"I contacted Doorbusters Lock & Key for rekeying several locks at my home, and they were excellent from start to finish. The technician arrived quickly, was professional and polite, and rekeyed everything perfectly. All the locks work smoothly, and the price was fair and exactly as quoted. I really appreciate how efficient and honest they were, definitely a company I’ll call again for any locksmith needs. Highly recommended!"

"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."

"We have had a malfunctioning mini split that we could not find a technician for, after multiple failed attempts. Vintage Home Services was prompt in responding and scheduling, diagnosed our issue, and repaired for a fair price. Would highly recommend."

"This was a great experience! Zach from Surface Experts was wonderful from start to finish. I just started talking with him last week. And today (about a week later the job is done. And done beautifully! Zach made an appointment for today for between 8 am-11am. Keith the service technician texted me when he was on his way. He was very nice and professional and did an amazing job!! He was done in about 1 hr. He even tightened a screw on one of my chair legs that had loosened. All in all a great experience!! I would definitely recommend them to anyone needed something done! And I would use them again!"

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.

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.

Yes, as long as it’s thick enough for the deadbolt. Most interior hollow core doors are at least 1 1/2-inches thick, which is usually the minimum requirement for a deadbolt. You’ll want to find the lock block first before installing. Also, most hollow doors require additional reinforcement for locks, such as a reinforcement plate or plywood block.

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.
