A Few Inexpensive Ways to Theft-Proof Your Home

Home safety starts with common sense. Check out these inexpensive ways to make your home more burglar-resistant without spending a fortune.

1. Reinforce Your Entry Door Strike Plate---Reinforcing your door's weak spot, the jamb, with a heavy-duty strike plate and extra-long screws gives it the added strength needed to withstand a burglar trying to kick in your door. If your dead bolt was installed within the last 10 years, it's probably already reinforced. To check, simply remove the strike plate. If it's heavy steel with at least 3-in. screws or has a heavy reinforcing plate, you can rest easy. If not, buy strike plate-reinforcing hardware.

To install, remove the old strike plate, then hold the new one in place and deeply score around it. Chisel out space for the new plate, then mount it by driving 3-in. screws through pre-drilled holes.

2. Secure Patio Doors---Patio door locks are easy to pick. Placing a heavy-duty stick in the door track will bar the door closed, but it looks crude and it's inconvenient to remove every time you want to open the door. Fortunately, there's a better way to get the security you need.

Andersen Corp.'s auxiliary foot lock (andersenwindows.com) fastens along the bottom of the door and has a bolt that fits into a grommet to hold the door secure. A similar lock, the Door Guardian (thedoorguardian.com) attaches at the top of the door. Both locks allow the door to open 3 in. without compromising security. Installation takes about 10 minutes. Screw the bracket containing the pin to the door, then drill holes and insert grommets in the track for the pin to slide into.

3. Add Inexpensive Door and Window Alarms---Keeping doors and windows locked is your first line of defense. Make wireless alarms your second. Burglars hate noises, so even a small alarm usually sends them running. The alarms are available at home centers. Or check out Intermatic or Door and Window Alarms. The alarms don't provide the same security as pro-installed monitored systems since the wireless devices are activated by doors or windows opening (not glass breaking). Use the alarms for doors and windows in "hidden" areas of the house where you don't normally gather and that are often dark.

Attach the alarm to the door or window (with a screw or double-sided tape) alongside the magnetic contact strip (they don't have to be touching, but within 1/2 in.). When the door or window opens, breaking magnetic contact, the alarm shrieks (these little units have a piercing alarm). The door alarm has a delay feature, giving you time to set the alarm and leave, then open the door and deactivate the unit when you come home, without setting it off. The window unit has an on/off switch. The alarms will work on any door or window, and the batteries last two to three years.

4. Put Motion Detector Lighting Anywhere--- Put motion detector lighting anywhere. Motion detector lights are a proven crime deterrent, and standard hard-wired models cost as little as $15. If running a power supply would be difficult, buy ones that run on solar power. The downside is the cost. A Heath Zenith model shown here (the SL-7001) costs $80 (heath-zenith.com).
