How to Drill Out a Yale Lock: The Comprehensive Guide
This guide provides a step-by-step approach to drilling out a Yale lock when other methods of entry have failed. It's important to note that drilling a lock should only be considered as a last resort, after attempting other methods like picking or using a bump key. Always ensure you have the right to access the property before proceeding.
Understanding the Situation
Before resorting to drilling, consider the following:
- Why is the lock stuck? Identifying the cause – a broken key, a faulty mechanism, or simple wear and tear – might suggest alternative solutions.
- Have you tried all other options? Lock picking, using lubricant, or even calling a locksmith are often viable alternatives.
- Do you have permission? Drilling a lock without proper authorization can have legal consequences.
Gathering Your Tools and Materials
Having the right tools makes the process significantly easier and safer. Here's what you'll need:
- Power Drill: A standard electric or cordless drill will suffice.
- Drill Bits:
- Pilot Drill Bit: A small drill bit (1/8" or 3/32") for creating a pilot hole.
- Larger Drill Bits: Progressively larger drill bits, up to around 1/4" or 5/16", depending on the size of the lock cylinder. High-speed steel (HSS) bits are recommended.
- Hardened Steel Drill Bit: (Optional, but highly recommended) A drill bit designed specifically for drilling through hardened steel components.
- Safety Glasses: Essential for protecting your eyes from flying metal shards.
- Work Gloves: To protect your hands and provide a better grip.
- Lubricant (e.g., WD-40): To help cool the drill bit and reduce friction.
- Center Punch and Hammer (Optional): To create a starting point for the pilot hole, preventing the drill bit from slipping.
- Replacement Lock: Having a new lock on hand will save you time and effort once the old one is removed.
Step-by-Step Drilling Process
This section provides detailed instructions on how to drill out a Yale lock.
-
Preparation:
- Put on your safety glasses and work gloves.
- If possible, lubricate the lock cylinder with WD-40 or a similar lubricant. This will help cool the drill bit and reduce friction.
-
Creating a Pilot Hole:
- Identifying the Drill Point: Locate the center of the lock cylinder. Aim to drill directly through the shear line (the point where the cylinder rotates). This is typically slightly above the keyway.
- Using a Center Punch (Optional): If you have a center punch, use it to create a small indentation at the drill point. This will help prevent the drill bit from wandering.
- Drilling the Pilot Hole: Insert the pilot drill bit into your drill. Start drilling slowly and steadily at the marked point. Apply gentle pressure and keep the drill bit straight. Drill through the first layer of metal, which is often the toughest.
-
Enlarging the Hole:
- Switch to a Larger Drill Bit: Replace the pilot drill bit with a slightly larger drill bit (e.g., 3/16").
- Drilling Carefully: Again, drill slowly and steadily, using the pilot hole as a guide. Apply gentle pressure and keep the drill bit straight.
- Using Lubricant: Regularly apply lubricant to the drill bit to prevent overheating and prolong its life.
-
Targeting the Pins:
- Progressive Drilling: Continue to increase the drill bit size in small increments (e.g., from 3/16" to 1/4" to 5/16"). The goal is to destroy the internal pins and allow the cylinder to turn freely.
- Listen for Changes: As you drill, listen for changes in sound. When you break through the pins, you may hear a clicking or grinding noise.
-
Turning the Cylinder:
- Attempt to Turn: Once you believe you've destroyed the pins, try to insert a screwdriver or a similar tool into the drilled hole and gently turn the cylinder. If the pins are sufficiently damaged, the cylinder should turn.
- If it Doesn't Turn: Continue drilling with a slightly larger drill bit and repeat the process.
-
Removing the Lock:
- Complete Destruction (If Necessary): If the cylinder still won't turn, you may need to drill through the entire cylinder. This will completely destroy the lock, but it will allow you to remove it.
- Removing the Lock Body: Once the cylinder is turned or completely destroyed, you should be able to remove the lock body from the door. This may involve unscrewing mounting screws or prying the lock free.
Important Safety Considerations
- Eye Protection: Always wear safety glasses to protect your eyes from flying metal fragments.
- Hand Protection: Wear work gloves to protect your hands and provide a better grip on the drill.
- Overheating: Avoid overheating the drill bit. Use lubricant frequently to cool it down and prevent damage.
- Bit Slippage: If the drill bit slips, stop and reposition it. A center punch can help prevent slippage.
- Patience: Drilling a lock can be time-consuming. Be patient and avoid applying excessive force, which could damage the drill or the door.
- Legal Considerations: Always ensure you have the legal right to drill out the lock.
Dealing with Specific Lock Types
While the general process remains the same, slight variations may be necessary depending on the specific type of Yale lock:
High-Security Yale Locks
- These locks often incorporate hardened steel components designed to resist drilling.
- Use a hardened steel drill bit specifically designed for these locks.
- Patience and steady pressure are crucial.
- Consider seeking professional assistance if you encounter excessive resistance.
Yale Mortise Locks
- Mortise locks are embedded within the door.
- Drilling the cylinder might only address one part of the locking mechanism.
- You may need to remove the entire mortise lock body from the door for complete access.
Troubleshooting Common Issues
Problem | Possible Cause | Solution |
---|---|---|
Drill bit keeps slipping | Inadequate starting point, dull drill bit | Use a center punch, replace the drill bit, start slowly with gentle pressure |
Drill bit overheating | Drilling too fast, insufficient lubricant | Reduce drilling speed, apply more lubricant |
Lock cylinder is very hard | Hardened steel components in the lock | Use a hardened steel drill bit, apply steady pressure, take breaks if needed |
Cylinder won't turn | Pins not completely destroyed | Continue drilling with a slightly larger drill bit, try different angles |

Yale Lock Stuck? FAQs
Hopefully, this FAQ section helps clarify any remaining questions you might have after reading our guide on drilling out a Yale lock.
What if drilling doesn't work, and the lock is still stuck?
Sometimes, the drill bit may slip or the cylinder may be too damaged for drilling. In this case, you might need specialized lock-picking tools or consider contacting a professional locksmith. They have experience dealing with stubborn locks and can offer solutions without causing further damage. Before further attempts to drill out a yale lock, consider the risks.
What size drill bit should I use when trying to drill out a Yale lock?
A good starting point is a drill bit slightly smaller than the diameter of the keyway. Gradually increase the size if needed, but avoid using a bit that is too large, as it can damage the surrounding door frame. Begin with around a 1/8-inch bit and work your way up to 1/4 inch if necessary.
Is it always necessary to drill when a Yale lock is stuck?
Not always. Before resorting to drilling, try lubricating the lock with a graphite-based lubricant. Sometimes, debris or corrosion inside the lock can cause it to jam. Also, ensure the key is fully inserted and try jiggling it gently. Drilling should be a last resort for how to drill out a yale lock.
What safety precautions should I take when drilling out a Yale lock?
Always wear safety glasses to protect your eyes from flying debris. Work in a well-lit area and use a drill that is in good working condition. Be cautious and avoid applying excessive force, as this can cause the drill bit to break or slip. It's also a good idea to wear gloves to protect your hands.
