Bump Keys are special keys which can open practically any rim cylinder lock. They are special locksmith tools but recently there have been reports of homes being broken into by thieves using bump keys which are freely available to buy online. Perhaps the most unsettling thing about this is it allows a thief to gain entry as easily as if they had your own house key - silently and quickly. It is possible to have anti-bump locks fitted which will prevent your locks from being compromised this way. Give us a call if you would like to discuss this option.
