How to Drill Out a Deadbolt: A Step-by-Step Guide
Deadbolts are a common security feature in many homes and businesses. However, over time, they can become jammed or damaged, making it necessary to drill them out. This process should be approached with caution, as improper drilling can cause damage to your door and lock mechanism. In this guide, we'll walk you through the process of drilling out a deadbolt step by step, ensuring you have the right tools and techniques to get the job done safely and effectively.
Tools You'll Need
Before you start, ensure you have the following tools on hand:
- Drill (preferably a cordless one for ease of use)
- Drill bits (a set of varying sizes, including a center punch bit)
- Hammer
- Center punch
- Safety glasses
- Work gloves
- Chisel (optional, for removing excess material)
Step-by-Step Guide: Drilling Out a Deadbolt
Step 1: Preparation
Begin by removing the doorknob and any decorative escutcheons (covers) around the deadbolt. This will give you clear access to the lock mechanism. If the deadbolt is still turning, try to unlock it with a key or using a manual override tool. If it's completely jammed, proceed to the next step.

Step 2: Mark the Center
Using a center punch, mark the center of the deadbolt's face. This will serve as a guide for drilling. If you don't have a center punch, you can use a nail or a small drill bit to create a starting point.
Step 3: Drill a Pilot Hole
Start drilling a small pilot hole (around 1/8" or 3mm) using a drill bit that's slightly smaller than the diameter of your deadbolt's face. Drill slowly and steadily, applying even pressure. This hole will help prevent the drill bit from wandering and damaging the lock mechanism.
Step 4: Increase the Drill Bit Size
Once you've drilled the pilot hole, switch to a larger drill bit. Gradually increase the size of the bit as you drill deeper, creating a larger hole in the deadbolt. Be patient and take your time to avoid overheating the drill bit or damaging the lock mechanism.

Step 5: Remove Excess Material (Optional)
If necessary, use a chisel to remove any excess material from the drilled hole. This can help create a cleaner, smoother surface for the new deadbolt. Be careful not to damage the surrounding area.
Step 6: Finish Drilling
Continue drilling until you've completely removed the deadbolt. You may need to switch to a larger drill bit or use a hammer and chisel to break through the remaining material. Once the deadbolt is removed, you can clean up the area and install a new lock mechanism.
Safety Tips
Always wear safety glasses when drilling to protect your eyes from debris. Additionally, consider wearing work gloves to protect your hands from injury. If you're unsure about any part of the process, don't hesitate to consult a professional locksmith.
Drilling out a deadbolt can be a challenging task, but with the right tools and techniques, you can successfully remove a jammed or damaged lock. By following this guide, you'll have the confidence and knowledge to tackle this project safely and effectively. Happy drilling!
