I just bought a 2012 Odyssey Touring Elite a few days ago and already drove it across the country without issue. Nothing seemed abnormal. I get it home and now the alarm sounds every single time I press the lock button on the key fob and start to walk away. Pressing the unlock button stops the alarm. I tried some of the tips on YouTube about disabling the alarm under the hood, but it didn’t work (all videos were for older model Odyssey’s, so I may not have been doing it right.) I noticed a little blue blinking light under the steering wheel that hadn’t been blinking before, so I went ahead and disabled that which did the trick. The car now locks without triggering the alarm. The problem I’m having now is that with the little blue light off (if someone wants to tell me the name of it, that would be great), the horn honks quickly 3 times when I turn the key in the ignition. Any idea what is going on here and how I can fix it? Would like to avoid heading to the dealership for a diagnoses if I can.
