Gave advice over the phone

“Julian was really helpful with free advice over the phone. My dog ate through an alarm cable and the alarm kept going off. Julian didn't have time to come immediately but gave excellent free advice which stopped the problem. He even called back to continue talking when he lost phone signal. Super helpful.”

Very efficient and courteous

“We were extremely satisfied with the work carried out by Julian the technician. He arrived on time and was very efficient and courteous. In addition to the service work, he also gave us information and suggestions to help us in getting the best from our system. This was our first experience with Key Security Systems UK and we would highly recommend their services.”

We had a client who's old system wasn't performing correctly and we suggested they got a quote from key security for a new one.
