Lost Remote Key Any Alternative to Stealers?

[aeu99184]

We have lost the spare remote fob key for our 2013 c max.
I have been trying to research the cheapest way to replace it but am seeing some conflicting information.

I have read that the dealers will charge me about £150 to supply, cut and program a new key.

Does anyone know roughly how much I would pay an independant locksmith for the same service? Can they even code the keys?

thanks
