What would be the price for a new set of keas for a 2014, 350 Mercedes Benz Car with 1800 miles on the speedometer, in four years.

You can use Google on the web and find an after market solution for @$250...And I saw a van at the West Herr Jeep dealership the other day that had replacement keys on the side, might want to search the web for them as well.

Do you have at least one key or are you looking for a whole new set? If you have one and need an extra, we can order one pre-programmed and it is about $500. If you need both then the car must come to the dealership and be reprogrammed.

You're looking at $500 - $800 most likely. You need to make an appointment with service and they will provide pricing for key + programming.
