Can I Drill Out A Lock?
There are a few things to consider before drilling out the lock. The first is the most important thing, the type of lock. You have to check the lock type you have. Tumbler locks are easier to drill through, but if it has any additional security devices, be prepared for some tough challenges.
You Should NOT
If your lock comes with anti-drill pins, think again before drilling. These locks can tackle this type of thing, and if you drill through the rotating cam just beyond the last pin, you won’t be able to open the lock at any cost.
Also, if your lock has a hardened steel pin or a ball bearing in the middle pin, these types of locks are too difficult to drill.
Precautions Before You Drill Out A Lock
Pick Up The Lock
You can use raking for picking a lock, especially if you are not sure of the type of lock you are dealing with. If you can’t feel the inner engineering of the lock and you don’t have sufficient knowledge of picking manually, try a pick gun. It will save you some time.
Bump The Lock
You can apply this method to certain types of locks. It is nothing new and was developed back in the ’70s to make it effortless for locksmiths to disassemble locks.
Slip a bump key two-thirds into the lock. Tap with a hammer in the correct spot on the key, and then the lock chamber should pop out. If you can not work out after 20 or so tries, it probably won’t, no matter how many attempts you make.
Bring a Replacement Lock
Make sure you have a replacement lock to slot in when you drill the lock.
Get The Owner’s Permission
When you drill through a lock, you will destroy it. So getting the owner’s consent is vital. Also, make them understand that you have tried every other necessary means to open that.
What Will You Need To Drill Out A Lock
You won’t need precision tools, but it does require a well-maintained drill and drill bit with multiple sizes.
- A drill with various speed settings.
- HSS drill bits. Start with a 1/8 inch bit for the initial hole and a 1/4 inch to step it up.
- A hole punch for helping the bit to get some guidance when you start drilling.
- A hammer for striking the hole punch.
- A Screwdriver (flat-headed) that fits the key slot of the lock.
- A plastic sheet for collecting the filings.
How to Drill Out A Lock
1. Hammer a Point For Guidance
At the top of the lock, place the punch just below the middle of the outer and inner lock. Sometimes it is called the shear line. This is the exact height you would need to drill into the tumblers.
With a hammer, create 2 or 3 firm taps on the end of the punch until there is a visible indentation.
2. Start Drilling
Now start drilling a hole through the lock cylinder using the 1/8 inch drill bit. This will destroy the pins inside the lock, help you to force it open. Most locks come with five tumbler pins, but there are some with six or more.
Each pin you hit will increases the resistance of the drill. You would feel this ease off as each pin gets drilled through.
3. Apply Steady Pressure
As you drill, don’t rush and apply steady pressure, ensuring that the drill is kept level at all times. Damaging the lock further is the last thing you would want. Set a low setting to the drill for an accurate job.
4. Change The Bit
Once you have drilled the first hole, switch to a ¼-inch bit or any size you think will fit. This will further break up the pins, making sure the lock is easier to open.
5. Insert The Screwdriver
Turn the mechanism using a screwdriver the same way you typically do with the key. When you drill accurately, the lock should turn. If not, you would need to take some destructive action.
6. Destroy The Lock Mechanism
Get 3/4 inch drill bit, and drill through the entire assembly. You could utilize a hole saw or a unique tubular lock bit if you want. That process should open the door.
How To Drill Out a Lock When a Key In It
When you’ve put the lock and can not get it out, drilling is the last thing you can do. It will damage the lock beyond repair if you get it wrong.
1. Choose The Right Drill Bit
Use a 1/4 inch bit and drill into the cylinder to the depth that the key is rest, as you can guess. The cylinder works as the bit of the lock that rotates when you twist the key.
2. Turn The Lock Mechanism
After removing enough debris from the lock cylinder, remove as much metal and any pins you can to so that you can turn the lock mechanism to unlock.
3. Buy a Replacement Cylinder and New Key
After removing the cylinder, please take it to a lock specialist to buy a replacement.
Is it Possible to Drill Out a Master Lock?
Yes, it is possible to drill out a master lock. However, it won’t work on all of them. Use a drill and a 1/4 inch drill bit and drill through the center of the mechanism. That way, it destroys the locking mechanism.
This is different for a tumbler lock because you are aiming for the upper part near where the key slot is.
Here the danger is the drilling won’t open the lock and will disable the lock forever.
Can a Lock Drilling Template Make The Drilling Easier?

They certainly speed up the process and make the task straightforward. They are widely available and vary with various lock styles, so it’s essential to know the type of lock you have.
