Crack the code

You now reach Turkey. Tired by your journey, you decide to go sightseeing in the town of Istanbul. Inside the Hagia Sophia, while you are walking, you find a key-ring which has two keys on it, with a key chain as shown below. En route outside the castle, you nd out that the escape is through a channel, which has two doors one behind another. Above the 1st door, it is written “Alphabet starts with ‘a’ ” “Look down to up, and you’ll see something interesting that satisfies me”. So you plug one of the keys into the door. A sentence appears on it, along with a keyboard. “Alohomora”. You decode what the sentence means and type in “eszrzxzbe”. The gate opened, sucking in the key plugged in and exposing another gate, with another sentence written “Incendio”. Suddenly the owl faints due to very less oxygen and you are left to decode the code. What do you type in to open the gate?
