Very professional and affordable service! We were new to Waltham and didn’t know any locksmiths around. Hired Keystone Locksmith Shop after a neighbor recommended them strongly and passed on their number 781-519-7432. Arrived on time, finished the work quickly and cleaned up any mess made thereafter. Charges were fairly reasonable, despite the fact that I’d had about two locks changed and four locks rekeyed. Won’t hesitate to hire again…

I hired a local firm to help with changing the locks of the property before the tenants moved in. Even after frequent reminders and two visits to the shop, I was left waiting endlessly for a technician to be sent. Finally, at around 10 pm I’d accepted the fact that no one was going to come and started looking for other options. Found https://www.Waltham.Keystone-Locksmith-Shop.com on the web and these guys instantly agreed to come. I’d waited no more than fifteen minutes, when a van pulled up outside the building. Joe and his team got down to work immediately and managed to rekey all the locks within an hour. Despite the short notice and the overnight work, I wasn’t charged anything more than the base rate. I’m completely happy with Keystone Locksmith Shop and I’ll definitely recommend it to my family and friends in Waltham, MA… hire them, you won’t be disappointed. These guys are the BEST!!

Good job by Keystone Locksmith Shop! Couldn’t afford to buy a new transponder key, so I was on the lookout for someone who could fix it. Most firms didn’t take up the job simply because it was too much of work for too little money. Thanks to Eric for going out of his way and helping me. The chip replacement came in at a nominal cost and the key worked flawlessly. Thanks again! I would recommend them to all in Waltham, MA…

I would, and have, recommend Keystone Locksmith Shop to anyone looking for a locksmith. Shon come the day after my inquiry to change our lock. He was very knowledgeable, giving us an overview on what the existing lock was like, etc. He even recommended a cheaper service that what I initially called him for after looking at our lock. Service was very quick, and he left everything clean and tidied up. Didn't rush us through or seem hurried, chatted with us throughout the entire install, even recommending a couple of great pizza spots in our neighborhood. It felt great working with someone who was friendly and didn't try to cheap us out of our money!

Despite the short notice, Keystone Locksmith Shop rushed to my aid. The usual locksmith I hired cancelled on me at the last moment, and I really needed the push bars fixed before the inspection. Ed and his team worked quickly and restored the exit locks to perfection in no time. Can’t thank them enough! Hire them if you need reliable service in Waltham, MA 02452..
