"The employee got lost on his way to my house, and he showed up one hour late. He was very nice, though, and called to let me know that he was on his way. He changed five locks in my doors and gave me four sets of keys. He accidentally put one of the locks on backward, but he corrected it. The locks and keys work well."

Home Security Systems questions, answered by experts

A deadbolt has a different design, construction, and security level than a regular lock. Regular locks are mostly used for interior doors around the home, like bedrooms and bathrooms, and they usually include a locking mechanism on the inside. While regular locks are easy to use and install, they provide little security. 

A deadbolt adds a layer of security and is most commonly used on exterior doors. The installation is typically more complicated, but they hold up to wear and tear.

This is the topic of much debate, though there is no “better,” as it depends on personal preferences. Some of the components of a wireless system keep working when the power goes out, as they are battery-powered. On the other hand, a wireless system typically connects to your modem and router. Wired systems use landlines to communicate, which never go out on their own unless they’re physically cut.

Yes, keyless locks can deter burglars, mostly because they boost security and offer advanced features. Most models allow for unique codes or temporary access, making it harder for intruders to break in. Many of these smart locks even alert you if someone tries to tamper with them. However, you need to remember that while they provide an added layer of protection, no lock is completely foolproof. Pairing these locks with good security habits—like proper lighting and surveillance cameras—creates a strong defense to help stop intruders in their tracks.

Standard residential deadbolt locks come with a steel bolt that locks your door into place using a key (or keypad) on one side and a thumb turn on the other. When you lock it, the bolt slides into a strike plate on your door jamb to secure your door shut.

Various types of deadbolts are available, from the classic single-cylinder lock to a double-cylinder, rim deadbolt, smart deadbolt, and electronic deadbolt lock. Most homes in the U.S. use a single-cylinder deadbolt lock, which requires a key on the exterior and only a thumb turn on the interior to open or close the lock.
