Many new homes only have one level of security, such as security. B. Bars. If the deadbolt wasn't set correctly or someone found your spare key/guessed your combination, they can gain entry into your home. The door can also be easily opened with your foot using a commercially available bolt. This security lock adds another layer of security. With tools in hand, installation takes about 5 minutes. They are easy to use with one hand. If you attach it more tightly (your choice), you may need to press the door lightly to lock/unlock it. You can find out when you test/install it. The screws provided may be fine, but like many which improve security, I opted for longer/stronger screws with this lock. The screws provided are screwed in the neck area, which is normal but loosens the area where the most stress is likely to be felt when someone tries to open the door with their foot. I used thicker unthreaded collar bolts for extra strength. For added strength I also replaced the original screws on the 4 door hinges (8 foot doors) with the same longer/stronger/thicker screws. Now both sides of the door are safer. We sleep better at night and worry less when we're away from home because we know it's safer at home. Of course, other measures such as window locks, cameras, security systems, etc. are also used. Can't be too sure.
