Top 30 Types of Keys and Locks

Who knew there were so many different types of keys and locks out there? Well, it’s all about providing the right level of security and usability in various situations. We are about to take you on a journey exploring 30 unique types of keys and locks. So, buckle up; it’s going to be quite a revealing ride.

1. Deadbolt Locks

Deadbolts are one of the most common types of locks you’ll find, particularly on residential properties. They offer excellent security due to the fact that they can’t be easily picked or forced open. The deadbolt lock operates on a “pin tumbler” mechanism, which means the lock cylinder is driven by a key’s series of unique cut depths. Some also include a keypad for an alternative form of access control.

2. Mortise Locks

Mortise locks are a popular choice for many homeowners and businesses alike. Named after the “mortise” hole into which they’re installed, these locks offer an extra level of protection because they’re not just attached to the door’s surface but embedded into its depth. A mortise lock typically comes with two different keys, creating an additional layer of security and making locksmithing a bit more complex.

3. Cam Locks

Cam locks may be small, but they can provide significant security. They’re often used in low-security applications like mailboxes and cabinets, and depend on the cam (a tailpiece attached perpendicular to the barrel) rotating to lock or unlock the mechanism. This lock type often uses either wafer or disc tumbler systems for added security.

4. Padlock and Shackle

The padlock and shackle aren’t affixed permanently to anything; instead, they’re portable and versatile. Operated by a key, touchscreen keypad, or combination lock, padlocks can be used on anything from lockers to garden sheds. Their removable shackle component affords them a high level of adaptability, while also providing potential vulnerabilities through bolt-cutting or shimmying methods of lock picking.

5. Disc Tumbler Locks

Disc tumbler locks, also known as disc detainer locks, employ a unique mechanism consisting of slotted rotating detainer discs. This locking type provides more pick-resistance than a typical pin tumbler lock and is commonly used in high-security products such as safes and ATMs. Though, they can also be found in lower-security products like bicycle locks and steering wheel locks.

6. Furniture Locks

Locks are not just for doors; they’re also used to secure furniture. Drawers, desk compartments, and filing cabinets often utilize furniture locks. Using either cam or bolt mechanisms to fasten, these locks ensure your precious documents or discrete possessions stay safe inside, protected from prying eyes.

7. Luggage Locks

No one likes the thought of someone going through their luggage uninvited. Small, portable, often employing combination lock mechanisms for ease and security without the burden of a key, luggage locks play an important role in keeping your possessions secure during travel. Recently, more advanced ones have sprung up using digital cards and biometrics like fingerprints for added security.

8. Rim Latch Locks

Rim latch locks are pretty common in older apartments and interior doors in homes. Attached to the inside surface of the door, they automatically lock the door behind you when it’s shut–perfect for those who sometimes forget to lock the door. Typically, rim latch locks also incorporate a deadbolt for better security.

9. IC Core Cylinder

When it comes to commercial properties and offices, interchangeable core (IC) cylinders are very popular. The biggest advantage of these locks is they can be rekeyed without disassembling the entire lock, saving time and effort if keys get lost or an employee leaves the company. Beyond key operation, they can often be augmented with more advanced technologies like smart cards or proximity cards for additional security.

10. Rim Cylinder Locks

Rim cylinder locks are mostly found in commercial properties due to their robustness and the higher level of security they provide. These locks almost always utilize pin tumbler mechanisms, but due to their size and configuration, they offer more pins – and therefore more combinations – than other types of locks. This adds complexity for any potential unauthorized lock picking endeavors, making them a strong deterrent against theft.

11. Night Latch Locks

Night latch locks are prevalent among apartment houses and residential spaces. They are mounted on the inside surface of your door, with a feature that keeps your door slightly ajar, allowing easy access without having to use keys. Known for providing convenient access control, they also provide an additional layer of security. The outside contains a “disc tumbler lock” mechanism operated by a key, while the inside has a knob or rotary dial mechanism.

12. Key Card Locks

In the universe of keys, key card locks stand out for their modern design and high-tech experience. Typically found in commercial buildings and hotels, they function using encoded electronic data stored on the card. When the card is inserted into the lock, the encoded information is read by the lock’s computer system to grant access. Different types of card technology exist, including magnetic stripe cards or proximity cards utilizing radio-frequency identification (RFID).

13. Electronic Compact Locks

Electronic compact locks sport sophistication with their advanced tech features and sleek designs. They may include touch screen or keypad mechanisms which allow you to input information like personal identification numbers to gain entry. More advanced systems may use smart key technology for control via your smartphone through near-field communication (NFC). These locks bring together cybersecurity and locksmithing techniques to keep your property safe.

14. Interchangeable Core Cylinder Locks

An interchangeable core cylinder lock allows you to change the key operating the lock quickly without removing the bolt from the door. This innovation in physical security engineering can be helpful in commercial settings where frequent key changes may be required – think tenants or staff turnover. A distinguishing feature is its figure-eight-shaped core housing, containing two types of keys: one for day-to-day operation, and another for changing the lock.

15. Double Cylinder Deadbolts

Double cylinder deadbolts feature a keyhole mechanism on both sides of the door, as opposed to having a turnable knob on the inside. They are highly secure options that can protect against “lock bumping,” a notorious technique used by burglars. However, their stringent security measure may impede a swift evacuation during emergencies if a key isn’t readily available. Consider safety guidelines and regulations before opting for this lock type.

16. Cylindrical Lever Locks

Cylindrical lever locks are renowned for their easy-to-use design. Instead of using traditional keys, these locks incorporate a lever-style handle which, when turned, actuates the bolt in the lock mechanism. They are commonly found in commercial buildings and meet disability compliance laws in several regions due to their ease of operation.

