ABUS Granit™ padlocks meet highest security standards and are considered to be among the most secure padlocks in the world. Their tensile resistance is over 6 tons. High-quality materials and careful finishing are the basis for the quality of these padlocks that are made in Germany.
ABUS Granit™: one of the world's most secure padlocks with a tensile resistance of over six tonnes. Granit locks have a tensile resistance of over six tonnes, making it almost impossible for attackers to release the shackle from the lock body by force.
This Stanley padlock is of security grade 4. Its body which is laminated hardened steel protects it against physical attacks. Since the shackle is also made up of hardened steel, the latter will resist other kinds of attacks such as cutting and sawing.
The most common high-security rating is UL437, which covers locks and cylinders. This category is tested for unauthorized opening from bypass, lock-picking, impressioning and destructive entry. Most major North American manufacturers supply UL437 listed locks and have patented and controlled key distribution available.
Lock Size. The bigger the lock, the more secure it is because thicker metals are more resistant to breaking. Also, larger lock bodies provide more space for additional pins or internal safety features, and internal locking mechanisms can also be larger and more robust.
Since they don't contain dials, keyed locks offer a superior level of security when compared to combination locks. Unless a thief has the key, he or she won't be able to open it.
CR's take: The Medeco Maxum 11TR503-19 is the strongest deadbolt across all of our lock categories. It rates Excellent for drilling, withstands kick-ins very well, and is designed in a way that makes it very difficult to pick.
The S&G 951 high security padlock has been tested and approved meeting military specification MIL-DTL-43607J and is available from DLA Land and Maritime.
Mortise locks are one of the most secure forms of residential hardware available today. What makes mortise locks so much more secure than their cylinder counterparts? A pocket cut into the short edge of the door, allows a longer and thicker mortise box to slide into the door itself, providing superior protection.
You'll want to make sure the lock size is big and the key has as many pins as possible to increase the security. Choose a padlock that features either carbide or alloy steel for the best security. The better the metal you have the more secure your padlock will be.
unless you find a chain that was used on a battleship anchor, that cable is gonna be the way to go. We use a relatively thin gauge and it takes much more time to cut it than it does to cut a chain. It frays really bad - so at least the potential thief might be detured knowing that cutting the cable will take some time.
Unpickable Locks Do Not Exist.
Also in the non-forced entry category, there is no doubt Schlage is better. With a better, more precise manufacturing process and 2 additional security pins than the Kwikset deadbolt, Schlage locks are significantly harder to pick, bump or compromise in non-destructive ways.
After almost 200 years of manufacture, Chubb Locks are one of the most trusted security brands on the market.
A Resistant, Bolt Cutter Proof Chain
By being the toughest chain, we mean the Pewag chain is the hardest chain to cut with bolt cutters. The biggest reason is the hardened steel chain is squared, so it will not allow bolt cutters to cut through it.
Large bolt cutters, which can be as long as 48 inches, can handle hardened steel rods, heavy chains, and thick threaded cable up to 7/16 of an inch in diameter.
Or are they more secure than traditional locks? The answer is that they can be. If a keyless lock means you're more likely to lock your doors every time you leave, less likely to hide a key underneath a doormat, or make tons of extra keys to share that you eventually lose track of, then yes, they can be more secure.
So, yes it's true: combination locks are less secure than keyed locks. But if you get a decent one with 4 or 5 dials and features that resist the most basic decoding techniques, then in the street, in most instances they are going to offer the same levels of protection as a decent keyed lock.
PROS: Dial Combination Locks have been around for over 100 years and are very secure and reliable. With the proper care and service, the dials/locks will last a long time. Combination locks are cheaper than a Digital Electronic Lock.
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.
