2. How do I find the right size?

Please measure your steering wheel as shown here. We always recommend measuring
the steering wheel before any purchase since there is always the possibility that the
vehicle manufacturers may alter its size.

steering wheel diameter (A) Fitting model
350 – 385 mm DISKLOK S 390
386 – 410 mm DISKLOK M 415
411 – 435 mm DISKLOK L 440

Rim thickness (B) ≤ 40 mm

3. My Disklok does not lock easily. What can I do?

The safety cylinder is made up of several layered discs, and can only be opened by bringing the discs into the correct position with the appropriate key. The edges of the discs and the keys are very sharp and can easily get stuck to one another. Therefore, before using the lock for the first time, we advise you to have the keys polished by a specialist to remove any burrs that might be left over from production. To keep the lock smooth, we recommend our graphite powder as a preservative.

4. The key does not fit perfectly into the lock. What can I do?

In normal use (key is completely inserted into the lock) the key can be turned 3/4 of the way around in the lock. Only then can the lock be opened. The safety cylinder of DISKLOK is a “multi-disc lock”. Many successive layers have to be aligned with the key in such a way that it fits completely into the lock. It may happen that individual discs twist and interlock. This is no cause for concern. The discs can easily be re-aligned.

  1. Insert the key (without force) into the lock as far as possible.
  2. Gently turn the key from the far right to the far left and back.
  3. Repeat until all the blocked discs are re-aligned.
  4. Never use oil to make the lock work again.

5. Can the DISKLOK scratch my steering wheel?

The DISKLOK sits freely around the steering wheel, which is why the entire weight is on the top of the steering wheel. Always place the DISKLOK carefully on the steering wheel. We recommend the use of our steering wheel cover.

6. Is there any difference between the silver and the yellow DISKLOK?

No, technically there is no difference. But the yellow DISKLOK has a very much higher deterrent effect, since it is visually much more conspicuous than the silver DISKLOK.

7. Can I order replacement keys for my Disklok?

If you wish to order replacement keys, you must have registered your DISKLOK, including the key number, online in your name. If the product is not registered, we will require an original key, sent by insured post or package. Please be sure to put sufficient postage on your shipment.

8. I cannot unlock the Disklok - what should I do?

If the lock was destroyed or the key was broken, you can get help through our repair service. If your DISKLOK is locked on the steering wheel, you should have the lock opened beforehand by a key service or locksmith at your location so that you can detach your DISKLOK from the steering wheel and send it to us. Please be sure to put sufficient postage on your shipment.
