Drilling a lock is a task that is often associated with locksmiths and other professionals, but it is also something that can be done by do-it-yourselfers. However, it is important to note that this is a delicate procedure that requires precision and skill. In this article, we will guide you through the steps on how to drill out a lock, providing you with the necessary knowledge and techniques to successfully complete this task. Whether you are a homeowner looking to replace a lost key or a locksmith looking to expand their skillset, this guide will provide you with the essential information you need.
Before you begin, it is important to gather the necessary tools and materials. These include a drill, a drill bit, a hammer, a nail, a center punch, and a screwdriver. Additionally, you may want to wear safety glasses and gloves to protect yourself from any flying metal or debris. Once you have gathered your materials, you can begin the process of drilling out the lock. First, you will need to remove the screws that are holding the lock in place. Once the screws are removed, you can then use the hammer and nail to knock out the lock cylinder. This will expose the lock mechanism, which is where you will be drilling.
Next, you will need to use the center punch to create a small indentation in the center of the lock mechanism. This indentation will serve as a guide for your drill bit. Once you have created the indentation, you can then use the drill to drill a hole into the lock mechanism. Be sure to use a drill bit that is the same size as the diameter of the lock cylinder. Once you have drilled the hole, you can then use the screwdriver to remove the lock mechanism. With the lock mechanism removed, you can then install a new lock cylinder and replace the screws that were holding the lock in place. By following these steps, you can successfully drill out a lock and replace it with a new one.
Preparing for the Task
Meticulous preparation is crucial for successful lock drilling. Ensure you have the following tools and materials:
Tools:
- Drill: A handheld battery-powered drill or a drill press is suitable.
- Drill Bits: High-quality drill bits designed for metal, typically HSS (High-Speed Steel) or cobalt bits.
- Center Punch: To mark the precise drilling location.
- Hammer: To drive the center punch.
- Safety Glasses: Essential for eye protection.
Materials:
- Lubricant: Penetrating oil or cutting fluid to reduce friction and improve drilling efficiency.
- Penetrating Oil: To loosen seized or rusted locks.
- Clean Rag or Paper Towels: To wipe away shavings and excess lubricant.
- Flashlight: To illuminate the work area for improved visibility.
- Vice or Clamps: To secure the lock in place for drilling.
Additional Considerations:
- Choose the correct drill bit size based on the type of lock and pin sizes.
- Secure the lock in a firm position to prevent movement during drilling.
- Drill at a slow and controlled speed, applying gentle pressure.
| Lock Type | Pin Size Range | Recommended Drill Bit Size |
|---|---|---|
| Standard Deadbolt | 0.125″ – 0.188″ | 3/32″ – 5/32″ |
| Mortise Lock | 0.188″ – 0.250″ | 5/32″ – 3/16″ |
| High-Security Lock | 0.156″ – 0.281″ | 1/16″ – 9/64″ |
Selecting the Right Drill Bit
Choosing the ideal drill bit for lock drilling requires careful consideration of multiple factors:
Bit Material:
High-Speed Steel (HSS) bits are an affordable option for soft locks, while Carbide bits excel in durability and lifespan, making them suitable for tougher locks. Cobalt-infused HSS bits offer a balance of affordability and durability.
Bit Size:
| Lock Type | Drill Bit Size |
|---|---|
| Standard Pin Tumbler | 1/16″ or 5/64″ |
| Deadbolt | 1/8″ or 5/32″ |
| High-Security | 3/32″ or 1/4″ |
As a general rule, select a bit slightly smaller than the diameter of the lock cylinder pins. Refer to the table for specific recommendations based on lock type.
Bit Length:
The drill bit should be long enough to reach the back of the lock cylinder. Most standard locks require a bit length of 1″ to 1.5″. For higher-security locks, consider a longer bit of 2″ or more.
Replacing the Lock Cylinder
1. **Remove the screws.** Locate the screws holding the lock cylinder in place and remove them with a screwdriver.
2. **Pull out the cylinder.** Gently pull the lock cylinder out of the door.
3. **Disconnect the wires.** If the lock cylinder is connected to wires, disconnect them.
4. **Insert the new cylinder.** Insert the new lock cylinder into the door.
5. **Tighten the screws.** Tighten the screws that hold the lock cylinder in place.
6. **Connect the wires.** If the lock cylinder is connected to wires, connect them.
7. **Test the lock.** Insert a key into the lock and turn it to make sure the lock is working properly.
| Tools Needed | Steps |
|---|---|
| Screwdriver | Remove screws |
| Needle-nose pliers | Disconnect wires |
| New lock cylinder | Insert new cylinder |
Testing the Lock
Before drilling out a lock, it’s essential to test it to determine if it can be opened without drilling. Here are some steps for testing the lock:
1. Visual inspection: Examine the lock for any signs of damage or tampering. Look for bent or broken parts that may indicate a compromised lock.
2. Jiggle the handle: Gently jiggle the door handle while applying pressure. If the lock is loose or damaged, the handle may move slightly, even if the key is not inserted.
3. Listen for clicks: Insert a tension wrench into the keyhole and apply tension. Then, insert a pick and attempt to manipulate the pins inside the lock. Listen for any clicks that indicate the pins are setting.
4. Try a bump key: A bump key is a specially designed key that can open certain locks without the original key. Insert the bump key and strike it with a hammer or other blunt object. If the lock opens, it means it is a bump-able lock.
5. Use a decoder: A decoder is a tool that can read the key code imprinted on a key. Once the key code is obtained, a locksmith can create a new key.
6. Call a locksmith: If all other methods fail, it’s best to call a professional locksmith. Locksmiths have the skills and tools to open locks without damaging them.
Additional Tips for Testing the Lock:
• Be patient and persistent when testing the lock. It may take several attempts to find a successful method.
• Avoid using excessive force, as this can damage the lock or the door.
• If you suspect the lock has been tampered with, do not attempt to open it yourself. Call a locksmith immediately.
