Emergency latch gone button inside the vehicle the work. Why should I do.

 

OMG you could always use the button on your remote, I rarely use the trunk release button on my dash! How's that working for ya?

I've had issues where the key, under dash button, and under taillight button wouldn't work, but as soon as I turn the key to the 'ON' position everything works fine again - have you tried turning it off and on again? Also, check the switch in the glove compartment.
