First check that it's actually the clutch that's failed. There will be a 2 pin connector on the clutch. One is ground, the other is 12V supply. Make a temporary connecton direct to the battery an see if it engages. If so, the electronics under the dash may be faulty, or the engagement switch could be duff.
If the clutch IS faulty, replacement id the only option.
