Everything you need to know about padlocks

What is the difference between lock and padlock?

A padlock is a specific type of lock that is usually portable and typically used to secure objects or spaces that are not permanently fixed, such as gates, lockers, and storage units. It consists of a U-shaped shackle, a body, and a locking mechanism. Padlocks often require a key to unlock them, although there are also combination padlocks that can be opened using a numerical code.

The main difference between a lock and a padlock is that a lock is a general term encompassing various types of locking mechanisms, while a padlock specifically refers to a type of potable lock with a U-shaped shackle.

What is a key hole in padlock called?

The keyhole of a padlock is typically called a keyway. The keyway is designed to match the shape and configuration of the key that is meant to open the padlock. Combination padlocks do not typically have a keyhole. Many padlocks also have a pinhole at the bottom of the padlock, which is designed to allow water to drain away to prevent rust and ensure the padlock’s mechanisms continue to operate.

What is the safest type of padlock?

The safest type of padlock will typically be dependent on what it’s being used to secure. At UNION we offer a range of padlocks, from brass 5 and 6pin cylinder locks to high security steel close shackle padlocks. Although, no padlock can be considered completely impenetrable, those considered to be amongst the safest include:

- High security padlocks: these are often specifically designed with features to resist picking, drilling, and other forms of forced entry. They often incorporate advanced locking mechanisms, hardened steel shackles and anti-tamper features.

- Shrouded shackle padlocks: these padlocks have a protective cover or shroud surrounding the shackle, making it difficult for bolt cutters or saws to access and cut through the shackle. UNION offers shrouded shackle padlocks in its Cruiser and Battleship range.

- Disc detainer padlocks: these padlocks utilise a disc mechanism with multiple rotating discs instead of traditional pin tumblers, which can make them harder to pick. UNION offers a discus steel padlock, which is high security and suitable for outdoor use.

- Closed shackle padlocks: these have a smaller exposed shackle compared to standard padlocks, making them less susceptible to cutting. UNION offers a range of these including Hercules, a robust concealed shackle padlock.

- Biometric padlocks: fingerprint technology is used to open these padlocks.

What is the best high security padlock?

The best high security padlock will also depend on the location and use, for example will it be exposed to extreme weather conditions?

Typically closed shackle and steel construction padlocks are amongst the most robust and secure. In addition, products should be CEN tested and Secure by Design accredited, as well as holding the necessary weather-proof testing certification.

Are combination or key padlocks safer?

Both combination and key padlocks have their own advantages, and both can provide the right level of security. The choice between the two depends on factors such as personal preference, convenience, and specific use for the lock.

A combination padlock eradicates the needs to carry keys, which could be lost, but they may be vulnerable to manipulation techniques such as picking or decoding the combination. Plus, if a combination is forgotten, it can be challenging to regain access without contacting a locksmith or the manufacturer.

Key padlocks can provide strong security through advanced keying systems that are difficult to duplicate or pick. Some key padlocks also incorporate features like restricted keyways or patented key control. However, come keyed padlocks may be susceptible to attacks like lock picking, or forced entry using specialised tools. Losing or misplacing the key can also pose a security risk.

What should I look for in a padlock?

There are several things to consider when choosing a padlock.

1. Security level – depending on the level of security needed look for padlocks that are designed to resist common forms of attack. Higher-security padlocks often incorporate features like hardened shackles and anti-tamper mechanisms.

2. Material - consider the materials used in the padlock's construction – will brass work for you or do you need a stronger fabric? Look for options with robust bodies and shackles made from hardened steel, such as boron or other durable alloys, if you’ll need a stronger construction.

3. Shackle design – if you need high security opt for padlocks with a thick and sturdy shackle that offers resistance against modern methods of attack. Shrouded or closed shackles provide additional protection by minimising exposure.

4. Locking mechanism and key control – consider whether a smart or dumb padlock would be best for you, whether you need physical keys or a combination code

5. Weather conditions - If the padlock will be exposed to outdoor elements, check if it offers weather resistance. Look for padlocks with corrosion-resistant coatings or seals

6. Brand reputation – you should always chose a security product from a trusted supplier and brand

What are the dangers of losing the key to a padlock?

Losing a key to a padlock can pose a potential security risk, as well as causing inconvenience to the owner.

Lost keys run the risk of unauthorised access to a place or asset, as well as the cost and inconvenience of replacing them.

To mitigate the risks of losing a key to a padlock, it's important to take preventive measures, such as keeping keys in secure and designated locations, having duplicates of important keys, or using alternative access methods like combination padlocks or smart padlocks.
