As the leader in home security, ADT can help you customize a home security system with easy-to-use equipment and special security features to meet your safety needs. We have service centers nationwide that can install an ADT home security system within 24 hours in most areas. Once your home is equipped with our top-of-the-line system, it is connected to a network of ADT Monitoring Centers nationwide which deliver non-stop security monitoring 365 days a year. All of our installation technicians are internal employees, and not third-party contractors. You can count on your Security Advisor to take the time to set up your system properly, help you understand how the system works, and help make sure your home and family are thoroughly protected.

"The alarm, when it goes off, is very loud!!! This is a good thing. If we ever need to activate it, it will definitely scare off anyone trying to come into our home. We can set it off from our phone or from the keyboard control panel that we installed in our bedroom. We feel very safe with this purchase."

"I’ve had nothing but problems with SafeStreets. The installation was a mess—took hours longer than promised, and the technician seemed clueless about the system. When I called customer service, they were rude and unhelpful. The security system itself is glitchy and keeps going offline. Definitely not worth the hassle."

Home Security Systems questions, answered by experts

Keyless locks are great for convenience, letting you unlock doors with a code or your phone so you don't need to carry keys around. They also often come with helpful features like temporary codes for guests. On the downside, they can be more costly up front and do require batteries that will eventually need replacing. If you value ease of use and additional security features, keyless locks are worth the investment.

Insurance companies weigh the amount of potential liabilities on your property to increase (or decrease) the cost of your home insurance. They will use several factors to decide if there are more chances for peril or injury to take place at your home. These factors include your location (whether you live in an area with high risk for natural disasters), the age and condition of your home, and whether you have any “attractive nuisances”—features that both increase the aesthetic of your home and potential for injury—like a pool or treehouse. 

In general, keyless door locks are considered safe. They can’t be picked like a traditional lock, and unless a thief can guess your code, it’s pretty tricky to break into a house with a keyless door lock. But that doesn’t mean they come without risk. 

When asking yourself, "Are keyless door locks safe?” consider the style of the system. Hackers could potentially break in if it operates on Wi-Fi, but it’d take some time and effort. You’re also at risk for a power outage, depending on the type of lock. That being said, there are no more risks associated with keyless door locks than a traditional lock.

A deadbolt is one of the most secure locks you can install on your front door, so it is better in terms of home security than other types of locks. While deadbolts are typically more expensive than a regular lock, they’re still quite cost-effective and provide an additional layer of security that may even deter some intruders.

Yes, you should always change your locks after buying a house. Do so as soon as possible after you move in. Otherwise, you won’t know who has working keys to the property, whether they’re spare keys or otherwise. If an intruder gains access to your house with a key, it may not be covered under your homeowners insurance.

By submitting this question, I acknowledge and agree that Angi may publicly display my name, city, state, and question on the website for professionals and others to see.
