Advice on blade for a spare key

[mephistophelean]

Hello

We are going to pick up a W216 CL600 later today. The car originally only had one key so we asked the trader seller to get a spare key. The remote has come but he has to pick up the blade and will then send to me.

Question: How much does a blade for the key typically ost and how much would you hold back (if at all) for the blade? The seller has been very upfront with everything about the car and I am happy to take these things on trust as the remote for me is the key issue but I want to know what the potential downside cost could be if anyone knows?

When I got a complete new key for my CL I think the metal blade was around £20 or so. I can check the invoice this evening.

Thanks for replying. We sorted it out with the seller.
