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."

"Darrin fixed an increasingly problematic front door mortise lock. Works swell now; it was a toughie. He also fixed two other outside door locks that had been iffy. Prior repairman who had installed the locks and doors didn't do a great job. Now we have working and locking doors. Spiffy. I thought the price was very reasonable. He was professional and knowledgeable. Will hire him again for any lock issues. I wish I had done this over a year ago instead of dreading it (afraid we would have to replace the locks or doors)."

"DO NOT USE THEM!!! First they required a credit card to come out then they came out and spent an hour attempting to rekey my lock but couldn't then charged me $150 for doing nothing because they claim the lock was damaged. They gave me a quote to replace the Anderson lock for an absurd amount like thousands of dollars. Then I had another locksmith replace the cylinder in less than an hour and it was all done. I requested a refund and they refused so I disputed with my credit card and Reeds had the audacity to call me to tell me llied and asked me if how I could sleep at night. I asked him how he could sleep at night because I told the truth and they tried to scam me. They are highly unethical!"

Prolocksmiths-24/7 value honesty and integrity in all aspects of our business. We offer a variety of locksmith services that are customizable to each individual project. We specialize in home, business, and auto locksmith services. We pride ourselves on the quality of our work as well as our commitment to outstanding results. We look forward to building lasting relationships with our clients and guarantee your satisfaction!

"When I called Prolocksmith I got a dispatch person who seemed to be working from home. She was quick in trying to connect me with someone to do the work. Referred me to discuss rate and other specifics with the locksmith who would be performing the work. The actual locksmith called me within 5 minutes and indicated that he would be at my place in 20 minutes. I had to interrupt him to tell him what type of lock was on my door. Also when I asked about rates, he said that he would not be able to tell until he was there and I could opt out at that time. Locksmith who showed up was with another company and did not know anything about Angieslist. He tried to give me some sort of a discount but said the software on his smartphone would not let him. Upside, he arrived within 30 minutes. Downside, cost $272 and I am not sure what company opened my door but it was not the licensed Prolocksmiths."

There is no job too challenging or too small. I pride myself on two things: 1) quality of my craftsmanship and 2) honesty, so there are no surprises. All procedures, options and pricing will be discussed and agreed upon before any service is done. I started building my locksmith experience in 1998 and I established my own business in 2004 to do the right thing for customers who need help with this type of service. Corriea Lock and Key Mobile Unit is fully licensed, bonded and insured.

"FANTASTIC! First of all, Frederick was really responsive to our initial request, and very very patient with our questions and concerns about installing an automated lock. He explained what we needed, how to order it, and how to measure the door frame. When he came to the house, he was thorough and careful, and explained everything we needed to do to make sure the lock worked properly. He then fixed the front door lock and made an extra key on the spot. He swept the little bit of dust there was (I could not see any), and was very thoughtful about everything. I would recommend him a 1000 times over to anyone!"

Locksmiths questions, answered by experts

Always consider security a top priority in your home. Perform a safety inspection of your home. Look for broken locks and rusty deadbolts, and take an inventory of who has access to your keys.

Consider the locks on your shed, safe, and other household items. Professional locksmiths can help you determine the best safety and security options for your home and feel at ease.

When a locksmith comes to your home, ensure your safety by having the locksmith show identification and provide an itemized invoice that you can reference later.

Yes, you should change the locks as soon as you can after completing the purchase of a house. This is a matter of privacy and security, as you have no idea how many copies of the keys the previous owner made. You can change the locks yourself or hire a pro to replace or rekey the lock, which costs $50 to $100.

When the temps drop, sometimes you need to thaw a lock to regain access. Options include warming the key with warm water, applying a de-icing spray, or using a hair dryer on low heat. Avoid using boiling water to prevent damage. To prevent future freezing, consider installing a cover or shield over the lock to keep water and ice out. Remember to be patient and gentle during thawing to avoid damaging the lock or key. If all else fails, consult a professional locksmith.

If part of the key is protruding out of the lock, you can use a pair of needle-nosed pliers or tweezers to gently turn the key in the lock to open the door. If the key is fully inserted into the lock, you may also be able to use a key extractor to help turn the key into the unlocked position. 

But if the key breaks off halfway into the lock or you simply can’t reach it to help engage the unlocking mechanisms, you should probably call a professional.

First thing first: Make sure you’re using the right key. If it’s the correct key for your lock, there are a few reasons why it may not be working, like the key is worn out or the lock is jammed. Try lubricating the lock and pushing the door closed to ensure the mechanisms work correctly. If you’re still locked out, call in for help.
