Bolt cutters are the common tool of choice for to cut padlocks during forcible-entry. Unfortunately, most padlocks are made of case-hardened steel, which is very strong in comparison to the materials that bolt cutters were intended to cut.
You can use a variety of tools to break the lock, including a Dremel and angle grinder. Alternatively, you can cut the lock open with a torch or cut it with a hacksaw. Some cheaper padlocks can be pounded or pried open with a hammer.
A standard padlock, for instance, can be cracked using only a hammer, a screwdriver, or a pair of open-ended wrenches.
If you misplace your key or forget the combination to a lock, you may need to cut through the lock to get it back. Most steel locks can be opened by either using bolt cutters, an angle grinder, or a hacksaw.
To cut a lock, all you need is a pair of bolt cutters. Hold the lock at an angle as you cut through it, which will make the cutting process easier. You can also cut through a lock with an angle grinder. Make sure to put on gloves and a face shield first, since grinders can produce sparks.
Another handy way to cut a lock is to use a dremel tool. With a dremel, you will need a cutoff wheel, which is quite similar to that of an angle grinder. The best dremel tool usually is smaller than an angle grinder.
Picking a lock with paper clips works pretty much the same way as picking a lock with a traditional tension wrench and rake. You just need to turn two paper clips into those two very same tools, and then pick the lock with them like you'd normally do.
You might be able to take apart a mechanical pencil and use some of the sturdier metal components to pick a lock, but a wooden pencil probably wouldn't work. However, you can use pencil lead to lubricate a sticky lock if you don't have powdered graphite on hand!
This is a less hassle way on how to break a padlock without tools. All you need to do is find two wenches. Put both of their U-shaped clasp between the shackles and quickly pull closer until their handles meet. This will help in detaching the locking mechanism between the shackle and the body of the padlock.
Try bolt cutters.
If you want to try to cut open the lock itself, cut the shackle. This will not work on most master locks, as they are made of case hardened steel.
No, you can't cut a lock off of a storage unit. It's against our policies and, frankly, could cost you a lot more than just the cost of a new lock. (Especially if you accidentally damage the storage unit's door.)
To unlock a privacy lock you'll need a flathead screwdriver that is small enough to fit into the hole on the doorknob. Insert your screwdriver into the hole and push forward. If your doorknob is using a push-button type privacy lock, then you should hear a loud click and the door will open.
To penny lock a door you simply jam pennies between the door and the hinge from the outside, which prevents the door from opening from the inside. If done properly, the only solution is to remove the door from the hinge. While penny locking a door can work, it will only work with certain door jams.
When executed correctly, lock bumping is effective in nearly 90 percent of all cylinder-type locks produced today. Perhaps one of the most disconcerting aspects of lock bumping is that it can often go undetected, which means that your home can be broken into without any signs of forced entry.
Metal Types a Dremel Can Cut
As a general rule, sheet metal refers to steel, either galvanized or stainless. This metal is safe to cut with most commercially available cutting tools such as Dremel attachments.
The beauty of the Dremel 3000 is in its versatility. From cutting metal with Dremel tools, to engraving it and polishing it, a rotary hand tool can become an indispensable part of your jewellery tool kit.
