• If the key enters the lock and turns but fails to spring out then it is highly likely that part of the clamp is pinching the lock, this can be caused by loss of tyre pressure or small movements when the vehicle has settled in position. To rectify this, insert the key and turn it through 180 degrees, once in this position the lock is in the unlocked position and it should be possible to pull back on the key to release the clamp, if not then it may be necessary to push/pull the clamp to help release the lock.

  • 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 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 to re align the two notches. If this was the cause of the problem then we recommend that the modified key is replaced.
