There is always a need in the locksmith industry to keep adapting, which is true when choosing a pick resistant lock and bump-proof lock.

Buying a lock is very delicate, as you are putting your and your family’s safety on a piece of metal. Selecting a poor security lock can put you through many awful situations and even make you call an emergency Miami locksmith to reverse the damage caused to your doors and property.

With so many options on the market, Locksmith in Miami will provide you with useful options to choose a highly secure lock that is pick-proof and bump-resistant. To avoid security concerns at your residence or business, consider a lock with pick proof and bump-proof features.

What is Pick Proof and Bump-resistant?

Pick-resistant and bump-proof locks can prevent bumping and lock-picking attacks. Burglars use bumping attack since it is a technique in which a uniquely cut key is inserted into the lock’s keyhole, forcing the lock’s pins to jump to create the shear line and rotate the core to open the lock.

Lock picking is a technique professional locksmiths use to open doors, but sadly, thieves use it to crack open locks without keys. Some refer to lock picking as “an art” as it involves some methods and tools (such as torsion wrenches, hook picks, pick tools, etc.), and it requires a handful of skills to open a lock and gain access to a property.

So, knowing all this, how do we choose a resistant or bump-proof lock?

Security professionals know that anything put on with tools can be taken off using the same tools. However, electronic locks are immune to picking and lock bumping attacks, as most do not use a key.

Electronic locks have different designs and styles. Early electronic locks used keypads with a PIN for entry. Though keypads are still popular, touchscreen panels have replaced the latter ones, including other security features that prevent code hacking.

Bluetooth-enabled locks work with the smartphone’s Bluetooth ID. These locks also have another electronic entry in case the phone’s battery dies.

The last type of lock is the biometric entry lock, which uses fingerprint identification and other biometrical recognition to open a lock.

Some of the best electronic locks in the market are:

1. August Wi-Fi Smart Lock

2. Schlage Encode Smart Wi-Fi Deadbolt

4. The Schlage BE375 Electronic Deadbolt Lock ($99).

5. The Kaba Mas CDX-10 ($1,700) is used by the federal government.



An Effective Option is to Buy a Pick-resistant Lock

If electronic locks are out of your budget, you can always choose pick-resistant locks. The difference between other lock and pick-resistant locks is that they have extra tumblers or locking devices that make them harder to manipulate with tools and are key-bumping resistant.

One of the most popular pick-resistant lock manufacturers is the Medeco, followed by Mul-T-Lock and the famous Schlage Primus. Yes, this lock uses a second set of pins, meaning that the key needs to do the job of two keys, which makes it impossible for a key bump to crack this one open.

High-security Locks

These locks have a keyhole but use special keys with complex shapes and angles that bump keys and standard blanks cannot duplicate. They also have additional features, such as sidebars, pins within pins, rotating pins, or interactive elements, making picking difficult or, for amateurs, almost impossible.

Some examples of high-security locks are

A bunch of keys

Although we do not recommend this as the only security measure to secure your home, having a unique keyway is one way to prevent key bumping.

Bump keys must have the same keyway as the lock to work. However, most bump keys don’t have unique key cuts compatible with uncommon keyways.

These locks have a keyhole, but they use a unique shape that is not widely available or compatible with standard bump keys or blanks. This makes it less likely that a burglar will have the right keyway to bump or pick the lock.

Some cheap examples of uncommon keyway locks are:

Medeco Lock

Medeco Maxum Deadbolt - Grade 1

An extraordinary pick-resistant lock is the Medeco Maxum High-Security Deadbolts. This lock uses high-quality materials such as stainless steel to stop most forced entry attacks. Also, it uses restricted keyways that limit unapproved keys’ danger. The Medeco lock works like other door locks — insert and turn the key.

However, Medeco battles lock-picking attacks by using a combination of specialty pins.  A few of these specialty pins are cut at different angles to make lockpicking more difficult. An expert locksmith can pick a Medeco lock; however, it is still difficult. So, amateur burglars or average Joe would need time and patience to bypass this lock.

Smart Locks

You can control a smart lock with your smartphone or another device, like a fob. Often, smart locks don’t have a key cylinder to insert a key. But a few bring one for an emergency, like a dead battery. Smart locks cost more than traditional locks. Yet, intruders cannot bump or lockpick these locks because they have no key cylinder.

You can program in various access codes or connect multiple devices for loved ones. Nonetheless, an issue to consider is that someone can hack these locks, so understand their pros and cons before buying a smart lock.

Bowley Pick Resistant Locks

An excellent pick-proof lock, for example, the Bowley deadbolt, is made from strong metal, so it’s resistant to forced entry techniques (hammers, drills, saws, and kicks). In addition, the internal mechanism of this lock uses security pins, just as warding, making the Bowley practically bump-proof and pick-proof door lock.

The Bowley lock combines security pins and tumbler locks with one large ward. This design blocks any attempt at bypassing the lock through lock picking.

Exploring the warding in this lock before engaging in the pin and tumbler part implies you need to insert the key, turn it around, insert it more so the key can engage in the pins, and then turn it around again. So, yes, it requires significant time, which could limit you during an emergency or when in a hurry. Nonetheless, it’s just a small price to purchase a high-security lock.
