"Bought security through ADT mainly for the automation options that come with the system. My spouse loves being able to turn on and off our lights in different areas of the house while we are gone. We travel often, so giving the illusion that we are home is a good deterrent."

"This was the third company we contacted after having no follow through with the first two. I explained to Ramiro of Northbay Technology what our problem was. He had a technician here in a few days, he fixed the problem as well as giving us useful feedback on our system. Our streaming and dvd system work after not having it for almost 3 months! Ramiro also called afterwards to make sure everything was still working. What a treat to find a quality company that does what they say they’ll do and also offer great customer service."

Home Security Systems questions, answered by experts

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.

You'll likely need more than great home staging to sell your home. Now is a great time to get to work on the curb appeal of your home . Hire local exterior painters and landscapers to coat the exterior of your home and bring it new life with some sprucing up.

The average cost of a home security system is about $700, ranging from $280 to $1,150. Costs to consider include equipment, surveillance fees, and other additional features. Cost factors that determine your system’s price include the type of security system, materials, labor, activation fees, monthly fees, and permits. Additional features and upgrades may include:

  • Video surveillance monitoring: $40–$65 per month

  • Smart home locks: $150

  • Smart home lighting: $15–$90

  • Smart smoke, fire, and carbon monoxide alarms: $35–$100

  • Smart thermostat: $130–$500

You likely can reset your house alarm without the code, but it depends on many factors like how it’s wired and whether or not there’s a default reset code. Most companies make bypassing a security alarm without entering your code challenging to prevent burglars from simply resetting the alarm during a break-in. Your best bet is to contact your alarm company directly to get specialized support for your situation. 

But, while you wait for support, you can disconnect it from the power source to stop the alarm from going off.

Find a vetted and trusted locksmith to work on your home so you can feel comfortable and safe. Hire a professional with these qualifications:

  • Search a verified directory of locksmiths near you, like those on Angi. 

  • Check for an Associated Locksmiths of America (ALOA) logo on their website or company logo.

  • Read company reviews. You can also check their social media pages.

  • Ask for a pro’s credentials, insurance, licensure, and customer testimonials. 

  • Check if the locksmith is knowledgeable about various topics, from decorative locks to the newest technologies on the market.
