Cos Cob Locksmiths from people just like you.

were fantastic. They explained everything to us and answered all of our questions. They completed all the work," and took care of a few minor adjustments in other parts of the house that needed attention. They also gave us some good security tips. They were friendly and polite. It is a great experience like this that makes customers for life!

"Everything went splendidly. After reading the wonderful reviews about
, I phoned to make an appointment.
N., the" dispatcher, was very courteous and was able to accommodate the specific time window I requested for the following day. I was hoping that Gilli would be the one coming to my home, as others have praised him. I got lucky. It WAS Gilli who showed up. He was very knowledgable. When I told him that my main concern was security, he suggested that I upgrade my deadbolt with one that cannot be picked using a "bump key." I had never heard of bump keys, so Gilli told me to Google it while he was here. I did so, and I learned a lot. Even though I ended up spending nearly three times my budget--i.e. $210 for one lock and two keys (instead of only $79 for two locks and three keys), I believe it was a FAIR PRICE (thus a "C" in the that category). But I didn't feel any "up-selling" pressure from Gilli. It was my own decision to upgrade, and I'm glad I did so. In all other categories I rate this company (and Gilli) with a solid "A." I will use this company again, and I will recommend them to my family and friends.

If you're locked out of your home or car, a locksmith can be your lifeline - but make sure you hire a reputable one.

Dear Angie: Are keyless locks — the ones with a keypad — as good as regular deadbolts? — Deb H. of Madison, Wisconsin

In addition to the roughly $100-200 for the lockset itself, I would expect from $50-100 range (depending on your local labor costs) by a locksmith, ASSUMING you get a lockset that uses the existing door and frame lockset holes - should only take about 15-30 minutes in that case. Could run into maybe $100 more for a carpenter or the locksmith to fill and glue the existing holes and then drill new ones if lock does not fit the existing (probably "standard" hole spacing and setback - or maybe $200-300 more for carpenter to put in entirely new striker side trim and paint to match if you don't like the looks of the filled holes.
I understand your concern - but locksmiths are criminal record vetted and bonded pretty well, so not a major risk there. Unless you bought the deadbolt and entry lockset as a boxed set - both keyed the same - it would be normal for him to rekey so they use the same key. People do not want to have to fumble with two different keys to get in, so he probably just did not think to ask if you wanted them the same. Is it also possible he was keying to match a back or garage door lock too so all your entry doors use the same key ? A large portion of their work is rekeying locks after change of tenants or owners, or changing out a worn out lockset, so that would be second nature to him to do it - I don't personally think you have a high risk from this, unless perhaps you live in a very upscale house and had a lot of valuables laying around that he could see while working. If that $66 million Van Gogh painting you bought yesterday was leaning against the entry wall waiting to be hung, then I might be a bit concerned - otherwise not.

Locksmith reviews in Cos Cob


Great service! Arrived the same day as my call, was prompt and courteous. And was able to remove the broken key from my lock in minutes even though my husband and I had spent hours attempting to get it out on our own. Well worth the money, would use again.

answered all the questions I had, offered advice about the choices I needed to make, and completed the job swiftly and skillfully. I'd call him again anytime without hesitation and I recommend him without reservation.

I was very pleased with the work that Bulent completed at my house today! He installed two new deadbolts to doors that had to have the hole drilled, fixed the one I messed up, and rekeyed all of the doors and locks to the same key. He was prompt, polite, and even cleaned up after himself when I told him not to worry about it because the house is still in the construction phase and a mess. Very happy I chose

I called another company first (because they were cheaper) and they said that they were unable to rekey the front door of my home because of the type of the lock. I called

Cos Cob Locksmiths Provider Name Locked
was fantastic! He informed me that all 7 of our deadbolts were not engaging properly after he had chipped out the wood in the door frame so they would. He also put on a new keypad door knob. He was very friendly and professional and the extra work he did was at no charge. By far some of the best customer service we have received from the many service providers we have used since moving into our new house.
- Marc M.

Office staff is friendly and responsive and the technician came on time and finished the job quickly. They did exactly what they said they would do from start to finish. My only suggestion is to please identify themselves by name when answering the phone so I know if I'm talking to the same person when I call back.
