Professional Security Upgrades & Lockouts in Brookline

Brookline demands a higher standard of residential security. With its mix of grand historic homes, luxury condominiums, and bustling commercial strips, cookie-cutter locksmith solutions simply do not work here. City Locksmith 24/7 provides master-level craftsmanship tailored to Brookline’s unique architecture.

"I work for Joy At Home, LLC, a Homecare service company that takes care of elderly people and I had a customer in Brookline, who needs our services and our company is taking over his care. Ray from City Locksmith was called in yesterday (9/19/26) because there is a built-in lock on our clients’ door that had to be changed out/re-keyed It is an interconnected lock, meaning that the latch and deadbolt are interconnected Quite technical. Ray showed up on time and kept in communication with me which I appreciate. He re-keyed the cylinder so that we had new keys to walk and unlock this interconnected door knob deadbolt combination that I believe was built in the 1950s may be early 60s. He showed me his work and the cylinder he had to read. It was a mess from a previous lockout with my client about 15 years ago and the locksmith made a mess of the job at that time. Ray rekeyed it to perfection and cut me seven keys that work perfectly. I watched him reassemble the door which had issues and he took about 40 minutes to reconnect everything and it came out to perfection. The guy is a pro, highly recommend and he explains things very well so I was in the loop on all the work he was doing. I will use him in my profession whenever we need a locksmith because what he showed me yesterday convinced me he’s the guy."

"Ray showed up on time and was in good communication with me. Heavy duty lever lock was rekeyed since we were lacking key as Ray the locksmith out of Brookline from City Locksmith suggested that we start Fresh by opening lever lock cylinder & rekeying it to a new set of keys. Watched him breakdown & carefully re assemble the lever handle. Ray showed me all the parts and the weight of it and told me it was a very good quality heavy grade commercial Lever lock that was definitely worth keeping as it would last indefinitely. The work was very professionally done with clear explanation at a fair price. I would definitely use him again and highly recommend"

"I got locked out of my apartment in Brookline on a holiday weekend. City Locksmith immediately picked up my call, and said they would be there in 10 minutes. He arrived early, and got me in my apartment in no time with no damage to the door. Highly recommend!!"

"Found him on ChatGPT this morning because my front door knob did not work and the door did not close, ChatGPT explained to me what kind of lock I had and recommended City Locksmith out of Brookline along with Yelp and Google. I called Ray from City Locksmith and expected to wait cause it's Sunday. However, he said he said he would be out in 30 minutes which I doubted it and I'm fact he arrived in 30 mins. He not only fixed it but also saw the paint on the whole side of the door was scraped. Ray the locksmith also found a nail at the side of the door that was blocking the closing of the door. With my permission, Ray also removed the nail and shaved the top of the door. Additionally, he noticed the latch plate on the side of the door that was sticking out and he fixed that by receding and now my door can also be closed with just 1 finger. To say the least, I'm extremely happy with ChatGPT and Ray who came out to West Roxbury and fixed my door to my satisfaction at a reasonable price."

24/7 Emergency Lockouts

Lockouts are our most common call. Whether you are locked out of an apartment in Washington Square or a historic home near Longwood, Ray provides rapid, non-destructive entry. We arrive equipped with professional lock-picking tools to get you back inside without drilling your hardware, usually arriving in under 20 minutes.

Multi-Unit Building & Intercom Security

Brookline has a dense landscape of multi-unit buildings and brownstones. Managing access control here is crucial. We diagnose, repair, and install buzzer systems, electric strikes, and intercom panels for properties across Brookline Village and Chestnut Hill to ensure building entry is both secure and seamless for tenants.

Whole-House Rekeying & Security

The Brookline real estate market moves quickly. When you close on a new property, neutralizing unauthorized keys is your first priority. We provide comprehensive residential rekeying, ensuring your front entrance, garage, and patio doors all operate on a newly cut set of keys.

Lock Installation in Brookline

Brookline's brownstones and older multi-family buildings often carry decades-old hardware that is past its reliable lifespan. When a lock cylinder is worn or the bolt no longer throws cleanly, replacing the entire unit is the right call. Our lock installation service covers everything from swapping a single entry deadbolt in Coolidge Corner to outfitting a newly converted condo building with Grade 1 hardware throughout — matched to the existing door prep so no extra carpentry is needed.

Smart Lock Assessment for Brookline Historic Doors

Older doors in Brookline Village and Longwood come in non-standard sizes and configurations that rule out many off-the-shelf smart locks. Before you order anything online, it is worth having a professional assess your door. We evaluate your existing hardware, measure the backset and bore diameter, and recommend a smart lock that fits your specific door without modification — preserving both the historic character of the entrance and the structural integrity of the frame.

Just Moved into Brookline? Rekey Your Locks First

Brookline's brownstones, older condos, and multi-family buildings have often changed hands multiple times — and with each transition, keys get duplicated and distributed. When you move into a Coolidge Corner condo or a Longwood brownstone, the previous tenant's landlord copy, the maintenance crew key, and whoever else had access are all still live until you act.

Rekeying your locks on move-in day is the single most cost-effective security step a new Brookline resident can take. We change the internal pins of your existing deadbolts — no new hardware needed — and issue you fresh keys that make every previous copy obsolete. For buildings with multiple units or shared entry, we can rekey the whole property on one visit.

Commercial Locksmith Services in Brookline

Coolidge Corner retail, Washington Square businesses, and the medical and professional offices that line Beacon Street and Harvard Street all need commercial-grade security that can withstand constant daily use. Our commercial locksmith services in Brookline cover everything from a single storefront rekeying after staff turnover to a full multi-tenant building access overhaul.

We install Medeco and Mul-T-Lock high-security cylinders that prevent unauthorized key duplication — essential for any Brookline business that operates with rotating staff or multiple keyholders. Our master key systems give property managers building-wide access while keeping individual tenant suites locked to their own keys. We also install panic bars, commercial-grade door closers, and access control hardware that meets Massachusetts building code — and we respond to commercial emergency calls across Brookline typically within 20 minutes.
