"We had an exterior door to our garage that would not close/latch properly and therefore presented a security risk. I called multiple companies for quotes and explained we'd like to try repairing the door first, but are open to replacing it if necessary. Multiple other companies told us there was no other option but to replace the door. Robert's company was the last one on our list to gather a quote from. He came by the very next day after I called, immediately found core problem with the door (simple loose screws in the hinges) and fixed then and there. The fix was so simple, he didn't even charge us. I so appreciate that Robert wasn't trying to scam us into a bigger more expensive project of replacing the entire door. He is honest and quickly finds the root of the problem. We will be hiring Robert's company exclusively moving forward for our various projects around the house. Feeling so lucky to have found him! Thanks so much, Robert!"

"I called Alarm Protection Group AFTER my office was burglarized. Now I feel SAFE. William is great to work with. He's neat and tidy, prompt, presentable - not a butt-crack type of guy, and he doesn't leave a mess in his wake. He's also knowledgeable about the equipment and only uses high-quality products."

"ADT is the best company 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."

Locksmiths questions, answered by experts

If your door handle turns without opening, the most likely culprit is a loose or stripped spindle. This part connects the handles to the latch mechanism, and when it’s not properly engaged, turning the handle does nothing. Other issues might include a broken latch, loose screws, or even something small blocking an inner mechanism. In any case, it’s usually a matter of tightening, adjusting, or replacing a worn-out part inside the handle assembly—or calling in a professional to do it for you.

Newer, electric-powered door locks generally have a life span of five years or less. That’s thanks, in large part, to a phenomenon called planned obsolescence, in which products are programmed to need replacing after a certain amount of time. That’s also why older, manual, push-key locksets can last up to 30 years with regular cleanings and maintenance. When it does come time for a new set-up, know that the cost to change locks ranges from $130 to $500 on average.

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.

Lock picking is a relatively subtle method of unauthorized access, making it hard to detect. But there are telltale signs to look for. First, look for scratches or tool marks around the keyhole or the lock's surface. Also, check for loose or misaligned components, like a wonky strike plate, which could indicate tampering. Consulting a locksmith or security professional for an assessment can provide valuable insights, too. Investing in high-quality locks and considering additional security measures, like security cameras, can help deter potential intruders and enhance your overall safety.

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.
