Zee locksmith is specialized in all types of locks for your home doors, windows, closets, safes. Zee locksmith installs and repair locks and keys. If you lost keys, want to re-key, make new key, break or open any lock just let us know.

"The person who showed up at my house was awesome, but it wasn't Zee's locksmith. It was Metro Locksmith. That is fine, but that wasn't communicated with us. Also they indicated they would be at our house in an hour, but it took over 2 hours. Again, I would highly recommend Metro Locksmith since they were the ones who actually did the work, not Zee's. I gave 4 starts because I didn't want a negative review to affect Metro, but I was annoyed by the lack of communication by Zee's."

GGD was founded as a local, family-owned business in 1988 by Peter Giglio, Sr. as a solo Technician out of his home. We grew. Providing superior customer service with values of Honesty & Integrity, our dedicated, experienced crews began additional service for Fairfax County homes in 1991. As our reputation for dependability spread, our 10 trucks & 15 employees outgrew the original Gaithersburg location in 2019 as we moved to a more spacious Rockville location. Peter’s son, Pete Giglio, Jr., succeeding his Dad, and long-time Operations Manager, Ryan Smart continue today to guide Gaithersburg & Fairfax Garage Door to satisfy the needs of DMV homeowners.

"Everything went fantastic Anthony was my technician, he was courteous, performed the job efficiently, did a great cleanup job of any materials in my garage. Explained exactly what was done and the future work that I needed to be done! I requested him to do the follow up work! The company itself is also great. They did follow ups via text and email; responded to everything quickly and were able to accommodate my schedule. I will continue to use them as a company."

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."

Locksmiths questions, answered by experts

When you take a key to a hardware store or a locksmith for copying, you can expect the key-cutting process to take as little as 30 seconds. The key copier will review your current key to decide on the correct blank. Then, your original key and the blank are inserted into a key duplication machine to cut an exact key copy. When it’s all said and done, you can have a new key in your hand in just a couple of minutes.

Expect to pay between $50 to $200 if you hire a locksmith to change your locks. That figure includes labor and the cost of basic hardware. The cost will naturally be higher if you plan to install more expensive locks, like smart locks, and if you need a lot of them.

Homeowners can save money by replacing locks themselves. A typical rekeying kit costs about $10 to $25. The only additional cost is purchasing new house keys, and those are no more than a few dollars per key. If you want to replace the locks on your own completely, the main cost is the price of the locks themselves. A standard knob-style lock starts around $25, while electronic locks and smart locks will run in the hundreds of dollars. The only additional tools you should need are a tape measure, screwdriver, and screws if they are not already provided.

Lock bumping is a technique locksmiths use to quickly and quietly open a pin tumbler lock, typically found in most types of deadbolts. It involves inserting a specially crafted key, or bump key, into the lock and tapping or "bumping" it with a mallet or similar tool. The force applied causes the lock's pins to jump momentarily, allowing the lock to be turned and opened. Unfortunately, thieves also use this technique to break into homes. Luckily, products like a deadbolt strap will fortify your lock.

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.

If you’re having an issue turning the key inside a lock, chances are there is dust or dirt buildup within the cylinder. The easiest solution is applying a dry lubricant to the lock, which loosens the dirt buildup. You may need to turn the key a few times for it to work properly again.
