Protecting your home from burglary

  • Install double cylinder deadbolts (also referred to as a double sided deadbolt) on any and all doors with a glass section or on doors located near a window. A double cylinder deadbolt is one that requires a key on the inside to lock and unlock the door. If the glass is broken and the thief try’s to reach in and unlock the door, they’ll quickly discover they need a key.
  • Secure your doggy doors when leaving town or putting Fido in the kennel. Dogs make a great deterrent for thieves, they simply continue on looking for an easier target. But when Fido passes away and it’s obvious that you no longer have a dog, make sure that you secure or completely remove the doggy door. Have a well-lit entrance with motion detectors and trim any shrubs around your doors and windows.
  • It’s virtually impossible or at least extremely expensive to make your home 100% burglary proof. The main goal is always to make your home a less attractive target than the other homes in your neighborhood. Look at your neighbor’s homes and see what they’ve done to beef up security, if everyone has two deadbolts on their front door and you only have one, you might consider having a locksmith add a second one to yours as well.

Protecting your business from burglary

  • If the entrance to your business has double doors, these are usually installed with a 3 point locking system. It’s not un-common for one of those points to fail and most people think they’re just as secure with 2 points. They’re NOT! You can usually have this repaired for less than $100.00 which is far less expensive than discovering that a thief was able to gain access to your business.
  • Know what types of locks you have and what options are available. Flip bolts, hook bolts, dead latches are the three most common types. Does your door need a latch protector? Anti-wrench collars can be added to your mortise cylinders for less than $5.00 and it can prevent a thief from using a pipe wrench to break open the front door lock.
  • Have a high end security lock and security system monitoring the front door and windows and you think you’re safe? We’ve seen thieves break into the office/business adjacent which had no protection, then cut through the drywall and gain access without ever setting off the alarm system. It happens more than you think.
