If you have TESA locks on your doors at home, opening them might turn into a headache if you lose your keys. However, if you have the right tools available at home, opening a TESA lock is fairly simple and you can master it within a little time. The important thing to learn about opening a TESA lock is familiarising yourself with the structure of the lock from the inside so that logic can guide you how to pick the lock successfully.

  1. 1

    Examine the TESA lock very closely to determine the type.

  2. 2

    Get the appropriate sized tension wrench and a pick that can easily slide into the TESA lock.

  3. 3

    Slide the tension wrench inside the TESA lock and turn it over clockwise. If the cylinder inside the lock gives a little that means that is the right direction. If the surface of the cylinder feels stiffer, then try turning it counterclockwise.

  4. 4

    Hold the tension wrench in position while getting the pick. Rest your hands on the table while holding the TESA lock to maintain a firm grip.

  5. 5

    Insert the pick inside the TESA Lock and get a feel of the inside structure of the lock. Press upon the individual pins inside the TESA lock starting from the one near the entrance of the lock.

  6. 6

    Continue pressing the pins with the pick and at the same time increase pressure from the tension wrench.

  7. 7

    Feel the pins giving way and being pushed upward. Continue pushing the pick onto the pins so that they completely give way.

  8. 8

    Push all the pins upward and turn the tension wrench in the right direction. You might have to turn it a couple of times in order for the TESA lock to open.

Tips and warnings

  • The pins continue to press down when you push them up with the pin; keep the pressure constant but gentle.
  • If the pins are stubborn and do not move, ease the pressure from the tension wrench and then increase pressure again.
  • Don't try to struggle with the inside of the lock if it's not turning when you insert the tension wrench; try to turn it in the other direction.
