"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.

"I switched from another company to Security One, they use the same equipment. They had to come out and recode everything. I simply switched because of the financial benefit. I have only had them for a few months, and I haven't had any problems with them. They save me some money every month.  When my alarm went off, they did call me."

"A Plus Doors is a great name for this company, because A Plus service is what we received. Within seconds of submitting my request to ServiceMagic, Mark called.

We will definitely be contacting him for future needs, and recommending his services as well!"

Locksmiths questions, answered by experts

If you don’t have your original key, the easiest way to obtain a copy is to call a locksmith. For house keys, your locksmith has several options for configuring a new key: 

  • They can input a lock’s identification code into a database to obtain key-cutting instructions.

  • They could analyze the lock cylinder to determine how to cut a new key.

  • They can create an impression of the lock cylinder from which to cut a new key. 

Yes. Most deadbolts purchased from a home improvement store include a step-by-step installation template that is easy to follow, even for novice DIYers. One of the most important steps for successful deadbolt installation is having the proper tools to start with and carefully measuring prior to any attempts at installation.

Yes, many locksmiths offer 24/7 emergency services for business lockouts, broken keys, and security breaches.

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.

Costs depend on lock type, service complexity, labor, emergency availability, and whether security system integration is needed.
