Some people understand just enough about locks and security to make themselves feel better. As long as they know that they have a Schlage with a deadbolt installed they feel fine – giving no further regard to additional security or whether or not their security choices are effective at all. Many people don’t even want to think about the articles online that outline how easy it is to pick residential locks.
Despite how easy it is to wedge a car door open, the public just doesn’t seem to think that anyone would actually do so – and that’s far from the truth! Bump keys are very easily bought and even easier to operate. Car door wedges are just as simple to procure.
There is a math behind key codes that make it possible for people to create their own bump keys. These numbers also show how many unique combinations your lock can support. For example, Schlage locks have 9 depths and five key grooves, 9x9x9x9x9 = 59,049
Then there is the math behind key codes. Anyone can find the depth charts for the different lock companies (that makes it possible for anyone with a file and a ruler, to make a bump key). You can also get a key gauge to decode the more common key types. Based on that information you can see the amount of possible unique key combinations for your lock. Schlage has 9 depths, and an average of 5 grooves on the key. 9x9x9x9x9= 59,049. In comparison, the standard Master Lock has 8 depths and 4 grooves. 8x8x8x8 = 4,096.
The info means that one out of every 59,049 with your lock has the key to your it. One in 4,096 can open your Master Lock. It can be really alarming how similar the locks in your neighborhood are. If all of the homes in your neighborhood were built near the same time, there are likely some repeating key codes, as they were probably bought from the same place.
Car locks can be examined in the same way. Many older cars can be picked easily due to their limited number of unique key codes. There are often special tools available for easily breaking into locks made in the 1990s. Motorcycles can be compromised like this as well.
Newer cars are very hard to steal with the invention of transponder chips, key fobs and the like. Still someone can still have access to the contents of your car. Criminals sometimes take strange things, but it’s always better to have your belongings not stolen.
