Broken lock nut key

[Ronan33]

My locken nut key broke and it is very difficult to read the code on the box. Does anyone know what the code could possibly be for this key?

Hello and welcome

Go to Mercedes and they should be able to supply a replacement. Alternatively ask them nicely and they might removed them all for you. You can then replace them with the normal wheel bolts that should be in the little case in the boot ( where the locking wheel nut adapter lives)

Only if you have the original code from the box they came in .... if not, they'll be clueless.

It's difficult to read. If you have any idea of what it is. I searched different numbers of what I thought they could possibly be but I can't seem to find a match

OP would be better off going to ATS or a local tyre place than go to MB. ATS/similar, will likely have a box of these ... https://www.machinemart.co.uk/p/clarke-pro406-emergency-wheel-nut-removal-tool/

When MB remove your wheels they don’t use your key... they use one of their adaptors... they have the full set.
A lot of the removal tools are too big to go into the recess. Issue I had with my W212 (when Mercedes over tightened them...)

The code is missing from my locking nut case, but I thought the code was a lot simpler ???

There is usually a peel off small sticky label on the box that they tell you to fix to the MB owners manual. Still have sticker from old and the one from the new set on my MB car manual.

When I broke mine, MB dealer came out with a big box of 26 from memory wheel lock bolt adapters found one that fitted and removed troublesome bolt.

is there a letter stamped on the hexagonal bit at the other end of the key, possibly on one of the flats

If you can match the pattern visually you can usually find them on eBay. Or even buy a whole master set!

Go to the dealer they have them in shelf in the workshop and will take them off for you and give you the number to buy a new one fron the parts dept.
I have had both these scenarios in the past

When I lost wheel nut key, just went into MB parts dept and they have a ‘master’ set.
find which one fits, and they had it in stock - easy as pie. £30.

F1 autos massively overtightened mine and it snapped, had to get a specialist to weld and remove damaging cosmetically one of the wheels... wasn't happy!

MB will have a master set and the parts dept can order a new key for £10 if they aren't hammered on tight

Merc dealer parts dept will be able to try from their master set and sell you a replacement. This may only be the start of the saga though.
I had a similar problem and even with the new key couldn't get the locking nuts off. Eventually a local small garage ground down the outside of an ordinary socket to fit the wheel recess, hammered it on and then needed a 3 foot bar to undo them. I think as well as overtightening a bit of corrosion occurs between the wheel and the bolt.
Once you get them off leave them off or if you do put them back put some lubricant on the head where it touches the wheel.

I had similar issue, I took my nut to mercedes and they had all the different ones. You match it up with you're one (trying it with your bolt) and you're good to go

We have drilled the bolts in the past, very time consuming but sometimes the only way.

https://www.lockingwheelnutkeys.co.uk/ are very good, and we have used them in the past, they can often match a locking wheel nut by the picture.

We know all about broken locking bolt keys.........All the best equipment was useless as was the tyre company with their B all and end all state of the art remover that snapped off
I had to go to and engineering firm who was able to use the Oxy/Acetylene and gas cut the bolt head off.
If you get another locking key, don't let any one other than yourself nip the locking bolt up!!
