Dealer only. I just paid $700 for a new fob for my W221. Cough it up.

.... less for more!

a spare key is random cost of ownership. This system feeds on the needs it creates.

If you think a key is expensive, compare with a single $5000 headlight unit... excluding diagnostic and labor charges.

the nearest location (Bakersfield, CA) is a minimum 8 hour round trip for me, if you miss traffic at both ends. and that is one of only two shops west of the Rockies.

'14 and onwards W212s are FBS4 and AFAIK nobody other than the dealer can program new FBS4 keys.

Any shops that claim to program Mercedes keys will be able to do so for older models that use FBS3.

I'm stuck in the same boat, only have the one key and my dealer wants upwards of $1000 for a duplicate.

Holy crap, those prices are wild. I got a new one for around $350 a year or two ago. I did have to call a few dealerships; the one closest to me always wants double what the others are asking.

I believe regural fob retails about $200 and doesn't require programming, when keyless go is about $300 + 1 hr for programming. I paid $550 out the door for keyless go couple years ago.
There are aftermarket guys who can make the fobs, but usually they require ignition module removal for the job and their key will be clone of existing key.
When dealer does the programming, they can delete all lost keys from vehicle memory, what is safety feature and new key is programmed on separate rack.
