If it is not in either of those two places, check your center console (near the shifter), or in the small compartment in between the driver's and passenger's seats (if you have one). These are the normal places that you should be able to find a trunk release button ... if it is not in any of these places, you might not actually have a trunk release inside your car -- you might just have to use the key to open it.
