Fantastic service way above and beyond my expectations! Was able to schedule same day service. Even helped to jump start my vehicle when battery unexpectedly died, which was obviously not the original reason they were at my residence. Definitely will reach out again for my future locksmith needs. Thank you for the excellent service! read more

Diamond Locksmith did a great job on 80 yr old front and back door locks! Front door latch needed repair, replacement of parts and now works perfectly. Back door never had a keyed lock and now it does. Highly recommend Diamond Locksmith. The price is reasonable and they show up when expected. read more

Professional, fast and a really nice man.Prices are reasonable too.

Great and prompt service! Ron shown up in 20 minutes right after I called, he found the problem at no time and also duplicated 2 keys for me right on site, all in a efficient and professional manner, highly recommend! read more

Unfortunately, my first yelp review is due to my own carelessness. I should have wrote this a couple of weeks ago, but perhaps the embarrassment from this comical experience subconsciously played a part. It was later in the evening when everyone is at home unwinding from their day. My girlfriend and I decided that we should pick up some take out as we are both tired from our long day. We walk out the door and I lock it like I usually do and right then I see the "please tell me yo grabbed your keys because I didn't grab mine" look from her. Of course I had not. Both key-less and without food, we yelp to find someone that will come out quickly to get us back in our house and speed up the process of food intake into my body. I'm already expecting this to be a long night at right before finding Diamond Locksmith and give them a call. They tell me that someone will be at my door in 15 mins, so my girlfriend walks down the street to just pick up some burritos. A car pulls up and it is Ray. I look at my watch and its less than 10 minutes. WTF?! Long story short, I'm on the couch watching TV and my girlfriend walks in with my burrito. Perfect ending! Thanks again Ray! read more

Called Ray again for help with my Moms house and he delivered great service, arriving in just minutes of my call. Thanks Ray read more

One of the locks in our 20 year old Marvin door stopped locking. Diamond was easy to schedule, arrived on time, and fixed problem in short order. Highly recommended. read more

I'm a realtor so I've had the opportunity to us Ray several times, he is fast, timing, an offers competitive pricing. What more can you ask for. My clients are equally happy with his services. Don't hesitate to call him. I had a house with four different keys for seven different locks. Not anymore, 7 locks - one key! read more

Couldn't get my bedroom lock unlocked, and unfortunate situation that I've been trying to do for over five hours. Called diamond locksmith, and Ron came within 20 minutes, and didn't charge me an arm and a leg. Incredibly kind, professional, overall wonderful experience. If I happen to get locked out again, I'll call him for sure! read more

Asked for a price estimate last night at 1030pm and got one. Ron came out the next morning. i showed him my doorknob and how the key did not go all the way in. Also had a deadbolt that needed to be keyed. Ron fixed them both quickly and professionally. He gave me close to the price estimate for a fee. I will recommend this Locksmith to all of my family and friends. Thanks again guys for coming out on such short notice. read more

Fantastic service! Called to replace keys on two locks. Was able to schedule an appointment easily and he came and did the job in less than 30 minutes. Quality work and done quick. Thank you! read more

Marco came after 5pm and stayed for 3 hours. He rekeyed eight locks, most of which were old and had to be cleaned. He was supremely patient and kind. Highly recommend and we will definitely call him again if the need arises. read more

Ray came out and fixed the lock on our street-facing door. While the fix itself looked rather simple, he put the time in to make sure it was done right, and he didn't object to me hovering over him, taking pictures of the work in progress. He told me that he'd return free of charge if the fix didn't hold up, but so far so good. He wasn't the cheapest estimate I got for that job, but he wasn't the most expensive either, and he gave me his license information before I agreed to hire him. read more

Very satisfied with the service, Amir was highly professional and courteous. I had a lock out and he was able to quickly resolve the situation and provide excellent service. Thanks Amir! Will refer to friends and family. read more

Ray is a great locksmith. He's fast, very punctual and well prepared! I would highly recommend him to anyone with auto locksmith problems!

WOW what a great experience! Amir showed up what a great and friendly attitude, and got right to work less than 30 minutes I had a brand new key! I will definitely call them again without hesitation. Best prices with great customer service???? You can't beat that!! read more

If you've locked yourself out of your car or lost your key(s), this is the locksmith to call. I would HIGHLY recommend Diamond Locksmith. Our tech was friendly, got to us in a timely manner, and the price was totally reasonable. Hopefully we never have to use again, but if we do, I know who I'm calling! read more

I was locked IN my house. Yes. IN my house. I Yelped this place and Ray arrived within ten minutes. He was accommodating, quick, and friendly. Saving their number in my phone. My go-to! Thanks for getting me out of my house, Ray!! read more

Super efficient, extremely friendly, absolutely outstanding service! Thank you very much Diamond Locksmith!

