Parking brake is electronic. Hence why it's called "electronic parking brake". It runs on electrons not vacuum.
If it's not disengaging it's either the dash switch or caliper motor.
Replace the switch (stupid easy) or jack the car up and see which caliper is stuck. If it's both I'd venture a guess that it's the switch. If it's only one the motor is pooched.
If it's a bad motor unbolt the motor, wind the caliper (M8 spline I believe) and drive over to the parts store for a new one.
