Nathan and Sean were simply amazing! They were able to put a small 1000lb safe onto a pallet safely for me to transport. These gentlemen were timely, professional, and used their wealth of experience to make a logistically complex job look easy. They constantly reassessed the game plan with each move to ensure the job was done safely to reach the end goal.I simply cannot say enough about these guys, and the excellent customer service I received on my initial call to Yaneth. Grah Safe & Lock went above and beyond my expectations and relieved me of a problem I had to deal with.If you are looking for true professionals, excellent customer service, and the skills to back it all up, I highly suggest you contact Grah if you have any safe moving needs!! Thank you so much for your help!

Nathan is the ultimate in professionalism. He showed up on time with all the equipment he needed to open our safe and repair it with new parts. He knows what he is doing, works fast, takes care of the surrounding items, leaves the work area clean and in the same condition he found it. We HIGHLY recommend him to do the best job for your locksmith needs. They are the best. Thank you!!!!!

Extremely helpful, knowledgeable, and cheerful staff!I had a gate lock that *had* to be installed, and another locksmith fell through. They couldn’t come out and install it that day, they could prep the lock for installation in their shop, no charge. Which they did. I’d never installed a simplex (push-button) gate lock before, but with their help and preparation, my self-installation was a snap!My thanks to Sean who found a hard-to-find latch change, and especially Aaron and Zach (between those two, help from A to Z 😁) who set the lock up for me. Also, special thanks to the boss lady for her accommodating and cheerful authorization.I would always consider using this shop!

The most professional company I’ve worked with in a long time. My fire safe wouldn’t open and they dispatched Nathan within the day who clearly had a wealth of knowledge and quickly assessed the problem. The part came within a few days and they were immediately there to install it. He had to drill the safe to undo the mechanism which I thought would ruin the safe but no! Not even a scratch and it is back to perfect order. A real locksmith is a true craftsman and I was so impressed with him as well the the communicative office staff.

Outstanding security door repair with hardware installation by a most experienced professional. Jesse, my engineer, assessed and performed the work thoroughly for high security and a clean, finished look. He was very organized and efficient, attentive to my concerns and provided expert suggestions - which I took. I am very satisfied and have new peace of mind regarding the integrity of my doors and locks. I highly recommend Grah Security for anyone needing these services.
