Have an 08 Mariner hybrid went to back it out of garage and it would not start. At first I thought the battery was dead but then I noticed the security system light on. I cannot find a way in the owners manual to reset the system other than it says to take it to the dealer. There has to be a way to reset the system. I left the positive battery cable off for three hours and that did not work either. I hope somebody knows how to fix this???????
