My ford remote start was working fine until lately it doesn't always send the signal when i try to start it. I changed the battery in the key fob but it still having issues, when i press twice on the button the led doesn't flash twice to confirm that it sent the signal and the truck don't start. I keep trying it but then the fob starts beeping like 5 times and the truck don't start. Any ideas what could be the problem?
