GXJeff

New member needs help! I have a 2005 GX. Alarm goes off for no reason and after deactivation with key fob, ALL lights will come on by themselves after 30 minutes unless lights are completely off. I've read threads on the alarm and I'm overwhelmed with where I should start (switches vs bumpers vs batteries). Can I just disable factory alarm?

Car battery tests strong according to auto part store. Key fob batteries seem OK too.

NOTE: Valet at airport had to jump my GX after trip and until I left battery disconnected overnight, car would not open using keyless entry. Related?

Thanks in advance!
