I'm trying to get my information straight, I just searched again but I couldn't find what I was looking for. I want to get a another key for my car since it only came with one, but I'm cringing at the $400 price tag (especially since in my searching I see people saying they paid $90-$150 for one of these keys a few years ago). I'll pay the $400 if I have too, but I just want to make 100% sure first.

It is not possible to reprogram a used Smartkey from one vehicle to another, correct? Even if I find a "new" key on eBay or something, will that work? I thought I saw someone saying to program these keys you put it in the ignition and leave it for however long, but that's only for a new key. Then I call the dealer parts department and they tell me a new key will come completely ready to go, but then the service department tells me it needs to be programmed. So which is it? (And I don't want to hear about how the dealer is trying to screw everyone). Can I save myself some money or am I just going to have to deal with it?

It's not possible to reprogram used keys....which is good....otherwise, our cars will be stolen! However, you can remove the chip on your original key and put it on the used key and make it work.

I'm not sure about new keys, but I believe it needs to be programmed before you can use it.

Mercedes can reprogramme the key if it goes back to their security centre - I have no idea if this is a cost effective option.

Just go to the dealer they don't charge much... I asked how much a new key was for my car made sure it was the chrome one... 160 dollar price tag i said ill have to get it another day. But i just want the new key..


If you just want the new key... Go on ebay buy a used key and switch the parts out inside easy as cake

I am having the same dilemma.....$160 is fine, but my dealer wants $240. And of course, they want the vehicle there and a left leg.

That's the problem! $160 would be great, my dealer (and every other dealer in the area) wants $265 + $61 to check and delete missing key plus $35 to program the new key.

I already have the new style key, I just want a second key in case something happens to the only key I have.
