So.... some how I managed to break my key for the SL yesterday, luckily I was in the local petrol station, so my wife got a lift home to retrieve the spare key and all was sorted.
A new one from MB re programmed etc is £333.
I've tried one of the services who say they can do it cheaper but they can't for a 2015 model.
Any one had any luck getting them cheaper with my model of car?
 
How broken is it… Can the inners be swapped in to a used key?
 
The square end that fits into the car dash has snapped cleanly off, it actually clips back together but still won't work so I'm a little baffled as to why.

I’m not sure if the plastic end block contains a working part to the key, hopefully somebody else can fill in the knowledge gap.

I cant see anything in the plastic end at all; all the gubbins is sticking out of the rest of the key which is why I'm confused it wont work!

Dropping it may have dislodged something, can you compare the 2 without breaking the working one?

Looks exactly the same..... anyway have done a little more digging.

I was told initially by more than one "specialist" car key replacement company and main dealer that a 2015 SL400 (even giving the chassis number) had the new security system which means I have to use the main dealer for the replacement key; because I don't need the slide out manual key (I still have it) its £333.00 at the main dealers. If I hadn't about another £100 I believe.

However not to be defeated I continued my research....

I spoke to someone who actually knew what they were talking about local to me, they asked me to look at the key and check if there was a 7 or 8 digit code stamped on the key.

There was an 8 digit number which means although in 2015 they changed the system my car still has the old security system!

As I already have the car booked in for service once I'm back from hols in a couple of weeks I've arranged for the key guy to visit the MB specialist at the same time and sort the key out.

Result.... to be fair I don't know how much as yet until he sees how much needs doing but even a full key replacement is only £180.
 
Good result!
