"It was a job made more complicated by the age of the doors/locks being replaced. The front door was modified to fit a modern lock and an old deadbolt was replaced on the back that was significantly easier. It was handled with professionalism and aplomb. "

"We were not locked out, but our key only worked with great difficulty. We called late Saturday night and he came on Sunday. No one else answered the phone or even called me back. He answered the phone late Saturday night and made an appointment the next day. He replaced our lock. Sunny was kind and efficient. His tech couldn't make it, so he came himself. He was very polite and easy to work with. Sunny is a hero!"

"The guy arrived on time ready to do the job. He was very efficient went over with me. The problems that I was having with my door and step-by-step. Show me what he needed to do to fix the power he replaced the parts that needed to be replaced and all of this did not take no more than an hour and a half. I am very happy with his work and I will be calling them out again for future services."

"We hired Guardian to install our security system at our Washington, DC, business. The service and quality of the work was horrible. We had cameras and an alarm system installed; it was a relatively large system. They outsource most of the work to various vendors. They could not manage their vendors; what was supposed to take a week took two months. The sales rep did not return calls, and you could never get anyone in management on the phone. Random people would show up at unannounced times. The few things that an actual Guardian employee did were they made a huge mess of our newly remodeled office and were rude to our staff. We have offices in five markets across the US and have high security at each; we have never had such a poor experience."

"Joe arrived within an hour after I called him to fix my lock. It was such a relief as it was a front door deadbolt. He did a great job and was personable. Joe needed to come back to fix another lock and called to confirm when he would arrive. This is exactly what I look for-- someone who does a good job, is responsive and reliable. He was reasonably priced, too! Would definitely recommend and hire again!"

FAQs for locksmith service projects in Union, NJ

The installation timeframe varies based on door preparation and lock complexity. For doors already prepared with appropriate holes, installation might take 15 to 30 minutes. New installations requiring drilling take one to two hours. First-time DIY installers should allocate additional time to ensure proper alignment and function. Professional locksmiths complete standard installations efficiently due to their specialized tools and experience.

Most residential doors can accommodate deadbolts, but certain door types present challenges. Solid wood and fiberglass doors accept standard deadbolt hardware, while metal doors require specialized drilling equipment. Hollow-core interior doors lack the structural integrity to properly support deadbolts without additional reinforcement. Doors should be at least 1⅜ inches thick to properly house standard deadbolt mechanisms.

Door warranties remain valid when deadbolts are installed according to the manufacturer's guidelines. However, improper installation that damages the door structure might affect warranty coverage. 

Before modifying any door under warranty, review the documentation for specific limitations or requirements regarding hardware installation. Some manufacturers provide templates or guidelines for acceptable lock placement to maintain warranty protection.

Rekeying offers a more economical alternative to complete replacement when you need to change access, but the lock mechanism remains in good condition. This process involves reconfiguring the internal pins to work with a new key while retaining the existing hardware. For homeowners with multiple locks, rekeying provides the convenience of using a single key for all entry points while maintaining security.
