12 best locks and keys

Locks and keys are essential components of security and access control systems. They are widely used in various contexts, including home security, commercial establishments, and industrial applications. Here's what you should know about locks and keys:

  1. Keyed Padlocks: Keyed padlocks are portable locks that require a physical key to open and close. They consist of a lock body, a shackle (the U-shaped part), and a keyway. When the correct key is inserted into the keyway and turned, it aligns the internal components of the lock, allowing the shackle to be released or secured. Keyed padlocks are commonly used for securing gates, lockers, toolboxes, and more.

  2. Padlocks Hasps: Padlock hasps are metal fixtures designed to secure doors, gates, cabinets, and other openings. They often have a hole or ring for attaching a padlock. By looping a padlock through the hasp and the object being secured, you can lock it in place. This combination provides an extra layer of security beyond a basic latch or lock.

  3. Key Types: Keys for locks can come in various forms, including traditional metal keys, electronic key cards, and electronic key fobs.Electronic keys are commonly used in access control systems for buildings and vehicles.

  4. Lock Types: Locks can be categorized into different types based on their mechanism. Common types include pin tumbler locks, wafer locks, tubular locks, and disc-detainer locks. Each type has its own unique internal mechanism and security features.

  5. Security Levels: Locks are often rated for their security level. This rating takes into account factors like resistance to picking, bumping, drilling, and other forms of tampering. Higher-security locks are designed to withstand more sophisticated attacks.

  6. Master Key Systems: In some settings, like large apartment buildings or office complexes, a master key system is used. This system allows for multiple locks to be operated by different keys while a master key can open all of them. It provides convenient access control while maintaining security.

  7. Maintenance: Regular maintenance is important to ensure that locks function correctly. Lubrication, cleaning, and occasional replacement of worn-out parts are typical maintenance tasks.

  8. Security Considerations: When choosing locks for security, factors such as the lock's resistance to picking, bumping, and drilling, as well as its durability, are crucial. Different security needs may require different lock types and key systems.

  9. Locksmith Services: Locksmiths are professionals trained to install, repair, and maintain locks and security systems. They can also assist with key duplication and lockout situations.

In summary, locks and keys play a vital role in securing homes, businesses, and personal belongings. Understanding the types of locks and keys available, as well as their security features, can help individuals make informed choices to meet their security needs.

User questions & answers

Question: will these fit a 5 Pistol 18 Magazine Doro gun case
Answer: I don't know, but I know it fits my pelican gun case
Question: Does this fit a standard school locker
Answer: It will fit, but this is a relatively low-security lock. It's fine if you have nothing valuable or important in the locker (such as textbooks or electronics), but there are much better locks (eg. Master Lock 185d) that will fit a standard school locker.
Question: Has anyone used these as practice locks for picking
Answer: These are laughably easy to pick, especially with raking and zipping attacks. The biggest downside with this pack is that all the locks are the same
Question: so would i bought a 3 pack.. do i get a total of 6 keys? and those 6 keys would all work with 3 locks
Answer: No one wants to go to the hardware store...wait in line to get in and wait in line to have key(s) made during this time of COVID-19 particularly if you're over age 65 or immune compromised or both! So again, how many keys are included in a 3 pack? I bought ONE lock like this years ago and got two keys.

