As you may be aware, you can get second spare key and correctly Sync, and requires costs ( approx. $200) and replica from Ford dealer,

Does appear you can clear or reset key, but without parameters or coded limiters, the Key does not work ignition, only opens door default,
So you are best to go to Ford Dealer.

If its a fusion it probably can't be started already

You need to have the "master" key to disable it. The master key is the key that was used to turn on My Key in the first place (it's disabled by default). Most of time parents who let their kids use their car will use their key (the parent's) key to turn on the Mykey. And often kids will post questions on how to disable it.

Break it in half should disable any key!
