator key (north amercian models) is the same as john deere excavator, komatsu is all one key, case loader is the same as ingersol rand and bobcat, etc....
Someone told me the other day that a local locksmith refered him to a particular dealer in town, saying that dealer offered a set of keys that included all ( i assume most of local commonly used ) equipment keys. Maybe inqure about that when talking to your dealer(s)
...... beware of an operator thst doesnt know what all his keys are for, he probly just stole them from a lowbed driver to pretend he ran lots of different equipment. ?.
