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.
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. Furthermore, keyed locks are better protected against shimming than combination locks.

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.

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.

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.
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.
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.
