Hello! I just bought a 2012 S550 a few days ago. When I ran the VIN in a decoder it said I have option 889 for Keyless-GO. However, the car did not come with the button. Can I just buy any MB Keyless-GO button from eBay or does it have to be brand new from the dealer? Also, would it require any type of programming? Thanks!

most likely, you'll just need missing button...

This is deja vu. I think there were two similar questions this week???

Just buy the button from the MB dealer or from Ebay for $35 or so...stick it in the ignition and you'll be ready to go.

It seems most of the Ebay listings mention it's for a 2014....will they work for a 2013?

I tested the button from a 2014 ML350 in my 2007 S550 and it worked just fine

If you look at the part number and it starts with a 221 you should be fine. I think the same button was used across multiple platforms as xpl0sive seems to have confirmed.

Thanks fellas. I kind of thought it would work, however, the fact the Ebay postings didn't mention years before 2014, had me a little unsettled.

Mikhail ... did you get this to work for you? I bought a button on ebay that does not work even though it came in official OEM packing?

thanks

are u sure you have keyless go? also, make sure your car detects your key... may need new batteries or antennas
