Toyota Repair Problems? Ask a Mechanic for Answers ASAP
Hello and welcome to just answer and allowing me to assist you. Question to give me a picture of what we are dealing with, is this system an aftermarket or factory Toyota installed unit?
Hello again, I see you replaced the key fob battery. but did you check the vehicle's battery lately for if it's not supplying enough power to the systems they won't work properly.A low battery can trigger remote starters and anti theft devices to work or do funny things . as all computer devises go garbage in garbage out,So first of all do a load test on your vehicles battery and let me know so we can go further if necessary Hope this helps and if you need further assistance I'll be happy to do so..
hello again , just to repeat a question , did you check your battery load test? the alarm system will disable it from starting but if the battery is low or not holding a good charge that will by itself trigger the alarm system do a battery load test and get back to me
