Servo as a door lock, How can I ignore a button until later in the program?

hi everyone!

i working on keepsake box uses mini servo lock door
(minimum security more prop proposal)

the sketch have created works in general sense, need little
guidance.  

button 2 (which closed when door closed , returns servo to
the locked position) depressed when circuit powered (because
the door closed @ beginning of cycle) , result, keeps
the arduino responding button 1 (which high signal
from source external arduino) opens lock. want
to cycle locked / unlocked leds using pwm not sure
park additional code.  i include sketch, in @ least finding
the answer awesome.

thanks!

const int led2 = 5;            // number of unlocked led pin ~
int brightness = 0;    // how bright led is
int fadeamount = 5;    // how many points fade led by

void setup()
{
 pinmode(btn1, input);        // set btn1 input
 pinmode(led1, output);       // set led1 output
 pinmode(btn2, input);        // set btn2 input
 pinmode(led2, output);       // set led2 output
 myservo.attach(9);           // attaches servo on pin 9 servo object
 myservo.write(pos);          // physicaly sets servo locked position (had problems servo twitching 30+ deg on startup)
 digitalwrite(led1, high);    // turns on locked led
}


void loop()
{        
   buttonstate1 = digitalread(btn1);    // @ dac pin
   buttonstate2 = digitalread(btn2);    // @ door switch

   
   if (buttonstate1 == high) {          // if dac pin high then,                                      
     myservo.write(pos1);               // move servo unlocked position
     digitalwrite(led1, low);           // turn locked led off
     digitalwrite(led2, high);          // turn unlocked led on
         delay (2000);                  // wait 2 sec prevent door switch bounce

     
   } else if (buttonstate2 == high) {   // if door closed switch high      
     delay (2000);                      // wait 2 sec prevent lock damage , make sure door closed
     myservo.write(pos);                // move servo locked position
     delay (500);                       // wait 1/2 sec before door locked led going high
         digitalwrite(led2, low);       // set door unlocked led low
         digitalwrite(led1, high);      // set door locked led high
   }
}

i don't understand question is. problem sketch see use of delay. way might loose opening signal if waiting door being locked. try eliminate these storing time of event , checking against millis().

i don't know why wanna display boolean information (locked/unlocked) using pwm (which kind of analog output). what's intention there?
