If you’ve ever found yourself locked out of a door with no key in sight, you may have wondered if there’s a way to unlock it without calling a locksmith. While we always recommend seeking professional help, drilling a lock can be a last resort option. In this step-by-step guide, we’ll walk you through the process of unlocking a lock with a drill.

What You’ll Need

  • A drill
  • A drill bit (preferably a titanium-coated or high-speed steel bit)
  • A lubricant (WD-40 or any similar penetrating oil)
  • A flat-head screwdriver or chisel
  • A pair of safety goggles
  • A replacement lock (in case the original lock is irreparable)

Step 1: Prepare the Lock

Before you begin, ensure you have the necessary permission to drill the lock. Start by protecting the surrounding area with a cloth or tape to prevent any damage to the door or frame. Apply a small amount of lubricant to the keyhole to ease the drilling process.

Step 2: Choose the Right Drill Bit

Select a drill bit that is the appropriate size for the lock’s pin chambers. It’s essential to choose a bit that matches the size of the pins, typically around 1/8 inch to 1/4 inch. A titanium-coated or high-speed steel bit works best for both durability and efficiency.

Step 3: Start Drilling

Put on your safety goggles and position the drill bit at the center of the keyhole. Apply light pressure and start drilling slowly. Keep the drill level and try to remain as steady as possible. The goal is to drill through the pins without damaging the lock mechanism.

Step 4: Increase Speed and Apply Pressure

Once the drill bit has penetrated the pins, gradually increase the drill’s speed while still maintaining control. Apply a bit more pressure to speed up the process, but avoid excessive force that could damage the core or make the drill bit snap inside.

Step 5: Remove the Lock Cylinder

As you drill, you will feel less resistance. This signals that the pins have been successfully drilled through and the lock cylinder is now free to turn. At this point, stop drilling and gently remove the drill from the keyhole.

Step 6: Unlock the Door

Use a flat-head screwdriver or a chisel to turn the lock cylinder and unlock the door. Apply gentle pressure to avoid any damage to the internal components or the door frame.

Step 7: Replace the Lock

After successfully unlocking the door, consider replacing the drilled lock with a new one. Removing a drilled lock entirely is essential for security reasons, as it could be manipulated or bypassed by others. Install the replacement lock following the manufacturer’s instructions to ensure proper functionality.

Remember, drilling a lock should only be a last resort and seeking professional help is always recommended. Be sure to consult a locksmith before attempting this method to prevent any damage to property or harm to yourself.
