I took my car to a garage to replace two rear tires and they called and said they could not locate the lock nut key? It looks as though I have everything original from when the car was new (2014 GLK350 4Matic. Where would that lug nut removal "key" be with all these items?

Second, is it possible to put a full regular tire and rim already inflated where that spare is currently located? It certainly would make things easier than having to inflate the spare too.

My lug key came in a rectangular plastic box that was stuffed in with the spare. It holds the lug key and the normal bolts that the locking ones replaced. It has Mercedes ordering info on the cover. Most dealers have a universal set of keys that will work with any tire locks. They can use this to remove your locking lugs if you cannot find the originals. You may have to order an entire new set of locking bolts and key. I haven't had any luck with MB ordering just the key or even a replacement bolt.

There isn't room for a normal size wheel and tire in the spare compartment.

Yes, the nut key would not be original and would have to provided separately .
No, you can't fit full wheel into where collapsible spare is.
Also, collapsible spare sucks. I was never able to fill it with electric pump. You need powerful compressed air pump to give it enough initial pressure to seal, otherwise air just escapes. I thought I had defective spare at first time until MB roadside told me the trick. At least MB roadside assistance is for life if you ever need it.

If your lug nits look like this - fits standard socket - no special key needed - please report back
