device that can unlock doors

just google "tk103 gps lock unlock doors"

This is what I've been looking for, thank you!!!!

Any tips on finding someone who can install these?

I'm in Phoenix, AZ.

Would a regular car audio place know how to do this stuff?

I have 3 Honda Odysseys I want to put them on.

I wonder if this would void the warranty I have on one of my vans, most likely I suppose.

I hear you. There are 2 companies that have these features on their devices: MooveTrax and TrackMate. Does anyone know any other company?
