Great Service

Devin Ferebee from Lakewood, CO

The ignition cylinder on my truck failed leaving me with a 3 ton driveway ornament. After some research and being told that I needed a completely new ignition cylinder (and new keys that wouldn't fit the door locks unless I paid to have them all matched to the new cylinder key) by another locksmith and an auto parts store I called Alexius. Their tech came to my location with the right parts and tooling to rebuild my original ignition cylinder and match it to my existing keys. He noticed that one of my keys was getting worn and made me a spare while he was on sight at no additional charge. Great , quick service at a reasonable price. I couldn't ask for more. Nice job guys!

Quick, great service

Caryn Jones from Aurora, CO

Nothing like having your 3-year old lock the bathroom door and pull it closed (thankfully he was outside the bathroom) and THEN finding out that the previous house owners installed the lock wrong so the easy fix wasn't working. Express Locksmith came within 30 minutes and had it open and fixed in no time and for a very reasonable price. Thanks!
