I had a very positive first experience with Advanced Lock and Security, I needed a couple of my locks changed in a hurry so I looked up some companies online and happen to come across their business. I was very impressed with the quality of the service and how quickly they were able to complete the job. It was a holiday weekend but they were able to complete the job in about two days. I would happily refer them to anyone needing service and will definitely call them first if I need any service in the future.
