Make intruders have to work hard to enter your home with a deadbolt door lock, and chances are they'll turn their sights elsewhere for that easy payday.

Since securing your home against intruders begins with the right security door locks, here's what you need to know to help you make the best and safest choice for your home's entry doors.

The Best Locks for Your Front Door

Your home's front door should have a deadbolt in addition to a keyed door set. Look for a deadbolt with a 1-inch (2.5cm) throw bolt and an interlocking frame.

If your door has a window or a glass panel, secure it with a decorative grille that has nonremovable screws.  Or, install a break-resistant plastic panel over the window itself.

This is especially important if the window or glass is within an arm's length of the door handle, which could allow an intruder to break the glass in the window and reach inside to let himself in.

Cover the window with a curtain or shade to keep prying eyes out.

Always draw all the shades or close the blinds at night to prevent intruders from looking inside to determine what you are doing, whether you are alone - or whether anyone is home.

Knock Knock: Who's There?

Can you see the person on your doorstep before you open the door?  If you don't already have a peephole in your front door, a professional can easily install one when he or she comes to install your new dead bolt.

If you're handy, buy a peephole and install it yourself.

Choose the type with a fish-eye lens. Its wide-angle view allows you to see almost everything - and everyone - on your doorstep before you throw open that dead bolt and the front door.

Make sure your porch light is at least 40 watts to properly illuminate nighttime visitors.

Secure gate latches and garage and shed doors with sturdy padlocks that are designed to withstand rain and freezing temperatures.
