• If the key enters the lock and the whole of the lock spins around when turned anti clockwise, try pressing the red plastic cover hard down on to the face of the lock. If this proves unsuccessful then try holding the lock with your thumb or finger, however to do this it may be necessary to remove the red plastic cover. If this resolves the problem then check the red plastic cap as there may be a split in it and it needs to be replaced. 
  • If the key enters the lock and turns but will not lock in place, then the problem will lie in the assembly or fitment of the clamp. Firstly check that the arms have been assembled in the correct order and that the disc spring is in the correct orientation. Refer to the white label on the rear of the red hood. Failing this, then ensure that the central locking nut is positioned in the centre of the wheel.

  • If the key enters the lock but will not turn. Check that it is the correct key for the product and that there is no damage to the profile at the end of the key or that it is not worn. Also check for debris in the tubular part of the key.

If everything is ok with the key then try holding the head of the lock bar to stop it from turning whilst attempting to turn the key a quarter turn anti clockwise. 

If you are still unable to turn the key, then take a close look at the 10 pins that are located radially within the lock. Each one of these should be at the same height as the other, and should move up and down freely. To check this, use a pin to push each pin down individually in order to check the movement if any of them are found to be at fault, we recommend the use of WD40 to flood the lock to remove any dirt or grit. If compressed air is available then blow the lock out ensuring that the correct protective equipment is used. Further lubricate the lock again with WD40 and push the key in and out repeatedly to lubricate the pins. It may be necessary to repeat this process until the pin is released.

  • If it is not possible to insert the key into the lock. Check that the inner and outer notch of the lock are in line and that it is possible to insert the key into the lock. If not and the notches are out of alignment, file the outer nib off a key and insert it to realign the two notches. If this was the cause of the problem then we recommend that the ball bearings and the area around them are cleaned with a wire brush and lubricated with WD40, we also recommend that the modified key is replaced.
