I have a Pro9544 Security system installed on my 97 blazer. My problem is when I try to use the ove-ride code it turns the siren off but when I try to turn the ingnition to start my truck the siren goes off again. My battery was removed for service and ever since the code hasn'rt worked. I followed the manula to reprogram it but had no success. Can someone please help and give me step by step intructions to do this or give me a place in the Cleveland area to go for assistance. E-mail me with questions
