How To Drill Out A Deadbolt Lock: Step-by-Step Guide from the Pros

Published Date: Oct 23, 2025

When you’re locked out and there’s no other way in, drilling a deadbolt lock can be a last resort. It’s not ideal — it damages the lock and should only be used as a last resort. Before picking up a drill, it’s important to understand the right technique to avoid unnecessary damage to your door. This guide from Sure Lock & Key walks you through how to drill out a deadbolt lock safely. We’ll cover the tools you’ll need, the steps to follow, and when it’s better to leave the job to a professional home locksmith to ensure a clean, more controlled result.

Is Drilling a Deadbolt Lock Really Necessary?

Before grabbing the drill, think about whether it’s the right move. Many modern locks are designed to resist tampering, and there are often safer ways to get back inside.

If you’re locked out, ask yourself:

– Do you have a spare key somewhere?
– Can you get in through another entry point?
– Could a home locksmith help you get back in without damaging the lock?

If the deadbolt isn’t broken and both sides of the door are accessible, you may be able to remove the deadbolt manually without drilling.

If none of these options work and you’re trying to remove a deadbolt without a key, drilling should only be a last resort.

What You’ll Need Before You Begin

Drilling a lock isn’t complicated, but it does require some prep. Here’s what you’ll need:

Cobalt drill bit (essential for cutting through hardened steel)
Power drill
Center punch (to mark the drilling spot)
Safety glasses
Screwdriver or pliers
Patience and a steady hand

Using a center punch will help you keep the cobalt drill bit steady so it doesn’t slip and damage the door.

Step-by-Step: How To Drill Out a Deadbolt Lock

Ready to get started? Here’s how to drill out a deadbolt lock safely:

1. Locate the Lock Cylinder.

The lock cylinder is the part where you insert the key. That’s your target.

2. Mark the Spot with a Center Punch.

This prevents the drill bit from slipping. Place the center punch right in the middle of the lock cylinder.

3. Start Drilling with a Small Bit.

Begin with a smaller cobalt drill bit to create a pilot hole. Go slow and steady.

4. Switch to a Larger Bit.

Gradually use bigger bits until the pins inside the lock cylinder break apart.

5. Remove the Lock.

Once the lock is damaged, you can turn it with a flathead screwdriver or pry off the housing.

6. Check the Door for Damage.

Always check that no structural damage occurred. If you plan to install a new lock, clean out the hole first.

Other Ways to Remove a Deadbolt Without a Key

Sometimes drilling isn’t your only option. You might be able to:

– Call a professional locksmith for a safer, damage-free approach
– Try picking your deadbolt lock (only if you’re familiar with the technique and it’s your own property)
– Remove the lock’s screws if they’re exposed
– Tap the cylinder out, if it’s already loose

In many cases, especially with smart locks or high-security setups, it’s nearly impossible to drill a lock out without causing major damage. A trained expert from Sure Lock & Key can help assess the situation and resolve it quickly.
