I had an issue with my car (Again) and I needed to have the alarm disconnected as it wouldn't stop and I couldn't start my car. I called Cooper after reading reviews and he promised to be here in thirty minutes, on Christmas Eve no less. He arrived as promised and not only took care of my issue, he gave some advice regarding the knucklehead who did a lot of after market work on my car. Not only was there a factory alarm, but there was a secondary one. He removed all the useless wiring and I am good to go. I would recommend Cooper to anyone who needs an alarm serviced or installed
