"Walter and Glen at Protect Your Home Group with ADT are the best people 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."

"I had a bit of trouble with my molding around the doors vs how the system was designed. The tech guy hung with me for 39 minutes until it was perfect. I called customer service a couple times after that with questions that came up. The customer service team are professional and knowledgeable."

"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.

"Timely, clean, perfect job. Dave is a true professional and couldn't be better. Not only did he come after hours so I didn't have to miss work for the bid, but quickly got his crew In and had the job done days before expected. The work is exceptional with clean lines. I would highly recommend him."

"Willie's and his crew did an excellent job and all were very hard workers. I highly recommend poured concrete in a crawl space to seal out the musty smell and dampness."

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.

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.

Rekeying a lock changes the internal mechanism so that a new key works, while replacing a lock involves swapping out the entire hardware. Rekeying is a good, cost-effective option when you want to ensure old keys no longer work, such as after moving into a new home or losing a key. It's also ideal if you want to keep your existing lock hardware. You should opt to replace the locks entirely if you want to upgrade to a more secure or different style of lock, if the current lock is old or damaged, after a break-in, or if too many copies of the old key exist.

Security experts recommend deadbolt locks as the most secure option for a house's exterior or entry doors. Deadbolts provide the best security because they can prevent most types of forced entry and are harder to lockpick. Common types include the standard single-cylinder deadbolt, which is often found on front doors. For enhanced security, you can opt for a double-cylinder deadbolt, which requires a key to operate from both the inside and the outside.

It can affect security, especially if you don’t finish it properly. A Dutch door has more moving parts that can be compromised, so you’ll want to use solid hardware and make sure everything lines up and locks cleanly. If the latch is flimsy or the two halves don’t sit tight, it’s going to be easier to force open.
