Home Security Systems questions, answered by experts

You don’t need to completely revamp your security system constantly, but it’s a great idea to give it a once-over every year. Look for potential upgrades or new features—like smart home tech or replacing outdated equipment—that could boost your safety. If you make any significant changes, let your insurer know as they may adjust your discounts to reflect your improved security. Staying on top of your security not only keeps your home safe but ensures you’re getting the best possible rate on your insurance.

Faulty sensors, weak signals, false alarms, and control panel malfunctions are common problems requiring repair.

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.

Yes, a home security system can be worth it for your peace of mind alone, but it can also save you up to 20% on your home insurance. The insurance savings will help defray the initial setup costs and subscription costs over time. Locations with higher crime rates also make home security systems a valuable investment, but it ultimately depends on your personal preferences and asset values.

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.
