Default What happens if you ever lose a "chipped" key for your car?

But don't you need at least one active key to program it from?


Depends on the vehicle I would think. If you or the locksmith have the
"real" factory scan/diag unit you can normally program new keys without
any current keys.


Just wanted to add, on many vehicles, the _key_ is not programmable.
rather, the scan tool or key replacment procedure programs the
vehicle ECM (computer) to recognize the key. What's more, certain
make/models have ECM with a limit on the number of keys they will recognize,
and no way to "free" a key code no longer used; IOW, once you've
programmed the vehicle for new keys 10 times (typically, might be more/less)
that particular vehicle will not be able to have any more new keys added
without a new ECM too. Good luck with that.


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.
