We've been a customer of Citywide for about 2 years - we couldn't be more pleased with their service! Most recently we locked ourselves out of our house and they were so helpful in getting us in touch with a fantastic locksmith that was over so quick and was able to get us in our house with no problems! Thank you to everyone at Citywide for running such a great company!

Bob was the best! He put my daughter's service in and made it so easy to use.

My house was broken into the week of 11/30. I called Citywide Alarms and they responded quickly. I had a working alarm system installed in my house within a few days. The sales person and technicians were very professional and knowledgeable. The system is very user friendly and I absolutely love being able to use my smart phone to set and disable my house alarm remotely! I am very satisfied with Citywide Alarms and would highly recommend them to anyone in need of an Alarm system. Stephanie, Webster Groves, MO