User questions & answers

Question: how weather resistant are they? Going on outside breaker box
Answer: These locks have a vinyl covered body for scratch resistance not for weather protection. They are recommended for indoor use. For more information regarding this product, or other Master Lock products please contact Customer Service Support at 800-464-2088
Question: Will there locks be small enough to fit through a bag's zipper pulls (2 circles on top of each other
Answer: Hello. This lock's shackle diameter is 3/16in. Please measure the hole on your zipper to ensure fitment.
Question: extra keys
Answer: To be clear, each 2-lock pack ships with two identical keys. Per "Keyed Alike" in product description, and "Same Key Opens Both Locks" on the packaging, either key will open both locks, so you can keep one with you and store the other in a safe place in case you lose your primary one.
Question: How wide is the space between the shackles? The distance from one leg of the U to the other leg
Answer: The distance from one leg of the U to the other leg IS 9X16 ths of an inch (or 4.5 x 8ths of an inch) just measured it for you ., Also note the distance from the lock flat part inside the hoop to the start of the hoop is again 9x16ths of inch. On the manufacturers speck it confirms 9x16th of an inch (shown as C: 9/16", grim) but remember if you are NOT fitting it to somthing round, say pipe, tube ect, you can not count the top part of the loop , so thats why the useable space for fitting around a flat item is only 9x16th of an inch, thats why I noted in my review that the lock sticks up when fitted to the case it is recommended for as the handle it goes through is square/flat not tubular.hope that helps, now back to fitting my kitchen sink.

User questions & answers

Question: So any of the keys will work for all twelve locks
Answer: Yes.I bought 2 - 12 packs sets (24 locks total) and they are all the same, so 1 key opens all 24 locks - I tested this myself and is what I needed for how I'm using the locks. This way I can open a bunch to stuff and only need to add 1 key to my Keychain. The item name shows "5PLS" which is the key "cut" so if you buy another 12 packs later on, you still only need the 1 original key.
Question: Can I get these with lock code A
Answer: The keys supplied are A389.
Question: If I purchased two packages, would all 24 locks be keyed alike
Answer: I’ll qualify my answer by saying that if the provider has a 24 piece offering, then yes they will all be keyed alike. I bought the 12 piece package and they were exactly what I needed. Good product, great Amazon pricing and delivery.
Question: i need 100 that are all keyed the same can I get this
Answer: why not? order 8 sets?

User questions & answers

Question: What is the silver made out of on the lock and keys? What type of metal and does it contain nickel or leaf
Answer: Once the combination has been changed , the "factory combo" no longer works. I set one up with a combo that I could not remember and could not get it to open even using the original numbers.Even the manufacturer did not or would not supply a "master code". Locks are very nice and work well.
Question: Are thay TSA approved
Answer: The key hole fits a universal TSA key that is used at airports only. It is pretty unnoticeable and really only used when traveling.
Question: Does one key open all the locks
Answer: Attach a lanyard through that metal loop and tie it to the bottom of the zipper pull. That way you won't lose your lock when it is open, or if the TSA does not close it properly.
Question: Is this brass
Answer: It has to be unlocked/on the correct code to switch to the mode to change the code. Summary of how to change code: 1. Enter correct/old code (starts at 000) 2. Move switch to other position 3. Enter new code you want 4. Move switch back to normal position

Product description

FEATURING BumpStop TECHNOLOGY - Lock bumping - a surprisingly simple method of breaking in through locked doors and padlocks - is undoubtedly the newest emerging threat to personal property security. And virtually all locks in use today are particularly vulnerable to bumping. Until now. BumpStop Advanced Cylinder Technology employs an innovative, patent pending design which utilizes a unique reverse rake tapered driver pin, high performance springs and tightly machined cylinder chambers. During a bump attempt, this design prevents the transfer of force from the bump key to the pins and therefore blocks rotation of the cylinder so that the lock remains locked.inquire and we can normally have them in a couple of days.

These locks feature the BumpStop Advanced Cylinder Technology. (for explanation see more product details below). The same lock with a shorter shackle is also available, search 6230NKA.
  • ATTENTION: If you order two 4-packs they will NOT necessarily be keyed the same. To ensure you get two 4-packs keyed alike, you must order the 8-pack.
  • APPLICATIONS: Industrial and manufacturing environments. it's a popular lock used by business owners to secure their storefronts and business gates. With Marine recreation uses, they will withstand the harsh elements. Utility meters, substations and cable boxes to name a few others.
  • DIMENSIONS: 2-1/2" (64mm) wide round solid steel body, each weighing 1.68 lbs. A 7/16" (11mm) diameter hardened boron alloy shackle with 2" (51 mm) inside height clearance.
