I have been trying to find the key for my original Mazda locking wheel nuts and starting to suspect I lost it some weeks ago when sorting out my rear brakes. I found the bag they came in originally (provided by the previous owner) and it has the parts number MLE 8100-77-691 printed on it, is that a unique number for this type of nut pattern or a generic number for locking wheel nuts of various key pattern?
I found a seller on Gumtree that has a set of wheel nuts with the same number, but not sure if that means the key with that set will definitely work for mine or if I need another number to find the right match?
The code for my Mazda locking wheelnuts key is an 8 digit number with no letters or spaces. The bag it came in has an âMLEâ number, different to yours (Different model of car/year ) so my guess is that itâs just a parts number.Â
PS: In the wallet with the ownerâs handbook Iâve got a leaflet about the locking wheelnuts with the code number on it.
Not Gospel - but AFAIK most dealers stock Mcgard wheel nuts and locknuts, but your code will be difficult to trace. If that number is just a part number (as opposed to a code) then you may have a problem. FWIW, Demon Tweeks sell Mcgardâs too, though again, they may not be able to help with a code, except unless you show them the nut pattern. Mcgardâs main European office is in Germany, so you could possibly send a close up photo of the nut head to them and possibly they can help. Iâve always found them very helpful.
As Gerry says, if you donât have the code you have a problem. You need either the key or the code to order a replacement. I donât think they can do it by a photograph as the differences are very subtle. Always worth a try, but unlikely. I think you may have the force those off and replace them if they key doesnât turn up. But Iâd be interested to hear if you do find a solution.
Just thought - IIRC the McGard locking nuts and lock key came with a small slip of cardboard with the code number on it, the instructions said âKeep it safeâ - Did you?
 EMG have a master set of keys and can remove your current lockers. You could then buy a new key or (easier) a new set of locking nuts and a key, or just fit standard nuts. Alternativel, if you post a photo of the face of the locking nuts you have I may be able to help you out.
I bought a used Mk4 with the same problem. The locking wheel nut key was missing but I too had the original wallet with MLE 8100-77-691 on it. This was not the key code. Fortunately for me, inside the envelope was a leaflet with the 8 digit key code printed on it, and this was the number I needed. I took it to the Mazda dealer who ordered a replacement key for me. Ok, so it was a slightly more expensive way of doing it but worth it for the grief it saved.
Mazda dealers (and probably the local tyre depots) have tools to remove locking nuts when no key is available, but it wrecks the nut in the process. However, without the key code this is probably the next alternative.
The locking nuts are Magard, but I would suggest going through Mazda to resolve.
When I bought my NisekoâŚjust over 1 Year and 10,500 mls agoâŚI found a piece of scrumpled paper in the orange dealer bag, along with the key for the locking wheel nuts.
This turned out to be the wheel nut code. I immediately copied it onto the inside cover of the handbook and ordered spare key from Mc-guard.
From memory this was about ÂŁ16:00 including postage. One key lurks in my small toolkit in the boot and the other in the dropdown compartment between the seats.
Thanks for all comments!
I will try to get a photo of the lock nuts uploaded later today or tomorrow, also going to have a dig around all old papers that came with the car. The previous owners started a good tradition of keeping basically everything so with a bit of luck I shall find a code somewhere. Also going to have a look around the garage and everywhere else at home to see if I managed to place the damn key in a new âcleverâ place.
I had to scrap a set on my Mk2 a few months ago when I âlostâ the key. Fortunately only a ÂŁ6.99 ebay set. Ordered some more, then found the key a few days later in one of my clever places, my âman tinâ in the kitchen drawer.
Anyway - the leaflet with the key for the ND came with a removable code sticker on it and a diagram suggesting the sticker be transferred to the inside of the glove box lid. Thatâs not going to happen because the ND has no glove box, but you might want to check yours.
It would not have gone far. It could have rolled away from where you were working or been left on the socket you used to tighten the nut. Search the boot and your tool kit again .There are people who can remove the lock nuts if the worst comes to the worst. I always remove these locks and replace with ordinary nuts. More bother than they are worth
Hereâs an image of the wheel nut pattern. I will have a serious look around for the missing key, it cant have gone that far. Did the work on a neighbours driveway so it will be somewhere in the general area, but probably will order a new key regardless if the pattern can be identified. Makes sense to have a duplicate!
Took a deep dig in all paperwork yesterday and managed to find the original codes for the key! Ordered a replacement key from McGuard so I think I am in the clear now, 16 Euros including delivery from Germany wasnât too bad.
