Dealer wants about $530 for a new key...there HAS to be an alternative...
I'm in Indianapolis...so if I need one programmed, etc.. I am not sure what route I'd have to go.
I just can't stomach paying half a grand for a single key to this vehicle. Any recommendations?
As M-B owners we expect high security so that we can ... as an example ... turn over our key to a parking lot attendant without concern that our key will be duplicated while we are at lunch. Not that it can't be ... or won't be ... but not easily. Keeping control of the machines for making M-B keys is ... well, it is key to doing this ... pardon the pun!
So ... where is the other key? If your vehicle was CPO by M-B you MAY have a case to have the dealership comp you a second key. It's worth a try, but if it was a private sale ... well, @fabbrisd has already described what you must do ... sorry!

So my understanding is with a 2nd key ordered...they would need the original key as well to pair them up, yes? We have a key. We went 8 years never losing our two ML350 keys...but still makes us nervous to only have 1.

I have had to chase her down a few times though when i dropped her at the door of a restaurant and the light starts flashing NO KEY!!!!
I was driving, had my key in my pocket, my wife had left her purse at home as she had no need for it. I left her in the car while idling to go into a store, but she had to chase after me for my key to keep the car from beeping!
Rule #1 — Both owners always have their keys on their person while driving together.
Rule #2 — Refer to Rule #1

My fear of using the ebay black fob + cheap locksmith approach is security. Dude can probably print your key when ever and try to come find your car...




I believe I have done that in the past for my other Mercedes' or when I needed a spare key for remote start.
It's been a while - but I had to have all keys reprogrammed, but it saved me a little money - but added a lot of time/research. I think the dealer programming was 1-2 hours so wasn't much savings.
This isn’t like your house key ... any hardware store can cut a new house key, which means anyone can duplicate your house key if they can get it to a hardware store before you notice it is missing!
I don’t want anyone other than M-B to be able to do this and if they need to do it I damn sure don’t want to surrender a key to make another key. Could a rogue M-B employee look up your VIN, create a new key from that VIN and steal your vehicle off the street? I guess so, but M-B “owns the problem” if that happened.
