"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

Several types of deadbolts are available, including single-cylinder, double-cylinder, rim, smart, and electronic deadbolt locks. The most common type found in U.S. homes is the single-cylinder deadbolt, which uses a key on the exterior and a thumb turn on the interior. A double-cylinder deadbolt features two locking mechanisms and requires a key to be operated from both the inside and the outside.

There are several ways to add security to a sliding glass door. To start, install a rod or deadbolt lock instead of the flip-lock that comes standard with most sliding glass doors. Add a sensor to the door and monitor any activity through your home security system.

Finally, installing shatterproof window film will help keep the structural integrity of the glass if it cracks.

Most jobs take 30 minutes to 2 hours, but high-security systems or multiple lock installations may require additional time.

It is best to use a dry lubricant, such as a Teflon-based option, for door locks. Unlike popular oil-based lubricants, dry lubricants leave a non-stick, water-repellent coating that does not attract dust, dirt, and other debris. Using an oil-based lubricant can cause these particles to build up inside the lock, making it difficult to operate or even damaging the internal mechanism. You can find dry lubricants, some of which are made specifically for locks, at most hardware stores.

Regrettably, entirely pick-proof locks don't exist unless you opt for keyless varieties. Locks advertised as "pick-proof" are, in reality, more resilient against lock-picking and bumping attempts because of complex mechanisms consisting of pins and sidebars. These locks work like this—they assign two tasks to the key, enhancing security by making unauthorized entry more challenging.