Accidentally locked out of the new apartment on a Sunday afternoon/evening. Called Diamond Locksmith and they arrived and opened the door within 15 minutes. Even got some keys made. Fantastic service. Highly recommended. read more

This review is long overdue. A few months ago, I lost my key while walking the dog on the beach. I was grasping onto hope that I might recover it, but after a few days, it was time for me to face the music and call around to get some quotes for a fob replacement. Ray offered a replacement for several hundreds less than the dealership or other locksmiths. He was a great communicator, arrived within the window of time he'd estimated, and overall, I had a fantastic experience. I ended up sharing his information with several folks on their own fruitless key-search missions. If you need someone who is reliable and affordable, I would highly recommend Ray and Diamond Locksmith! read more

Marco contacted me minutes after I searched on Yelp. He arrived on time, fixed my broken lock, and was very friendly and helpful. I highly recommend him. read more

We have a door to the crawlspace and no one knows where the keys went. Called Diamond Locksmith who sent Marco to inspect on the same day. He was great. In just a few minutes he had the door opened and was making replacement keys! Quick service, excellent work, and at a great price. Highly recommend. read more

We locked our (simple) bedroom door by accident and contacted Diamond. They were very responsive and tried to get to us within an hour on a Sunday!! We ended up going with someone else who was already down the street but we wish we had stuck with Diamond because their quote was exactly HALF of what we ended up paying :'( read more

I got locked out of my apartment at 3:00 am! Ray came right away and was awesome! Took him less than 5 min to do it! Highly recommended :) read more

We called Ray today to give us an estimate on installing deadbolts in our French Doors. Imagine our embarrassment when he noted that deadbolts were already in place - we just didn't know it, and didn't know how to use them. Ray easily showed us how to operate these hidden locks, and left without accepting payment even for a service call. He was pleasant, prompt, and obviously knowledgeable. When we need "real" work done, we're not going to hesitate for a second to call him back. read more

Ray absolutely nailed it - fixed my damaged lock set and rekeyed it at 10pm Sunday eve. I appreciate all the hustle and professionalism. 5 star for sure! read more

Amir helped rekey the locks at my home; he was very kind, prompt and professional. He even went out of his way to make sure my door was aligned correctly! Above and beyond - thank you, Amir! read more

What can I say? Ray is the real deal. I don't give out a ton of 5 star reviews on Yelp, but when someone demonstrates outstanding communication and then backs up their words by delivering quality work in a timely fashion without overcharging you for their valuable service, I really can't help but sing their praises. Ray went above and beyond his call of duty by agreeing to meet me near his residence long after all other locksmiths in the area were closed. When I got to his location, he was still sitting at the table and enjoying dinner with his family, but as soon as he got my text, he proceeded to get up from his chair and, without hesitation, went outside to greet me. If that act doesn't capture the essence of 5 star customer service and help highlight the true dedication of a professional to his craft, I don't know what does. read more

I've had Ray replace the front door locks/handles on my past two homes. Both were built in the 30s and quite challenging. He is fast, efficient, and clean. Seriously--he used a cordless vacuum to clean up the debris. Much appreciated! Would recommend him to anyone :) read more

Ray is amazing! Replaced our lock within 15min and patiently explained why the old lock didn't work. Reasonable price. Highly recommended

Rey was spectacular. Got my keys swiped at the gym and he was there at the exact time he said he would be. Made two new Prius smart keys in about 30 minutes. Price was super reasonable compared to other locksmiths on yelp (and the dealership) and it was the same night my keys were stolen. Super nice guy too. 10/10 would recommend. read more

Seemed expensive. The technician also used my information to later hit on me. I called the owner to complain and he couldn't have cared less. Completely unprofessional. read more

Fast and amazing service for a new key! I snapped my only truck key in half and Ray was there in less than an hour in traffic and had me back on the road less than 30 minutes after his arrival. Thank you for being a lifesaver!! read more

excellent service! Email response was fast and he was at my house me within 2 hours of contacting them. Reasonably priced as well.

I needed a new door lock. it wasn't a straight forward job. I had good communication with the owner and the technician. This was after dealing with Rex Security on University Avenue (i will not use them again). There were some small problems in parts and scheduling but ultimately quality work was done in these trying times. I would recommend them. read more
