"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."

Home Security Systems questions, answered by experts

Depending on your needs and wants, investing in a security door can be well worth the cost. Now that you know the pros and cons, you can decide if it’s a purchase that makes sense for your family. If you’re ready to have one installed in your home, look into security door installers in your area.

Yes, keyless locks can be quite safe, but their security depends on the type and quality of the lock you choose. Many keyless locks offer added features like biometric access, PIN codes, and smartphone connectivity, making them potentially more secure than traditional locks. However, keyless locks can also be susceptible to hacking, battery failure, or technical malfunctions, so it's important to choose a reliable brand and stay on top of software updates and maintenance.

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.

Home automation costs an average of $1,000, and most projects fall between $200 and $2,000. The total cost will depend largely on the level of automation you want in your home. High-tech, all-inclusive systems can cost well over $10,000 for larger homes, so most homeowners set a budget and then provide that to an expert to get the best results. You can also opt for DIY home automation technology for between $100 and $500, but the scope and interaction between products are usually limited.

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.
