W212 2015 Key?

[jberks]

Hi all,
Suspect I know the answer but I’d kick myself if I didn’t ask.
The old man is delighted with his “new” Dec 2015 E220cdi SE
The only problem is, my fault, we didn’t ask if it came with 2 keys, and of course, when it arrived, it didn’t.
It was a decent price, sensible mileage, nothing bodily wrong a couple of hours with the PDR guys and a full day of paint correction from me won’t sort, and came with full dealer history ( inc over £1k spent on service and brakes in just the last few months) so we decided to go ahead anyway, figuring we’d just get an auto locksmith to sort us a new one for £150 or so.
As I’ve now come to understand, they changed the system early 2015 and the usual suspects can’t program in a key for later ones.
Hence I believe its dealer or nothing?
Before we sacrifice the piggy bank and head down to the dealership, anyone got any other suggestions?
thanks.

We have Replacement Mercedes Keys as a forum sponsor, it would be worth giving them a call first.

When I viewed/bought my current car, it only had 1 key, but the dealer said it would be supplied with 2 keys. A second remote key was supplied 2-weeks later, but it took considerabley longer for the blade part of the key to turn up.

I've spoken to a couple of people so far and the story is the same.
It appears to be dealer only, mid 2015 on.
The garage did say they were chasing the other key from the previous owner but I'm not holding my breath.
Given the state of the car and its history, it was clearly owned by someone who doesn't have the slightest whiff of petrol in their veins.
Hence, mechanically it's gone straight to the dealer, irrespective - so it comes with a pile of receipts for things there's no way I'd pay that much for.
But, whereas my cars are gleaming and kept well away from shopping trolleys (as much as is possible), this one has managed to collect 4 major shopping dings, inc one on the roof rail in it's relatively short time on this planet, and it has clearly never once been introduced to any form of polish.
Still, I'd rather have that than a gleaming one with questionable service history as all those things are relatively easily resolved. I've had a quote of £300 to PDR out the dings, I plan to spend tomorrow with my orbital polisher getting it gleaming again and I'm guessing we'll need around £300-£400 to get a key, all of which still makes it a fair price for a full MBSH motor and still a lot less than a similar main dealer presented example.
Only other concern is the EML came on. I pulled the codes and it's pointing to the NOX sensor. It came with a warranty that we upgraded so hoping that won't be a problem. Supposedly the warranty co have a deal with Halfords and if it's just swap out a sensor, they're as capable as anyone. Other than that, it runs beautifully.

Nox is update software, update datacard and new sensor, halfords may struggle.

As others have told you, that car is FBS4 so dealer only key unfortunately.

Your choice but I wouldn't go near Halfords with a Merc. Come to think of it, l wouldn't let them touch a car of any make.

Halfords aren't too bad these days. I've used then a few times and been pleasantly surprised with their knowledge and their honesty.
I figure they're a big firm so won't attempt anything they can't do as their liability for screwing up would have their legal team running to the hills. If they commit to doing something they have to be able to do it.
We chose them because the supplying garage said they had a tie in with the warranty co. Maybe, with hindsight, we should have gone to the dealer or a specialist but we are where we are.
The old man's been down today and they've diagnosed a NOX sensor (surprise surprise) and are happy to go ahead and replace it (and recode), as well as get authorisation from the warranty co which keeps things simple.
Only daft thing was the guy he spoke to "wasn't certain he should drive it in the mean time as it might do more damage".
Unless I'm mistaken, that's cobblers?
I assume, without correct NOX readings, the ECU has shut down the AdBlue injector and it's just running as a non adblue car which aside from higher emissions, has no impact on anything?

If you got the car from a MB dealer ask them to supply the replacement key.
If not then dealer only, supply your logbook, passport and they will order.
They come direct from MB programmed and not many companies out of the network do this due to security.
Thats why it will take a couple of weeks, its not an off the shelf product.

Just to close out. He's ordered a new key from the local dealer. Leeds were £50 cheaper than Harrogate so he's gone there but it's around £315 for the key and £70 to code it.
Halfords have ordered the new NOX sensor so will bang that in and reset everything in the next few days. Warranty has agreed to pay so all happy there.
It's had an 8 hour paint correction (by me so not bad for an amateur job if I say so myself) so just the 4 shopping dings to sort and we have a perfect car again ;-)

"Amusingly" - we got a letter from our insurance company last night. Apparently this car "did considerable damage to a Zafira on the 26th May."..In Salford. "Some kind passer by left the reg no of the car for the owner". Now, if this were Sheffield, or Leicester, or Brighton I might think, genuine mistake, maybe, but this car was actually in that area right up until the 24th May - when we bought it, and unfortunately for the fraudulent claimant, it's been in Yorkshire ever since. I don't believe in co-incidence, well not that much anyway.
