Why would a mobile locksmith need to drill through a lock? This may not be the prefered method but sometimes, there is no choice. Let’s take a look below at why a locksmith would drill through a lock.
If a lock cannot be opened by any other means, lock-drilling is a common method used by mobile locksmiths.
It is the last method of gaining entry to the lock. Lock-drilling may destroy the locking plug but not the locking mechanism. The locking mechanism will remain in working order even after the drilling.
You should always rely on a professional and experienced mobile locksmith for this type of work. They should have the right amount of training and equipment to deal with lock-drilling.
Here are the steps involved in drilling through a lock.
- Examine the Lock
- Use the Right Tools
- Attach a 3mm Drill Bit to the Drill
- Hammer a Centre Punch Just Above the Keyhole
- Drill a Hole Through the Lock Cylinder
Examine the Lock
The first thing is to examine the specific lock you plan to drill. Some residential locks are made with a steel centre pin while some others have a ball bearing in the middle pin to prevent drilling.
Drilling becomes ineffective in these types of locks. That’s why you should first examine the lock properly to see if it can be drilled.
In case the lock cannot be drilled, you may have to use alternative lock picking methods. You should be working with a basic tumbler lock to drill it more easily. Disable any alarms before you begin to drill the lock.
Use the Right Tools
Lock-drilling is a primitive method of opening a lock. You won’t need any sensitive tools to get the job done properly.
Make sure you have a variable-speed power drill that is powerful and well maintained. If not, you may find it difficult to drill through the lock.
You should always have different sizes of drill bits. You want the drill bit to match the size of the lock. So you should have several drill bits with you before starting the drilling process.
You can experiment with the drill bits when drilling the lock.
Attach a 3mm Drill Bit to the Drill
The 3mm drill bit should be the perfect bit to drill the lock. However, you may have to experiment with a few drill bits to see what works best for the specific type of lock you plan to drill. Use the 3mm drill bit to start with.
If you don’t have a 3mm bit, you can go for something that is in the neighbourhood. You want a drill bit that is relatively small to go through the locking mechanism rather than drilling it out completely.
Hammer a Centre Punch Just Above the Keyhole
The centre punch will create a guidance point for the drilling.
The guidance point should be just above the keyhole or immediately below the shear line – which is the dividing line between the outer and inner cylinder of the specific lock.
This will help keep the drill bit on the centre plug. There are lock-drilling templates to facilitate your decision of finding the right point to drill through.
Drill a Hole Through the Lock Cylinder
This will destroy the pins in the lock cylinder and allow you to force the lock open. Most common locks will have about five to six tumbler pins to drill through.
You will feel more resistance when the drill bit meets each pin. The resistance will decrease as the drill bit cuts through the pin.
Make sure you go slowly without trying to press too hard. Now insert a flat-headed screwdriver into the lock head and turn it in the same direction as you would with a key. The lock should open if everything was done correctly.
