Common failures in high-security locks



These are the most common failures that may appear in high-security locks:

  • The key doesn’t go into the hole: This may happen due to a damaged key or dirt in the cylinder. To fix this, you need to file the key correctly to avoid rough edges and carefully clean the cylinder.

  • The bolt doesn’t work: Misalignment of the bolt due to the regular use of the door. This can be fixed by tightening the bolts/strike of the door or lubricating the bolt with graphite spray.

  • The bolt gets jammed: This may happen because the door has moved for some reason. This can be fixed by moving the bolt to a new position or adjusting/replacing the hinges of the door to restore it to its original position.

  • Difficulty turning the key: This may be due to poor lubrication. To fix this, apply graphite spray, and if this doesn’t work you will need to change the lock.
