"I would like to recognize employee Doug A at SafeStreet/ADT. We’ve had an old security system sitting in our house for over 15 years without service or functionality. He took the time to explain the differences between how the old systems work and how the new systems work. He was patient with us, and we are happy customers."

"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."

Locksmiths FAQs, answered by experts

Most jobs take 30 minutes to 2 hours, but high-security systems or multiple lock installations may require additional time.

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

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.

Smart door locks are safe to use and are usually considered safer than traditional locks with keys. While all electronic devices can be hacked, that doesn’t happen nearly as frequently in real life as people may think. You can also invest in multiple locks of different types for enhanced security so you don’t rely solely on one smart lock.
