"I manage a triple-decker in Savin Hill and the main entry buzzer door was completely shot. Ray came out, installed a heavy-duty auto-latching deadlatch, and fixed the strike plate. The building is finally secure again. Excellent work."

"Locked myself out of my car near Fields Corner station after a long shift. Called City Locksmith and Ray arrived in 20 minutes. He was fast, professional, and didn't charge me an arm and a leg. Highly recommended for anyone in Dot."

Triple-Decker & Multi-Family Security

Securing shared entryways is our specialty. If the front buzzer door on your Ashmont triple-decker does not latch properly, the entire building is vulnerable. We repair faulty buzzer hardware, align sagging historic doors, and install commercial-grade auto-locking deadlatches. If you manage multiple units, we can also implement a scalable master key system for streamlined access.

Residential Rekeying & Hardware Upgrades

Whether you just bought a renovated home near Savin Hill or a condo in Codman Square, making sure you control the keys is critical. We provide comprehensive residential rekeying. By swapping the internal pins of your existing deadbolts, we instantly lock out any previous owners, realtors, or contractors. We can also upgrade aging, builder-grade locks to high-security ANSI Grade 1 deadbolts to prevent kick-ins.
