Is this what you need?

// motion detector senses something then a door opens

const int MOTION_PIN = 2;         
const byte LED_PIN = 13; // LED pin - active-high
const byte BUTTON_PIN = 12;
#include <Servo.h>
Servo servo1;

void setup()
{
Serial.begin(9600);
// The PIR sensor's output signal is an open-collector,
// so a pull-up resistor is required:
pinMode(MOTION_PIN, INPUT_PULLUP);
pinMode(BUTTON_PIN, INPUT_PULLUP);
pinMode(LED_PIN, OUTPUT);
servo1.attach(9);
}

void loop()
{
int proximity = digitalRead(MOTION_PIN);
if (proximity == LOW) // If the sensor's output goes low, motion is detected
{
Serial.println("Motion detected!");
openDoor();
holdDoor();
closeDoor();
holdDoor();
// wait for pressed button to open door from insided then

	int button_state = digitalRead(BUTTON_PIN);
	if (button_state == LOW) // If the button press
	{
		openDoor();
		holdDoor();
		closeDoor();
		holdDoor();
	}
}
else
{
	digitalWrite(LED_PIN, LOW);
	Serial.println("No Motion Detected");
}

}

void holdDoor(){
servo1.write(90);
delay(5000);
}
void openDoor(){
servo1.write(0);
delay(6000);

}

void closeDoor(){
servo1.write(180);
delay(6000);
}

It still goes through the loop and does not wait for the button to be pressed
