Outstanding locksmith service--excellent communication, prompt, and incredibly efficient. We needed access to an electronic safe that a tenant had locked us out of. The owner took the time to walk us through a detailed plan over the phone, and on the day of the appointment, she was able to open the safe within minutes. She is not only exceptionally knowledgeable in her trade but also very kind and generous. I highly recommend this company for all your locksmith needs. Thank you so much, Delta Lock & Key! read more

Emily was a lifesaver! I'm a realtor and had recently closed a deal in Antioch when one of the patio doors with a complicated mortise lock stopped working properly. Out of the four locksmiths I contacted, she was the only one who actually listened to what I needed without charging an arm and a leg. She was knowledgeable, professional, and most importantly, honest. I'll definitely be using her again in the future and highly recommend her to anyone looking for a reliable locksmith in her service area. read more

Emily has helped me before a few years back with a defective door lock and it was such a great experience that I reached out to her again today.

Thank you so much Emily, you're amazing. read more

Super fast and great to work with. We needed locks changed at a house we just bought. the locks we bought it with were super old and semi-functional. She replaced all the locks within an hour or so.

Our front door suddenly stopped working and the latch would not pull back when turning the knob. I thought for sure we would need to replace the knob and rekey everything. Thankfully, Emily came out and said, she could repair it by replacing a part from the mechanism. Emily professional and honest throughout the process. She saved us money by salvaging our existing door lock, giving us a functional temporary solution until the full repair could be made. This meant we didn't have to spend money on rekeying all of our locks. read more

********** SHE'S A GAWD ********* I arrived home couldn't get into my house. I randomly called a few Yelp locksmiths a few brief fone conversations left me feeling exploited. It never surprises me when anyone tries to capitalize on an emergency situation. Listen to this, I called Delta Lock and Key. On the other end of the phone was GAWD. SHE said "I'll be there in 15 mins" without hesitation. How she drove from Discovery Bay to Brentwood in 15 mins IDK. What I did know GAWD was on HER way. I wasn't even given time to explain the problem. GAWD was on her way!! Just like she said 15 mins later she pulled up to my driveway. EMILY is an amazing GAWD!! The BEST service I have ever received, seriously. SHE'S A BAD ASS!! She went over and beyond what I needed she didn't fandangle. She made me feel protected, safe and secure, Emily is a GAWD. She provided EXCEPTIONAL service. She worked in the dark with limited lighting and in the freezing cold. She took her time didn't rush and didn't cut corners. She is very professional , knowledgeable and the most amazing is she sincerely cares about her customer. I will never forget this experience and will share the story of randomly calling a business and GAWD answered my prayers. Thank you, Emily. (tears) SUPPORT WOMEN BUSINESSES read more

She rekeyed my entire house and made me 4 keys within 1 hour of being there. She was on time and made sure to text/call when she was on her way. 10/10 service and her pricing is affordable AND reasonable. read more

Called Emily at Delta Lock & Key as I had an older Lane storage chest with no key. It had not been open since my family member passed some years ago. Emily came out a short time later & opened it with no damage to the lock or chest. She also recommended a website to get a replacement key. While she was there I asked her to give me a price on rekeying several locks to minimize the number of keys. She said she could do it now. She was able to rekey 5 locks & replace a deadbolt & one key now fits all locks. This is the second time I have called Delta Lock & Key for service and was compelled to write another Yelp review. Emily does great work & her fees are very reasonable. I highly recommend her for your locksmith needs. read more

What a great experience. The door latch on our front door wasn't locking properly so we decided to call Delta Lock & Key because they had such great reviews. The technician showed up right on time and went right to work. She discovered the strike plate wasn't positioned properly along with problems with the lock itself and with our approval made all the repairs including moving the strike plate. We liked her work so much we decided to have her rekey every door in the house, something we had been meaning to do for a long time, and she also made us several new keys for the family. The final cost was extremely reasonable, so much so that I wish we'd had more for her to do. Great job, reasonably priced, and a wonderful personality to go along with it!! I can't recommend this business enough! read more

Emily is my hero!!!! My husband locked both keys in his gun cabinet and of course it was my fault.

She is also a super hero!! Thank you!!!!! read more

Emily is amazing. She is not has reasonable prices (lowest in town) but that's just the START. She is personable, flexible, came back the 2nd time since I didn't have the things ready to setup the smart lock... extra charges for an additional trip -- Zilch.... On top of that, I was like, can you help with the mailbox and she said just made it happened and didn't charge additional service fee for it..: I forgot to mention that when I called over the weekend, late night, she not only accommodated the urgency and was right on the job the next day morning. Yup, she is the real deal (I wish I didn't write this review and keep her as a secret, selfish me... but, she really deserves being the one and only to to person). Thanks Emily, keep up the great work. read more

Headquartered in Discovery Bay. I needed locks changed at my home in Brentwood. I went to Google and all of the sponsored listings really just suck your time and waste it. I came to yelp looking for a local locksmith, this lady instantly responded gave me a hard money quote and on Sunday showed up within an hour and changed all locks in the house. Very nice hundred percent effective stuck to the price and did a great job. I have her saved as my local Locksmith. read more

New Schlage electronic lock glitched and the keypad would not light up so could not enter the code. Called them up and 12 minutes later she was there trying to pick the lock. Ended up going to side door of garage. She picked that door and the one to the laundry room in about 1 minute. Got us inside. Examined the electronic lock and removing and reinstalling one battery got it working again. We think the battery connector is flaky. Had her make 3 more keys so we have some extras. Then was expecting a huge bill because it was a Saturday. Total cost was $75. I couldn't believe it. Wonderful service, great rapport and a very reasonable price!!! read more
