Alexius Security Lock & Key has served the Metro Denver area with honest, affordable locksmith services for over 16 years. Our staff is highly-trained, professional and courteous. Our business is bonded and insured and our products and services are guaranteed.

"What a pleasure to find this company. We had replaced an exterior door but the door installer had not been able to properly place the deadbolt. I called Alexius and was scheduled for a service call the next day. Martin Molina confirmed our appointment beforehand and arrived on time. He was professional and courteous, and quickly diagnosed the problem—the deadbolt was too small for the opening in the door. The hardware was replaced, carefully aligned, and tested. In addition, Martin checked and fixed another lock set that was sticking, and took our old hardware to be recycled. Highly recommend."

Protecting homes and businesses since 1950, Guardian Protection is one of the nation's largest and most highly regarded security companies. We provide smart technology, 24/7 professional monitoring, and peace of mind to hundreds of thousands of customers. Our products are installed by experts, monitored by real people, and truly make a difference. We do what we do because of one simple truth: life is better when it's safe.

"We hired Guardian to install our security system at our Washington, DC, business. The service and quality of the work was horrible. We had cameras and an alarm system installed; it was a relatively large system. They outsource most of the work to various vendors. They could not manage their vendors; what was supposed to take a week took two months. The sales rep did not return calls, and you could never get anyone in management on the phone. Random people would show up at unannounced times. The few things that an actual Guardian employee did were they made a huge mess of our newly remodeled office and were rude to our staff. We have offices in five markets across the US and have high security at each; we have never had such a poor experience."

"I explored several lock companies to change over the hardware on my 10 exterior doors in my home. The companies all refused to make an in-person visit and instead wanted me to send them pics of all of my doors. I was given the name of Southwest Lock and Safe and to my delight, they wanted to send out an expert (Chris Loveall) to see the project and give me an estimate. When I wanted to ensure that the style and color of the hardware was correct, Shea (the owner) sent out Triston to bring me samples. Chris and Triston then came out and did a GREAT job installing all the hardware and locks. And, due to COVID-19, they wore masks that covered both their nose and mouth. I am SO grateful for this company’s fabulous customer service and a job well done! THANK YOU"

We are a full service HVAC company serving Northern Colorado. We have NATE certified technicians. We are a Carrier Factory Authorized Dealer (CFAD). We realize that problems don't just happen from 9 to 5 and that's why we have 24 hour emergency service.

"Beware!! They quoted me one price but once they got there and I called their office the lady said it would be more. Then after multiple calls while they kept changing their story they refused to give me my full deposit back until they received a refund for the permit. I will absolutely never use this company. It was the biggest headache ever."

Locksmiths questions, answered by experts

The most secure lock for a front door is typically a deadbolt. There are many types of deadbolts to choose from, the most basic of which is the standard single-cylinder deadbolt. This is the lock you find installed on most front doors. For added security, you could go with a double-cylinder deadbolt, which requires a key to operate the lock from both the outside and the inside. 

There are many types of deadbolts, but these tips work on most. First, address any grime buildup. A bit of WD-40 will loose up rust and dirt so the deadbolt can turn. Inspect the door and frame alignment if this doesn't resolve the issue. Adjust the strike plate or the deadbolt's position to improve alignment. If the problem persists, disassemble the lock to inspect for damaged or worn parts. If you are unsure how to do it, hire a local locksmith.

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.

It’s possible, but depends on the design of your lock. Some door locks that lack a keyhole do boast a small hole on the exterior handle or knob. This hole’s primary function is to allow water to drain out of the lock, in addition to giving homeowners an easy spot to insert lubrication. However, you can typically use a paperclip in this pinhole to unlock the door by manipulating the mechanism inside. 

Locksmiths offer keyless entry systems, high-security locks, panic bars, electronic access control, and biometric security solutions.
