Saw these today on a pole at the corner of E. Victoria St. and Carmelita Ave. It’s a little odd that a set of keys was hanging from a pole. I assume that they were on the ground and a nice person found them and hung them up so the person that lost them might find them. 3 of the keys belong to an older GM vehicle, from back in the day when there was one key for the door and another for the ignition. The 4th key is to a kryptonite lock. I left them on the pole, if they are yours you can collect them from it.
