went out of there way to help friendly and reasonably priced
Great service. Nathan was so friendly and helpful. Highly recommend.
Skeleton Key’s key cutting service was extremely disappointing. It took FOUR visits before I finally received a working key. Visit 1: the copied key didn’t work Visit 2: the replacement key damaged my lock. Rather than coming out to rectify the issue, I was told I’d need to pay a call-out fee or remove the lock myself and bring it in — leaving my home unsecured Visit 3: I dropped off the lock and incorrect keys Visit 4: finally received a working key A very frustrating experience for what should have been a straightforward service. Hopefully the quality of their other services is better than their key cutting....
Fantastic service from Bryce at Alert Locks & Security! Incredibly professional, responsive, and efficient when we had a broken key stuck in two locks. Bryce handled everything with ease, and made what could have been a stressful situation feel completely under control. Really appreciated the friendly approach and expertise, 5 star service and would highly recommend!!!
chris and the team worked with me to solve the annoyance of having to fish the key out out of my pocket every time I entered my apartment. We have a small dog and I often take it downstairs to visit the grass area for a bathroom break. I’m always forgetting my keys which is no longer a problem. it’s also much more convenient when returning with bags of groceries Or anything in your hands. Thank you so much!
