Some mechanical or electronic locks do not use a key at all. This makes them completely immune to key bumping. The most secure example would be the Kaba Mas CDX-09, which uses a dial outside like a safe lock. Sargent and Greenleaf offers the "Brute" mechanical rim lock to compete with the CDX-09.
When executed correctly, lock bumping is effective in nearly 90 percent of all cylinder-type locks produced today. Perhaps one of the most disconcerting aspects of lock bumping is that it can often go undetected, which means that your home can be broken into without any signs of forced entry.
Bump-Proof Locks
These high-security locks don't rely on the pin tumbler locking mechanisms and are designed to be nearly impossible for burglars to pick or bump.
Lock bumping is a lock picking technique for opening a pin tumbler lock using a specially crafted bump key, rapping key or 999 key.
Not all locks that have keys are the same; a locking cylinder can be used to secure something as simple as a child's cash box or as complex as a warehouse full of expensive goods. Deadbolt door locks are the most secure type of key lock and are usually used on a home's exterior door.
Deadbolt door locks are the most secure type of key lock and are commonly used on exterior house doors. Single and double cylinder locks are classified by strength from Grade 1 to Grade 3. Grade 1 is the highest and provides the best security.
Unfortunately, the spring does not provide much security and it can easily be forced. Deadbolts, however, are still vulnerable to lock picking. Pin and tumbler locks are the most common designs in use today.
Anti-bump locks work by having more pins and specially made keys, having shallow pin stacks to prevent them 'jumping' up or locks that have programmable side bars and no top pins. Locks that use rotating disks also protect against bumping, keeping your door securely shut.
Lock picking is to use special tools to open a deadbolt lock through the keyhole and requires some skill. That's why lock bumping – using a specially crafted bump key as a tool – has become so popular among burglars. It's quicker, requires no skill, makes very little noise, and leaves no trace.
Lock snapping is one of the most common burglary methods, and it has been estimated around 27% of all burglaries are through snapping the lock. Lock snapping occurs when force is applied to the outside of the cylinder, using mole grips or similar.
Use a Strong Deadbolt
Security pins will be enough to discourage most criminals who probably aren't very good at lock picking, to begin with. Additional pin stacks also increase the time required to pick a lock. Most deadbolts will come with 4 to 5 pins, but you can also find cylinders with six pins.

Each key has a complex rounded shape, this coupled with the magnetic element makes it an extremely hard lock to pick. The only way to gain access to the door would be for the key to be cloned, and in that case, a master locksmith would need to get their hands on the original key.
Lock picking is a combination of skill, training, practice, specialist tools and patience. However, trust us, that is not the profile of the typical UK burglar. UK burglars are not highly skilled, trained lock pickers. They are thugs who try and batter their way through your door and lock.
No, there are many locks that can't be picked. But that doesn't mean they can't be defeated in other ways. ABLOY disc cylinders have traditionally been unpickable due to their complexity, and number of unique combinations.
Bump Key Set - Individual Dimple Bump Keys
We changed the game when it comes to bumping locks and our range of individual dimple bump keys continue that tradition. These keys are machine cut to code to our exact specifications, meaning these hard to pick locks can be overcome with a few taps.
The second, and easier, way to spot anti-snap locks is via visual inspection. Check your door lock for the three-star kitemark logo to check whether it is tested to the right standard. This mark might be on the front or along the side of the cylinder.
These security cylinders feature anti-snap lines so if force is applied to either end of the cylinder the intruder will break the lock at the anti-snap line and not at the center of the cylinder. This leaves the locking mechanism intact and will prevent the intruder from breaking the lock.
Squire TC22/5 Chain with SS100CS Padlock
The Squire TC22/5 and SS100CS Padlock and chain set achieves the highest Sold Secure rating of Diamond. This is the toughest chain and padlock combo on the market.
So what can you do to protect your home against lock bumping? The answer is to get rid of your traditional pin-and-tumbler locks as soon as you can and replace them with bump-proof keyless locks. One of the most effective bump-proof keyless locks on the market is the Lockey M210 keyless deadbolt.
A normal door lock is likely to be a mortice lock – either a deadlock, sashlock, euro sash case or euro deadcase style. These offer high security for external doors and also act as a visible deterrent because burglars know they're difficult to overcome.
Up to 30x's stronger than standard deadbolts
Ultimate Lock has the ability to withstand up to 4000 pounds of force, to put things in perspective, most deadbolts can only withstand roughly 100-200 pounds of force.
Any lock is vulnerable to force given enough time, and illegal entry is readily apparent. Most forceful attacks are directed at bolts and cylinders. Basic techniques for attacking bolts, such as prying, punching, and sawing are reviewed, along with which locks are the least and most vulnerable to these techniques.