17. Mortise Cylinder Locks

Mortise cylinder locks are named after the ‘mortise,’ a cavity in which these locks are fitted into on doors. They’re excellent embodiments of security technology; versatile and robust, supporting multiple lock functions like passage, privacy or keyed entry. The lock’s mechanism usually involves a heavy-duty metal case installed inside the door, with an external trim (knob or handle), latch bolt, deadbolt, and key cylinder evident on each side of the door.

18. Euro Profile Cylinders

Euro profile cylinders (also known as DIN cylinders) feature unique design advancements each side having its keyhole – much like double cylinder deadbolts – but with the ability to operate separately. This means one key can open even if another is present in the opposite side’s keyhole: great for emergency situations where immediate access is needed. The lock’s robust design offers significant resistance against forced entry attempts.

19. Biometric Locks

Taking digital access control to the next level, biometric locks utilize human characteristics for identification and authentication. Top-notch systems employ fingerprint readers, facial recognition systems, or hand geometry scanners, complimented by high-capacity computer data storage for storing this information securely. From homes to offices to cabins, they offer swift and secure access without the need for traditional keys or PINs.

20. Jimmy Proof Deadbolts

The Jimmy Proof Deadbolt is highly resistant to forced entry attempts like prying or ‘jimmying’ due to its unique installation on the surface mount rather than being installed inside a door like other locks. When locked, the bolt interlocks with a jamb bracket preventing it from being jimmied open. It’s excellent for providing both peace of mind and an extra layer of security for your home or office.

21. Single Crossover Padlocks

You’ve likely seen single crossover padlocks while traveling or to secure mailboxes and school lockers. These locks feature a simple, yet efficient design. Their characteristic curve-shaped shackle crosses over the body, hence the name “crossover”. You can identify these locks with their U- or O-shaped metallic loops. They operate with key mechanisms where the key interacts directly with the locking mechanism by pushing it aside. Since these locks are often used in low-security applications, they are not built with advanced resisting techniques against picking, bumping, or drilling.

22. Bluetooth Enabled Locks

Welcome to the digital age of keys and locks! Bluetooth-enabled locks rely on modern technology for securing valuables and properties. Instead of traditional keys, these use digital keys sent via Bluetooth from a smartphone app. With your phone acting as your key, you say goodbye to misplaced keys! These locks add convenience without sacrificing security features – they can resist common lock picking techniques and provide real-time access tracking, allowing you to monitor who opens your lock and when.

23. Tubular Key Locks

Tubular key locks get their name from the unique round shape of their keys. The design includes a circular key with several slots along its edge aligning with pins inside the lock. The mechanism ensures higher resistance to picking attempts compared to regular pin tumbler mechanisms since each pin needs to be set to its specific height separately. Therefore, they offer high security and are often found on bike locks, vending machines or ATM machines.

24. Safe Deposit Locks

Your valuables merit top-notch protection like that offered by safe deposit locks! These complex locks require two separate keys for operation; one held by you (the box renter) and another held by the bank. Both keys need to be inserted and turned concurrently for the lock to open. Exceptional security, you might agree. They are exceptionally resistant to picking or forceful entry, providing an extra layer of security.

25. Vending Locks

Vending locks are typically used on machines that operate unattended in public spaces like candy dispensers, soda machines, or coin laundry systems. These locks must be secure enough to resist picking or breaking but also simple to operate for service personnel. Double sided or tubular keys are common choices due to their increased resistance to picking efforts. Bonus point – they can also operate on a master key system, allowing one key access to multiple locks.

26. Multiple Point Locks

If you’re particularly security-conscious, multiple point locks could be your best bet! As the name suggests, these types employ several locking mechanisms simultaneously—usually three points—spaced out along the door edge. Not only do they add several layers of protection, but they distribute the force from an attempted forced entry across the entire door frame rather than on a single point. Hence, doors with these locks resist being pried open!

27. Magnetic Keyed Locks

Sometimes hidden in plain sight, magnetic keyed locks use complex magnetic key systems instead of traditional mechanical keys. Magnetic bits in the key align with magnets in the lock leading to mechanical tumblers being pushed aside to unlock the lock. Incredibly difficult to pick or bump because they require a perfectly matched magnetic signature.

28. Mechanical Pushbutton Locks

Mechanical push-button locks offer secure and convenient access where frequent entry is necessary. Banks, schools, and hospitals often use these systems, which require a predetermined numerical sequence entered via a keypad. No keys to lose, or smart device needed. The code can be easily changed when needed, adding versatility to security.

29. Keyless Entry Padlocks

Embrace convenience with no sacrifice to security through keyless entry padlocks. No more fumbling with a traditional key! These locks are either number combination-based or use advanced technologies like fingerprint scanning, Bluetooth, or even WiFi. Always ensuring you’ve got easy access while keeping unauthorized users out.

30. Cylinder Interchangeable Core

The beauty of cylinder interchangeable core locks lies in their adaptability. The “core” (the part of the lock where you insert the key) can be easily replaced without disassembling the lock itself. This is particularly valuable for commercial spaces where locks need changing regularly for safety reasons (like change of staff), as it allows storing interchangeable cores ready to be deployed with minimum effort and downtime.

Wrapping it all up

Understanding the diverse array of keys and locks available is crucial not only for locksmiths but also for everyone aiming to secure their assets effectively. From the traditional padlocks to high-tech Bluetooth enabled systems, there’s always a perfect locking solution depending on your specific needs and context. Always take into account what valuables you’re protecting, their environment, and your convenience preferences when choosing your locks.
