Hired a locksmith from Master Lock & Key Store. A neighbor recommended them highly and passed on their number 510-404-0387 to me. Since I was new to Castro Valley , I didn’t know anyone else and called them up without thinking twice. Very reliable, on time, and knows what to do. Got the job done in less than 30 minutes. Back where I come from, locksmiths would take hours to respond and an even longer time to get the job done. Will I hire them again? Yes. I’ve found my go-to locksmith. Highly recommend them to all!

Great Company and fast. I called and they came in literally 5 minutes and had a new cylinder in 2 mins, if you will need a Locksmith any day I will call Master Lock & Key Store at: 510-404-0387.

Used Master Lock & Key Store only yesterday to have two spare keys made for the front door lock. Scheduling services was easy – I didn’t have to call them. All I did was drop them an email on [email protected] and I got a response confirming my request. The technician got there five minutes early and completed the job quickly. Hassle-free and affordable! I would definitely use this locksmith again. Hands down, the BEST in Castro Valley , CA 94546..

Master Lock & Key Store is absolutely the best! This is the second time I’ve worked with them and I couldn’t be happier with the service provided. The first time I hired them was when I had issues with the front door lock. James went above and beyond to ensure that the new lock fit properly. It was quite a feat considering the fact the house was old and the previous lock had been in an extremely poor condition. The suggestions were incredibly insightful and helped me pick the right lock for maximum security. The second time I hired them was in an emergency. I got locked out of my home past midnight and called their number 510-404-0387. A technician, Mark I think his name was, got there within 20 minutes and took barely a minute to open the lock. I will never use another locksmith again. Master Lock & Key Store is great, be it for emergencies, or standard everyday work. The best in Castro Valley , CA. I can’t recommend them enough!!!

I was heading out for a business trip and I wasn’t willing to leave my condo at the mercy of the old cylinder lock on the door. I knew I needed to get it changed. Thanks to Joe from Master Lock & Key Store for getting the job done at such short notice. He got there in like ten minutes versus the 30-minute timeframe he’d earlier given. Once he arrived at my place, drilling the hole to make way for the deadbolt and the complete installation took him just minutes. Completely satisfied with the quality of work! Joe is the best in Castro Valley , CA and I’ll feel 100% confident calling his team again in the future. Would I recommend them? YES!

I was locked out of my condo and didn’t have a spare key. I was already freaking out, add to that a bad phone connection and what you get is the perfect recipe for a mini-meltdown! Being unable to voice out my concerns to David via phone, we resorted to texting. Huge thanks to David from Master Lock & Key Store for being so supportive and understanding! He helped me get back in within five minutes. Thanks for being so responsive – and everything else! If I ever need a locksmith in Castro Valley , CA ( I hope I don’t), there’s no second thoughts! I’m definitely calling Master Lock & Key Store again! Saved their number 510-404-0387, just in case!

Ok, just adding to the mountain of good reviews here... The lock on the door to my apartment was busted. So I tried to save some pennies by posting an ad on Craig's list a method that has worked really well for me to hire my cleaning lady and various handymen for simple jobs. Anyway, after sorting through like 50 replies to the ad, which quoted me prices varying form $100 to $300, I chose some guy who said that he installs locks in hotels for a living for $100 who of course turned out to not know what he was doing. He did put in a good effort, staying wiht the job for like 5 hours! But the door knob was basically hanging off the door the next day after using it twice. Anyway, a week later after calling a bunch of legit locksmiths who wanted $80 to even look at the lock, and who wouldn't commit to a firm price, I called Master Lock & Key Store who fixed the mess that was made for $80 in like a half hour.

This is from a while back... but nonetheless, great, speedy service, highly recommended! The best Locksmith Company in Castro Valley , CA 94546!!
