Good grief. Were they all driving unmarked cars or did he fail to notice what emblem was on the door? I am not surprised about the keys fitting. Others mentioned that Ford will deliver you a fleet that all use the same key. IIRC, the older cop cars had different door cylinders that used the same key as the ignition, not like civilian CVs. The offset of the two rows of teeth is normally different between the door/trunk and the ignition key so they don't even fit in each other's cylinders.
