I'm almost sure that there is a way to mend a broken key.

On the one side, Mard and CSK know each other - They've met before - Someone else has once summoned CSK - One of the golden keys was broken for at least once.

On the other side, all golden keys are mint before Lucy breaks the key of Aquarius.

So... Obviously.
