Cost of the flat (spare) key?
the problem is , that the metal key does NOT fit into the key fob .
the metal key doesn't go all the way down into the key fob, and therefore doesn't lock in place, and therefore , i can't put the key fob on the key chain.
i hope this is more clearer. so what can be the problem ???
p.s. based upon your photos of the 4 different MB key fobs , it matches my chrome key to my metal key
but they worked for a year . so maybe the combination of water getting into the fob and the wrong batteries, who knows the reason ? but i think any reputable car electronics professional should be able to fix problem.
both 2025 and 2032 r 3 volt batteries, just the 2032 is a little bit thicker and was more of a tight fit into the key fob
on how to get the older key repaired.
1. why is my NEW metal key doesn't fit into my NEW key fob ,
so what can it be due to ? and what can be done ?
2. is there anyway to fix my OLD key fob ???
as i believe rain water got into it, and its not working
how else can i make my self more clear ???
i tested both key and fob and they both open my car.
also i compared the 4 MB key fobs with their metalic key types,
and the chrome key fob matched the metalic key type too.
so it doesn't make sense. i plan to go to my local MB dealership , to get the answer

programming, if any, may only take seconds....and more often than not, could have been done by
you at home. It simply requires that the new Smartkey be inserted into the ignition and let the
codes interrogate each other and say hello. The key mechanic at the dealer performs nothing
as the metal key, along with the Smartkey, is imaged in Dallas, TX (unless something has changed)
and FedExed to the dealer.
But now you know, for future reference, that you can post on the forum and see what the collective
experiences and tips are from the members. Many of the tips here can save thousands of dollars.
You may not have had the flexibility to shop around and checking competing dealers. A competitive
price for a Smartkey replacement is more like $300, plus or minus $100.
over dealer prices.

Those are more expensive than smart key and present price is $350 + $125 for programming.
Flat (service) keys are no longer available, at least for my 2014 model.
Than I called Las Vegas dealer for total quote of $675 and they say they need to see the car to place the order, but not for picking up the key.
So not only the prices vary a lot between locations (what else is new?) but seems the programming is BS and simple price gouging.




The picture is not clear and description says about transmitter, but it is the key no doubt. This is the price I paid for chrome key over 10 years ago.
Worth emailing them what is procedure.
