"I called Alarm Protection Group AFTER my office was burglarized. Now I feel SAFE. William is great to work with. He's neat and tidy, prompt, presentable - not a butt-crack type of guy, and he doesn't leave a mess in his wake. He's also knowledgeable about the equipment and only uses high-quality products."

"ADT is the best company to talk to in terms of security alarm. Being a locksmith myself I know how important it is to deal with the right people. I referred a lot of customers to them and so far they are happy with their service. I myself got one for my house. Thank you for a consistent service and great deal."

"Super locksmith, made me feel at ease the moment I talked to him on the phone. When other places said they were going to have to drill out my car's trunk lock I was worried, Lockstar took the time to go through the rear seats of my car and to unlock the trunk that way. After opening the trunk, Lockstar showed me how to replace the broken trunk release myself and how to open the trunk again if I need to. He saved me money and time, which is much appreciated."

"I communicated with Rob Calbo for services of a background check with CSI Secure Solutions and he was fantastic.
He spoke with me in a very professional manner and put me at ease right away.
The process was seamless and my request was delivered very efficiently. Within just a few hours of providing them with information, I was able to get feedback. Rob took the time to speak with me and answered all of my questions. 
I will definitely be using them again in the future should the need arise, and I would definitely recommend them as being very efficient, professional and reliable.

Locksmiths questions, answered by experts

Using a combination of tools (often store-bought plumbing tools) and brute force, a burglar can easily snap the lock on a door. Snapping a lock aims to gain access to the cylinder inside, which holds the locking mechanism. Once the thief snaps the lock, they can pick the cylinder open and walk right in.

Smart door locks are safe to use and are usually considered safer than traditional locks with keys. While all electronic devices can be hacked, that doesn’t happen nearly as frequently in real life as people may think. You can also invest in multiple locks of different types for enhanced security so you don’t rely solely on one smart lock.

Yes, as long as it’s thick enough for the deadbolt. Most interior hollow core doors are at least 1 1/2-inches thick, which is usually the minimum requirement for a deadbolt. You’ll want to find the lock block first before installing. Also, most hollow doors require additional reinforcement for locks, such as a reinforcement plate or plywood block.

There are several situations when you should change or replace your locks to ensure your home's security. Key moments include moving into a new house, after a break-in or attempted break-in, or when a roommate or anyone else with a key moves out. It is also wise to change your locks if you lose your keys, especially if they have an address attached or you suspect they were stolen. Finally, if your locks are old, broken, worn out, or have become unreliable, they should be replaced.

Smart locks offer a similar level of safety to traditional or conventional locks because they often use comparable locking mechanisms, such as deadbolts. The primary difference is the access method: smart locks use a login or code instead of a physical key, which adds convenience. While not inherently safer, some smart locks have added security features that can deter intruders, like shutting down after too many incorrect code attempts or being harder to pick. For the best security, it's recommended to combine any lock with other home safety features like motion-activated lighting, security cameras, and window and door sensors.
