"I could not have asked for a better experience. Staff at Mr. Handyman are truly professionals! Appointments were confirmed daily, technicians arrived on time, cleaned entire work area daily, communicated the progress of the project daily. I have used other companies in the past and there is no comparison. I will certainly be using them again for my next project and have recommend them to my family or friends."

"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."

"Despite a hiccup with scheduling, AA Lock & Key was professional, cost-efficient, and great to do business with. I had the pleasure of working with the owner, who even went above and beyond the call of duty by helping me a door that was jamming when we tried to close it. He kept me abreast of everything he was doing, made me test his work while he was there, and all-in-all proved that the hiring of AA Lock & Key was a good decision. Should we need a locksmith in the future, I will be hiring them."

Locksmiths questions, answered by experts

Security experts recommend deadbolt locks as the most secure option for a house's exterior or entry doors. Deadbolts provide the best security because they can prevent most types of forced entry and are harder to lockpick. Common types include the standard single-cylinder deadbolt, which is often found on front doors. For enhanced security, you can opt for a double-cylinder deadbolt, which requires a key to operate from both the inside and the outside.

Many local hardware stores have the equipment to copy basic keys at a low cost. Some locations may have freestanding machines where you can pick out a blank and insert it and your original key into the duplicating machine.

The easiest way to pick a lock is by using a titanium rake pick. This type of lock pick comes in a variety of shapes used to simulate different key configurations but generally has a tip with a bent design. Rake picks are the most beginner-friendly lockpicks and the simplest to learn how to use.

Locksmiths offer keyless entry systems, high-security locks, panic bars, electronic access control, and biometric security solutions.

Yes, locksmiths can design and install master key systems that grant different levels of access to various employees while maintaining overall security.
