How do you open a lock with a bobby pin/hairpins

When you are locked out of room, what can you do? Call a locksmith and pay for an expensive fee to open the door? Actually, you can use bobby pin/hairpins to open the locked door, just follow these tips below! But you can only open locks that belong to you, or locks that you have explicit permission to open.

First of all, you need to see what type of lock you have. Hairpin are suitable for most door handle locks, that is, locks in which you insert the key into the doorknob and are commonly found in indoor rooms. In general, the older and cheaper the lock, the more likely the hairpin is to open it. The method of using a hairpin to open a standard marble lock is just like the one in the special agent movie. First of all, we have to understand the working principle of these locks. Like pin and tumbler lock, they are the most common type of all locks. These pins are cut into different lengths. Only when each pin is pushed to the correct height, can the lock cylinder be made. Turn, the groove on the key is used to match the pin, so that they just rise to the point of separation from the lock cylinder, so that the lock cylinder can rotate.

The method to DIY lock picks using hairpins:

  1. Open the hairpins and bend it at a 90 degree Angle. Separate the wavy and straight ends of the hairpin so that it bends in the center and looks like an L. This hairpin will be used as a crowbar or Lock Pick Tool to unlock the door.
  2. Remove the rubber head from the bobbin straight end. Remove the round rubber tip of the straight edge of the hairpin using a knife or razor blade. This will be the end of your insistence on entering the lock to select it.
  3. Insert the flat end of the pin into the top of the lock and bend it. Insert the pin about 1 cm (0.39 in) and fold the rest of the hairpin until it is flush with the surface of the door handle. This will bend the tip at an Angle.
  4. Bend the wavy end of the hairpin into a handle for better control. Take the wavy end of the pick and bend it up 30 degrees to make the handle. This step is not necessary, but will make it easier and more comfortable for your hand to pick the lock. Once the handle is created, the pickup is complete.
  5. Bend the tip of another hairpin to make a tension rod. Take a separate barrette and bend the top 1/3 of the barrette to form a hook. Do not separate the sides of the hairpin as you would with a pick. Then, you need to bend the both sides of the hairpin in the same direction. Ok, you have make a lock pick tool successfully then and you can use the tool to unlock the door!


  1. Generally, if done properly, this method will not break the lock, but if you apply too much torque or push the marbles too hard, you can cause irreversible damage to the lock.
  2. If you encounter a marble that can’t be raised, you’re applying too much torque, which causes the holes in the lock core and housing to be too wrong, trapping the marble too tightly. At this point, you should properly relax the torque, but this may cause the previously raised marbles to fall back, if so, there is no other way to adjust the order of the marbles.
