wheel lock problem

twm · 02-17-2006, 06:47 PM

I have a real problem!!! The 94 964 just purchased has oem wheel locks for which the previous owner has no idea where the key is. He is lucky he never had a flat or any reason why the wheels needed to be removed since the new tires were put on 3 yrs ago. He had said the key was in the car and I drove the car 1900 miles from LA to Missouri only to discover the key was not in the car!!!! Lucky for me! I have now got to find a way to remove these locks...they are the type that the key engages deep inside the rim with a surrounding key...not the other type which I had on my other 911s which had a plastic disc over the end which was removed and a special key put inside to remove the cover. This one is much different. I need help from anyone whose has an idea on removal...and I am not a car jacker. I have even thought about drilling out the stud but I would also have to disassemble the hub to replace the stud....there MUST be a way to get this lock off. Please advise.

A Porsche dealer will have the key or be able to order a replacement. Some towing companies may have keys to extract the lock as well.

Thanks....not porsche dealer for 120 miles and no one locally has any key. All attempts to remove have been totally un-successful and caused some damage to the rim in the area of the lock!!! These were pristine rims...really aggravates me to have such a problem. Just goes to show you put a lock on the car do not ever remove it from the car and always have a backup since dealerships when they remove the tires at times forget to put the key back in the car.

Are these Porsche wheel locks or aftermarket? Porsche only sold three types: the "unlock with a key type" two versions of those because the key type was used with the early 17" rims and which ended with 964 and early 993.

The "special socket" type, which was used as a nut for the 993 and a bolt for the Boxster and 996 , that ended with the early Boxster.

The "special, but different, socket " type which is on the Cayenne, later Boxster and later 996 replaced it.

The key type you drill or break off. Porsche does not supply cut keys and now are replaced with the 993 type "special socket" locks.

The 993 (and late 964) and early 996/Boxster types require the Porsche "master socket set" to undo. Porsche can supply replacement sockets once you have the lock number (which is found by using the Porsche "master socket" set)

The late Boxster and Cayenne ones..don't know as never had a problem...yet.

If it is one requiring a socket..there are ways to unscrew them without damage (to the wheel), and any shop dealing with Porsches on a day to day basis can advise you.

If it's not a Porsche supplied lock, then it can still be removed, but the correct way needs to found for the particular lock.

You do not make it clear whether it needs a key (like a door key) or a socket (like a 1/2" drive one).

Regarding the dealership's "forgetting" to replace the key...the most common problem is new and current owners not knowing where the "one and only" key is, or not even having it with them when bringing the vehicle in for repair. I'm sure dealers have not replaced keys after working on cars, but the inference that the problem is always "someone else's fault" and that someone is the dealer or tire shop gets tiring.

I ahve a picture of the wheel lock on the rim. You can see the configuration needed for the surrounding key to insert into the lock. I hope this would explain the problem. This is not the one that requires the old style key which had a cap and you removed the cover. The oem wheel lock purchased was 993.361.057.00
Thanks for any help. I would be glad to send you pictures of the locks.

Porsche will supply the correct socket, you have to either take the car there or have the wheel nut so it socket number can be found. Or just use non-locking wheel nuts as it's not going to stop anyone taking them anyway.

I understand what you say...go to a porsche place...quite a number of miles away. Right now I am trying to make my own key out of a 15/16" 8 point socket with a central plug which has a central core drilled out which allows for the stud. The 8 points which this specific pattern corresponds to will have 2mm steel pegs which articulate with the grooves on the wheel lock. If this does not work then I just may have to go to the porsche dealer after the snow disappears....I have a C2. Thanks for the help.

Post a photo of you lugs, I'm sure you'll be able to get them off with a lug extractor that Sears offers. I think the kit goes for around $50.00 but will pay for for it's self on one use.

Good Luck,

Pelican sells the factory locking wheel nut set..and has a photo.
The part number is 993 361 057 00 M260.

I have ordered the same oem locking set with the hope that the key is the same. Responding to the comment about the sears kit is the construction of the locking device which offers very little to grab on to and there is only 31MM wide to work around the stud which you do not want to harm....if you need to replace the stud you have to disassemble the hub on this 964 if I am correct from the porsche manual.

Eli at Pelican Parts · 02-20-2006, 02:51 PM

I don't get what you're asking about clearance. The kit contains different size sockets (like your typical tire-star) which will drill-in clockwise as you counter your turns.

I'm not sure how to explain it better than that but if you have questions you are more than welcome to call or I'm sure a visit to your local Sears will make it more apparent.

I will have to look at it closer. I will try to show you a picture of what I'm looking at. What the picture hopefully shows is the wheel stud face on with the lock surrounding/threaded the stud with slots in the outside of the locking lug. The depth is only 5mm above the very end of the locking assembly Thanks

twm · 02-20-2006, 05:28 PM

I looked at the sears unit...it only goes out to 19mm or 3/4 inch which is too small for the 24mm lip it would have to anchor onto . A 1mm elevation is noted towards the stud but this while smaller in diameter allows too little to latch onto to un-screw this locking mechanism that is on with 90+- foot lbs torque. Sorry about the picture...not sure how to get this correct, I thought I loaded up right.
