I just bought a 08 Fusion. It came with two keys. They are the new type
key in a holder that opens the doors and trunk remotely. Is there any
place to get another spare key other than the dealer? I suppose I
would need both a new key and the key holder or the car wouldn't start as
it is some kind of smart key.
If it is a smart key (and it probably is) you will need to program the new
key using 2
other keys. Look in owners manual.
Everyone with smart keys should have at least 1 in reserve (if not 2)
so if one is lost, a new one can be programmed.
Contrary to common belief, you program the ECM to accept the key &
store it's transponder pattern in it's database. The keys it's self is not
programmable & it does make good sense to have at least three keys
since it takes two to enter another in the ECM's memory. Most can have
up to eight key entries but it differs from manufacturer & firmware revision
