Lock bumping is a silent, undetectable method of home, business or storage facility invasion. The perpetrator can walk in though your front LOCKED door quite easily and quickly! Because this method of invasion leaves no evidence, insurance claims might be denied. This method of crime is currently being taught on web sites to anyone who looks for this information. The tools used to perpetrate this crime are readily available for purchase from Internet sales and are cheap to buy.

There are three types of locks available today, electronic, mechanical and a combination of both electronic and mechanical. In reality, electronic locks have a mechanical component, a latch, pin or bolt that moves in or out of place to allow a door to swing open.

Typically, quality locks are purchased from good locksmith establishments. Many of the locks listed below are not sold at Home Depot or Lowe’s.

Look for a lock that meet the Underwriters Laboratories UL437 standard.

“For those of you that are not familiar with UL437, this is the “higher security” standard for cylinders that are employed in government, business and by some consumers. These cylinders are by definition supposed to be resistant to covert and forced methods of entry for specified minimum times. UL437 is touted by high security lock manufacturers as one of the primary criteria to assure certain minimum levels of physical security in their rated cylinders.”

Following is a list of lock sets offered by manufacturers that claim they are bump proof:

Videx Cyberlock This system is electronic, sophisticated, and expensive (about $200 to $300 for each lock and keys can cost $100 each). This is a high end product with capabilities most home owners will not need. Their low end product should be considered for the home owner looking for top end solution.

This is a lock system intended for businesses. The key holds the power source for this lock system. The key holds a battery that needs to be replaced once a year. The key is more bulky than the typical house key. This system is pick and bump proof due to its inherent design. The system can offer the following options (at higher cost):

  • Scheduled open and close times.
  • Lost key deny access.
  • Delayed access.
  • Multiple key required to access.
  • Audit trail

Evva MCS The company sent us this e-mail: “We don’t have any distributor in the US, our products are
produced for the European market, according to the European standards. As the US market requires different standards we are not able to supply our cylinders for your market.
Our standards are Europrofile, oval or swiss round cylinders, Scandinavian cylinders and some special profiles for European countries.”

Abloy Protec A very complicated mechanical key and lock system.

  • A statement from one of their sales persons:

“Abloy lock works on a rotating disc principle similar to a bank vault tumbler, when you insert a key it has no effect on the lock it’s the 90 degree turn of the key that unscrambles the discs, if the combination is wrong it will not turn any further then 90 degrees. Pin tumbler locks when your key is inserted the combination is either correct or incorrect, the pins are always ready to be bumped up to align them, Abloy Protec locks are also Pick-Proof and we are the only lock manufacturer to make completely hardened steel locks with drill protection as opposed to brass with drill protection like our competitors.”

Mul-T-Lock The web site for this manufacturer is located here: http://www.mul-t-lockusa.com/ Cost for the lock is around $100 and a key might cost close to $20. This lock is mechanical. Quite close to being comparable to Medeco. Key bumping video can be found here: http://www.mul-t-lockusa.com/movies.asp

Farpro CX-5 (Scorpion)The web site for this manufacturer: http://www.farprosecuritysolutions.com/ This lock is mechanical and is thought to be comparable to Medico but much less expensive for lock and key.
Medeco These locks are expensive but have a very good reputation. There are two sets of pins, each set offset from the other to foil the bumping process. They are drill resistant.

Quickset Smart Keys (we have yet to confirm their method for preventing lock bumping). Allegedly, not a fully UL437 rated lock.

One question to ask when comparing locks to buy is the cost to buy a new key. One local locksmith claims that Farpro Scorpion keys only cost about $6 to make while a Medico key might cost close to $15.

Another factor to beware of is the warranty period of the lock. Some locks come with only a few year period while other locks extend the warranty well beyond. Know what exactly the warrantycovers and get it in writing.

One option for you to consider is having special bump resistant pins installed into your existing locks. If you take the cylinder into a lock shop the cost will typically be less than $20 for each cylinder. Call the locksmith first to see if they offer this service. For a locksmith to drive to your home or business and change out the pins will typically cost around $110 or more.

We recommend that you consult with a local reputable locksmith for advice to protect your home and business.

After you buy a lock, keep all documentation, warranty and receipts together in a folder for future reference.
