This is what the dealer will do;

Disable the missing key in the EWS - stops the lost key from starting engine.
They will want the two remaining keys to make sure that they disable the correct one.

If the key you lost had a remote opening etc then they would also;

Do the key sync procedure with the remaining remote keys - stops the missing key from remote operation (if you search the forums you will find how to do this yourself).
