On some Fords at least you get something like 8 active keys max by
default, but the dealer or someone else with the VCM/IDS laptop can set
the PCM to unlimited mode which is intended for fleet use.

That makes sense. I also realized that if you had your key off to a valet
parker for more than an hour or two that THEY could easily clone the key,
toss the car looking for an address and pick up your car a few weeks later,
easy as pie.

Only if the valet has the dealer's programmer, otherwise he would need two
keys.
