 Is there a lock that can not be cut? -  No. All locks can be cut with the correct tool. However, some locks have special features such as shrouded shackles and unique body shapes that make them more difficult to cut. Some have Boron alloys or Stainless Steel that resists cutting but eventually if you want to cut it bad enough you will find a way!

What makes a padlock all weather?   -   A lock is considered all weather if the lock body, shackle and internal components are all made from materials that will not rust such as brass, stainless steel or aluminum. All locks including all weather locks should be lubricated once or twice per year with a non-petroleum based lubricant such as Lock Saver to keep them functioning properly.

How can I retrieve a lost combination? - A lost combination cannot be retrieved. When you reset the combination lock, it is best to record the combination for future reference and keep it in a safe place.

How do I find details of the lock sizes? -All our lock categories show a brief outline of the physical dimensions of those locks. In any individual lock to the more info tab and all details of the lock are given.

How many keys come with each lock? - At least two keys are included with each lock unless otherwise noted in the product page.

Can I reorder locks using the same key codes? - Yes. If you have ordered locks from us previously, we automatically try to match your locks on subsequent orders unless you request otherwise.

Padlock Basics

Shackle-The loop of metal that opens up to lock a device.
Body-The solid part of the padlock that contains the locking mechanism.
Locking Mechanism/Cylinder-Locks usually have a keyway where the key is inserted, or they may use a type of rotary mechanism or dial. 

Padlock Styles - Padlocks are used in virtually every business, organization and home. In order to fill the needs of these different groups, a wide variety of options and styles have been developed. The most popular styles of padlocks are the following:

Laminated-The body of a laminated padlock consists of multiple pieces of metal stacked on top of each other to form a tough, tamper-resistant lock.  They come in Brass and Steel. Many locks have a hardened piece on the top and buttom to provide additional security

Lockout Padlocks-Padlocks designed specifically for use in lockout programs typically have a provision on the lock to write the user's name and often come with only one key to limit access to the lock. These are also called management and audit locks. They can also be covered with paint or plastic to give individual colors to control the use of the locks.

Weather Resistant-Weather-resistant locks either have a shroud to protect the lock from the elements or are constructed from weather-resistant materials such as stainless steel. Although regular locks will work outside for a period of time, they tend to rust or corrode over time to a point where they can no longer be opened with the key or combination sequence.  If you are using the lock outdoors or are not sure where it will be used, get a weather resistant style. The cost difference is minimal.

Combination-A combination lock uses a rotary dial or series of buttons to unlock the device rather than a conventional key. Rotary combinations are usually three numbers and rotary wheels are usually four numbers.

Combination with Key Control -A combination lock with key control can be opened with a key or a combination. This type of lock is typically used in schools and locker rooms. The control key is capable of opening all the combination locks in that set.

Guarded/Shrouded/Shielded Padlocks-A guarded or shrouded padlock has solid metal guards that protect and surround the shackle on both sides, leaving only the top of the shackle exposed. The guards make it nearly impossible to cut the shackle with a bolt-cutter.

High Security-A high-security lock typically has one or more of the following options to increase its level of protection: 

  1. Hardened steel shackle
  2. Shrouded shackle
  3. Pick-resistant key cylinder
  4. Reinforced locking mechanism to resist prying

Keying Options- For most applications, the typical padlock that comes with two keys works well. However, there are many applications where different keying options are required. The most common keying options are:

Keyed Alike -The keyed alike option is where all the keys open all the locks in a set of padlocks. Every key and every padlock is exactly the same. If the padlocks are not sold in a set, they typically need to be purchased at the same time in order to be keyed alike

Keyted Different - Keyed different padlocks do not have duplicate keys in that set or on the order. Each padlock has a unique key that will not open any of the other locks in that set. As with the keyed alike option, if the padlocks are not sold in a set, they need to be ordered at the same time in order for them to be specifically keyed different.

Keyed differently locks are randomly selected from a group of locks with different key cuts. The number of keyed differently locks in the group depends upon the number of pins in the lock core and the manufacturer of the lock. Use this table as a guide:
3 pin core: from 10 to 40 Potential Key Combinations
4 pin core: about 250  Potential Key Combinations
5 pin core: about 1,100 Potential Key Combinations
6 pin core: over 5,000 Potential Key Combinations
Each lock is supplied with two or more keys. Lock models that are available keyed differently are listed as KD.

Keyed Different-Master Keyed-Master keyed padlocks are keyed different padlocks with the addition of a single master key that can open all the locks. The keys that come with the locks can only open that one lock, but an additional master key that will open all the locks in a series can be ordered separately. The master key and the master keyed padlocks must be ordered at the same time.

What are master keyed (MK) padlocks?- Some lock models are available keyed differently  with a master key override. The master key will open any of the locks in that group. The master key must be ordered separately. Lock models that are available with master key override are listed as MK. The keys that come with the locks can only open that one lock, but an additional master key that will open all the locks in a series can be ordered separately. The master key and the master keyed padlocks must be ordered at the same time

Rekeyable-The cylinder in rekeyable padlocks can be removed in order to (a) change the pinning or (b) replace the original cylinder with a new one, restoring security quickly and economically. This is ideal for situations where keys are lost or stolen.

Interchangeable Core Padlocks-These padlocks and door locks provide an instant security solution because they do not require disassembly to remove the core (cylinder). These are usually part of the higher security locks and are used in institutions where many locks are in use. The control key fits into the padlock just like the user key, but actuates the interchangeable core retaining mechanism to allow the removal and replacement of the core (cylinder). Interchangeable cores can be used in both padlocks and door locks for facility-wide security systems.

Non-Removable Key-The key cannot be removed from the padlock when the lock is open. This helps prevent users from accidentally leaving the padlock in the open position.

Reserved Key System -The reserved key system is not available to the general public but is a system where key blanks are cut and supplied directly through padlock distributors when requested by registered end-users. These locks are typically used by government and Larger companies.

Materials of Construction

Padlocks are made in a variety of metals and even plastics. Some of the common materials and applications for those materials include:

Plastic-Plastic padlocks are typically used in a light security situations where tampering is not expected to occur.

Aluminum-Aluminum locks are generally used in light security situations. The aluminum bodies are often anodized in different colors, allowing color-coding of lock systems.

Brass-Brass padlocks are more durable than plastic but are not as tamper-resistant as heavier steel padlocks. However, they do hold up to the elements and are often used as an inexpensive, weather-resistant light security lock.

Solid Steel/Case Hardened Steel-Solid steel and case hardened steel are very durable, cut-resistant materials. These types of locks are typically used in higher security applications and are often chrome or zinc-plated to help resist corrosion.

Stainless Steel-Like solid steel locks, these are very durable locks but stainless steel generally holds up to the elements better than solid steel.

Titanium-Titanium is an extremely durable metal that resists corrosion and is lightweight in comparison to solid and stainless steels. These are typically used in higher security applications.
