I have a 2005 Highlander and my handyman for my rentals uses it when he does my house repairs. Today he called and said it wouldn't start so I thought it was the battery since it's been so cold and it's not my daily driver. 10 minutes later he called and said it magically started. So 2 hours ago I was going to run a few errands and decided to use that car and I noticed the security light was flashing. I put the key in and then just my luck the car won't start. It has full juice, radio, windows, lights, even hooked up jumper cables from my other car thinking the battery was a little weak and throwing something off but nada. So for the past 2 hours I have been under the dash, checking wires, looking for an alarm kill switch but I can't find anything. I pulled the neg terminal for 30 minutes hoping that would do something but I still can't get the immobilizer to disengage. Also when I bought it a year ago it came with only one key and no fobs. I bought 2 fobs on ebay and programmed them myself.
Any ideas before I go crazy here?
