"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."

"It is so important to find an honest, trustworthy locksmith and Alan is definitely the best in the business. He is a total professional and I trust him to re-key my whole house. I have used him on numerous occasions - basically whenever anything goes wrong with my locks- and have recommended him to colleagues and friends. All have had equally positive experiences with both quality of work and price. I would not believe that other reviewer."

"Arrived 2 hours outside 3 hour window, but did at least call to say they'd be late. Low-tech vent cleaning: a drill, a wire brush, and extension cable, two guys in a car, a short ladder, a small vacuum cleaner. I've had an entire house's vents steam cleaned before at the price they charged for 20 feet of dryer duct. Too expensive for the job and amount of effort put in. The invoice said Locksmith so obviously they do this on the side. The job was passable, just not super thorough. Not recommended."

"What a gem I found in Gil, he is the absolute best!! He replaced the deadbolt on the front screen door, and my back screen door had a broken slide latch, that he also repaired. I had one other problem with a gate latch that needed to be ground down, and he repaired that also! Gil is professional, friendly and a pleasure to be with, I will definitely call him again if I have another problem with any locks. Also his prices are very reasonable, and he takes his time and does an excellent job."

"When I called to make appointment, I was told coupon was just to show up, but no work was included. The price quoted for the replacement car door key was higher than I had paid another locksmith in the past for mobile services. I'm not sure of the date, but it was when the coupon ran earlier this year.

Locksmiths FAQs, answered by experts

Deadbolts are solid and durable as can be, but the pin and tumbler can still be forced open, thus making this type of lock susceptible to picking. Most types of deadbolts are harder to pick than a traditional spring-based lock, though. It requires a specialized lock pick and a tension wrench to align all of the pins, thus unlocking the door. 

Yes, you should always change your locks after buying a house. Do so as soon as possible after you move in. Otherwise, you won’t know who has working keys to the property, whether they’re spare keys or otherwise. If an intruder gains access to your house with a key, it may not be covered under your homeowners insurance.

The cost-effectiveness of fixing or replacing a door lock depends on the severity of the issue. Repairing a minor problem, such as loose screws or a need for lubrication, is usually cheaper than replacing the entire lock. However, replacing the lock if it is severely damaged, outdated, or lacks security features may be a better long-term investment. New locks often have improved security features, enhancing your property's safety.

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.

In some cases this is possible, but it’s not advisable as the screwdriver is likely to leave marks all over the wall and a noticeable dent on the door. Move slowly and carefully if you have to use this method, and consider calling an emergency locksmith right away instead of trying to break in.
