Default strange battery drain in a 2011 Grand Caravan

Something is draining the battery of my brothers recently purchased van. Possibly a security system.
Does anyone know what this is? is it a valet button? who makes it? if it is.

I had purchased a remote car starter and it worked perfectly for about 1 year. She then started having a parasitic drain on the battery that would prevent it starting from day to day. I finally disconnected the WIN module that was installed and the drain disappeared. Maybe a similar issue.
