"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."

"Judy was excellent and A+ communication. She responded very quickly and we were able to text pictures and get options and a quote. She came promptly when she said, very professional, and extremely knowledgable. New set works great. Will definitely use again for locks."

"Locksmith, John, left keys on dash after recoding ignition and allowed car to lock…. Insisted that we (body shop) locked our own keys in the car and refused to apologize or own up to the mistake… Very poor customer service. Told us to get our own lock out kit to get the keys out… Recoded another vehicle for us…. Also left keys on dashboard and didn’t say anything, keys were left overnight in the car unlocked in a non-gated car lot …. Luckily not stolen!!! Never knew a locksmith who would leave keys in an unoccupied car…."

FAQs for locksmith service projects in Brookhaven, PA

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.
