How much does it cost for a key for a Mercedes slk 230?

$ 35-45

Had to get a key made myself , it is only made through an authorized Mercedes dealer, they will need the Mercedes vin number, and they need to see your drivers license and registration to makes sure it is you.

They keys are laxer cut, the dealership normally has to ordered it, vin number is all they will need to make a copy key, takes about 4 days
