You might believe that a locked door ensures your safety, but have you ever heard of a bump key? This specially crafted tool can turn your sense of security on its head, making a locked door merely a slight hiccup for those in the know.
Bump keys are designed to pick the world’s most popular lock – the pin tumbler lock, which includes exterior door entry locks for homes. Intriguingly, each bump key is manufacturer-specific, meaning a full set would include one for each major lockset manufacturer.
Understanding Bump Keys
The Concept Behind Bump Keys
Bump keys, a term that might seem alien to many, are simple yet effective tools capable of revealing pin tumbler locks. Imagine the regular keys you use daily. Now imagine those keys with cuts at maximum depth, tailored to match specific lock manufacturers. That’s essentially what bump keys are – regular looking keys with a unique design twist.
These aren’t universal master keys; they’re manufacturer-specific. For instance, a Kwikset lock would require a Kwikset bump key, and the same rule applies across all major lock brands. So, if you were to have an entire set of bump keys, it would include one for each major lockset manufacturer.
How Bump Keys Work
The working principle of bump keys centres around the concept of ‘bumping’. It’s as straightforward as it sounds – inserting the specially designed bump key into the lock and then ‘bumping’ it with force to displace the pins inside the lock.
Here’s where it gets interesting. The force from the bump causes these pins to jump up above their shear line momentarily. During this brief period of disarray amongst the pins, turning the key unlocks the door – granting access without any signs of forced entry.
While this might sound complex in theory, in practice, it’s surprisingly simple and requires minimal skill or experience. But, remember not all locks can be bumped; this technique is effective predominantly on cylindrical tumbler locks that use moving pins.
History of Bump Keys
Origins and Evolution in Locksmithing
Bump keys stem from the locksmithing industry. Born out of necessity, these unique tools were first utilized by locksmiths who required a swift and efficient method to unlock cylinder locks. Cylinder locks, often featuring a pin tumbler mechanism, have been commonplace in residential applications for decades.
Regrettably, what started as a handy tool for professionals quickly became a weapon for criminals. With only minimal practice and few tools, burglars discovered that they could easily gain entry into homes fitted with these types of locks. The mass production of such locks facilitated the illicit use of bump keys, opening the door to deadbolts and standard key locks alike.
Over time, lock manufacturers recognized this growing threat to residential security and sought solutions to counteract it. Companies like Medeco introduced bump-resistant lock cylinders into the market. These innovative cylinders are designed such that duplicate keys are available solely through authorized dealers.
In response to this new technology, insurance policies have adapted too. If a home is burglarized using a bump key, the theft may or may not be covered depending on how the policy is written.
Even though advancements in technology and security measures, the use of bump keys continues to pose a significant challenge in maintaining residential safety. The ease at which these keys can be used highlights an ongoing need for homeowners to stay aware and proactive in their home security measures.
Risks Associated with Bump Keys
Usage in Burglaries
Bump keys aren’t just tools for locksmiths anymore. They’ve found their way into the hands of burglars who exploit their simplicity and effectiveness. Bumping a lock involves striking it repeatedly to dislodge the pins, allowing a specially cut bump key to turn the cylinder and unlock the door. This method is both fast and quiet, making it a preferred choice among thieves.
Also, certain clicking and vibrating tools designed specifically for bumping can also be used. These tools allow for rapid repetition of bumping, potentially revealing doors even faster. But, there’s a downside; the force of the bump can leave an indentation on the front of the cylinder.
Security Concerns for Homeowners
As a homeowner, you might find this information concerning. And rightly so! While some locks advertise ‘bump proof’ features, only a rare few key pin locks cannot be bumped. It’s critical to remember improving your home’s security doesn’t stop at installing any lock; investing in high-quality locks significantly reduces your vulnerability to break-ins.
Locksmiths can replace original lock pins with mushroom pins (also known as spool pins), enhancing your lock’s resistance. But, these will not render your lock entirely bump proof.
Companies like Medeco offer high-end bump proof lock cylinders with duplicate keys available solely through authorized dealers. Although these cylinders are pricier, they offer superior protection against bumping methods.
Finally, consider whether your insurance covers theft via bump key usage. If a burglary occurs using this method, coverage may vary depending on your policy terms.
Preventing Lock Bumping
As the world becomes more informed about bump keys and their threats, it’s crucial to take steps for effective lock bumping prevention. It’s not just about securing your premises; it’s also about having peace of mind knowing that you’ve done your part in ensuring your safety.
Choosing Bump-Proof Solutions
It’s not all doom and gloom, though. There are practical solutions available that can help protect against lock bumping. For instance, you can opt for a flip guard – a simple yet effective device designed to prevent lock bumping. You don’t even have to buy a new lock; you can improve your existing one by replacing the original pins with mushroom pins or spool pins.
Remember, while these pins enhance the resistance of the lock, they don’t make it entirely bump-proof. That said, companies like Medeco manufacture high-end locks offering bump-proof cylinders – a more robust solution but with an associated cost.
Enhancing Home Security Measures
Home security doesn’t end with locks alone. Your insurance policy is another line of defense against thefts involving bump keys. Some policies may cover such thefts even without signs of forced entry, but this varies based on how each policy is written. So, check with your insurer about coverage for theft involving bump keys.
Also, invest in overall home security measures such as alarm systems and surveillance cameras. These tools may not stop a determined burglar from trying to break-in, but they can act as deterrents and provide vital evidence if a burglary occurs.
