On two separate occasions, Will and Kevin scheduled my appointment promptly. They fixed a poor installation (not done by them in the first place), installed new 'smart home' door hardware, tuned up existing hardware and re-keyed locks to provide a 'master' key and 'guest' keys. Friendly, professional and reliable. They know what they're doing!

This guy knows his job! I was in a dire situation: while filling up my Honda motorcycle the cap fell from the top of the pump, the key got warped and twisted under the weight of the metal cap and it didn't start the ignition any more. It was the only key. I left the motorbike at the gas station overnight, then went to 1st Lock. The guy there tinkered on the old key and brought it into shape enough to be able to make a copy, which, hurray, did work perfectly (the older key still does not). If this attempt had failed, I may have had to get all 3 locks of the Honda replaced at the dealership with all the cost, fuss, and time bike-less (it is the week of July 4th). Thanks 1st lock, great service, fair price (9 bucks for one Honda/specialty key ... I made a second copy to avoid other misadventures). I could not be happier!

I am so happy that I contacted 1st Lock and Security today. They came out the same day and re-key the locks for us. W have an old Baldwin lock for our front door and we like it very much. But we lost a key recently so we decided to rekey the lock. Zach came out and got this done in 20 min. He was on time, quick and efficient! He also greased this lock and another lock for us. Now these locks worked fabulously! The service response is very quick. And the price is very reasonable too. I highly recommend 1st Lock and Security who needs their service!

Locked myself out of my condo one day when I was home sick. My neighbors who had my key were all at work, so I need to call First Lock. Gary came by in about 15 minutes (thank you, thank you, thank you!) and got me in quickly. I would highly recommend him for his professionalism and attentiveness.

I had a Baldwin lock set that had worn out and needed fixing or replacement. They had the repair kit in stock and even helped me understand how it needed to be installed. All at a very reasonable price. They are real professionals and do it with a smile. A+

I'm super impressed with First Lock and Security. Gary was efficient, professional and friendly from my first interaction with him to the completion of a very large project. We needed to replace several different doorknobs, install deadbolts and rekey several of the deadbolts. Gary created and adjusted the estimate quickly.

During the installation, his team was incredible. They worked together. They were much faster than we anticipated, and they cleaned up as they went. We barely noticed their presence and everything is perfect.

Gary from First Lock came by a few months ago on short notice to replace part of a lock after a burglary at my home. I had asked several locksmiths whether they could swap out the bolt in an existing lock with a longer one due to the gap between my door and the doorjamb, but they seemed uninterested or confused by the request. First Lock was able to help me out in a prompt friendly manner.

I was having trouble with the front door of my business. I called First Lock one evening and they indicated that they could come out and take a look at it the following Monday. And guess what? The tech showed up Monday on time and fixed the door and lock!!!! Awesome customer service and I would not hesitate to recommend this company to anyone.

Zach was great - he arrived in the window of time that we had previously arranged, walked me through what my options were for reinforcing or adding to my existing lock systems at home, was polite and efficient (and was also understanding that I was trying to take a work call while he was installing the locks, since many people are "WFH" right now). Final cost came to exactly what was discussed over the phone. I fully recommend 1st Lock.

I was easily able to get an appointment. Will came and installed a new lock in a sliding glass door and repair a lock on a screen door. Excellent customer service and a very competent repair person.

Elizabeth K Menlo Park, CA

Our back door lock was broken. Zach immediately (10-15 minutes after I called) came to our home to take a look and within another 15 minutes had the lock fixed. Zach actually adjusted the lock alignment so that it worked more smoothly than before it was broken. Zach was efficient, knowledgeable and did high-quality work. I definitely recommend First Lock.

Phyllis S Los Altos, CA

Love this place. Has your mom and pop shop feel with excellent customer service. We used them for some complete door lock issues and they tech fixed it! We went back to them for an in home safe and they had an excellent selection and delivered the next day. We'll be back!!

Debbie C San Carlos, CA

Prompt response to my phone call to fix my broken front door tumbler.

A serviceman was dispatched promptly, and knew exactly what to do to fix my lock. It works better than when knew.

Professional, courteous, prompt, competent and clean. I thought the price was fair and reasonable also.

Bill C Redwood City, CA

Quick, polite and timely. You can't ask for more. I have an old house with an original lock and bolt on the front door. I wasn't sure if it would have to be replace but Zach came out and fixed it. Very happy with 1st Lock

Will of 1st Lock re-keyed three exterior doors (5 locks) for us in less than one hour. He was helpful, informative, clearly experienced and knowledgeable. He reduced the number of keys we need from 5 to 2 (which is very cool). He also left our (new) front door handle in better functioning shape than it was before. We highly recommend his services.

Sylvia S Palo Alto, CA

Used 1st Lock twice recently. First time was to fix a deadbolt on my front door that had always annoyed my family because it was difficult to turn and open. 1st Lock came out quickly and fixed it, now it's as smooth as glass. Second time was to duplicate an unusual key for my locking mailbox, although 1st Lock didn't have the required key blank in stock, they helped me order it from Amazon. The blanks came in a set of 4, I only needed two, so in exchange for giving my extra two to the shop I got the other two keys cut for free. Great to have a brick and mortar locksmith still around and doing professional work.

Tony Q Belmont, CA

Great guys here. Went in looking for a screw to secure a plate on my door jam. The gentleman took the time to dig through a few handfuls of screws to find what I needed. He could have just blew me off and told me to go find a hardware store. I really appreciated his help and would absolutely recommend anyone come down and check out this beautiful little shop. Thank you First Lock I will definitely be back.

Bill A Mountain View, CA

I've used 1st Lock on two occasions now and am happy to have a go-to, reliable, highly competent locksmith service. They were great for a standard job in preparing a door knob. But recently, they helped me with a more high tech solution and installed a Nest smart lock. They were extremely talented and knowledgeable in doing the job. Everything went super smooth and the Nest works fantastic!
Highly recommend this team!
