Lock bumping is not a new lock picking technique, but it has attracted some press lately.
Lock bumping is the lock-busting practice of using a specially-crafted key to open a pin tumbler lock.
Most homes feature these types of lock exclusively.
According to Wikipedia, a “cheap” lock may actually offer better protection against lock bumping than a pricey one.
When changing the locks around the house, the safest option is to use a trained locksmith who can advise you about choosing the best locks at the best price for your home.
