Just bought a 2014 C300 which does not have the push button start like my previous GLK had. Is it possible to purchase the button to gain this ability?

xsever

It's not as easy as purchasing the button. If the car did not come from the factory with this feature, it's very difficult to retrofit it. If you provide the VIN of the car, I can decode it and double check whether it has the feature from the factory of not. The feature's code is 889.

Darn it, it wasn't a big deal to me at purchase time because I thought I could do this. The VIN is WDDGF8AB1ER320478 .Thank you for looking it up for me!

I decoded the VIN and no it doesn't have it. Remember, keyless go means the car will come with the special door handles which open/close based on your touch or finger input hence why it's not that easy of a retrofit.

xserver - I was hoping you could help me, same question but for a 2013 c250. Vin WDDGF4HBXDR260696 . I have the door handles that lock/unlock as you mentioned. If I can add this, do you know what part # I would need to order?

Thanks in advance from a newbie.

Thank you for the check. My previous GLK had the doors and ignition button both I'm ok with not having the handles if there is a way to just add the start button? Thank you again

Your car DOES have keyless go so I think you have to go to the dealership and order it because the key and the button must be programmed to the car's VIN.

Quick update - Since I had the keyless go, I bought the start/stop button. I installed (about 10 seconds) and it and works with no issues, nothing needed to be programmed or matched to the VIN. Could not have been easier.

xsever

That's awesome! Thank you for correcting my information. Enjoy!

If you don't mind, what did you pay for the button and did you buy through dealership? Mine has keyless go, as well, but did not have the button when bought. I believe a dealership quote was about $150 new but not sure if it would work just as well if I bought through Ebay or wrecking yard.

My C250 - CPO - coupe came from MB of El Dorado Hills. I'm unsure of costs for the "button" (but I have nothing but respect for the dealership).

all the best,

Mine was a CPO as well through MB Rocklin. But also being a LEASE return that came with keyless go and sold to me as a CPO without it. Von Housen Autos is great all around but the Sacramento dealership seems to stock all the good stuff.

xsever

If I bought and paid for a CPO, they better provide the keyless insert for free!

UPDATE:

MB Rocklin quoted me $62 ($58+4 tax) for keyless go button which they had in stock, which basically plugs into the slot where the key goes.

I paid $48.50 plus tax for the start/stop button. Purchased directly through the dealership.

Could someone check my VIN as well for keyless go? Not sure what to look for on the door handle. 2014 C250 sport WDDGF4HB8ER312201

xsever

You don't have keyless-go.

MY 2012 SL550 vin number is WDBSK7BA5CF168508 and has keyless start with no button in key insert. Is mine capable of START/STOP button insert?

xsever

Yes it is capable because it came from the factory with 889 - KEYLESS - GO. I double checked by decoding your VIN.

I purchased mine on Ebay for $20 (new) - never had an issue.
