What to do to reset the code, then? You will encounter many different situations in many hotels and it might be confusing. You will only hear a click indicating a released lock. In that case, the lock is not motorized and you will not hear the motor operating the bolts. Sometimes, dialing is not enough, you have to turn a big knob to open the door. Then check if the lock operates properly with the door still in an open position. Press enter or * to set the desired code. In those circumstances, I don’t want to spend much time figuring out how to use my hotel safe, read incomprehensible instructions in fine prints on bad lit papers. Usually, I relax with a beer or a good meal or both. I have spent several hours of tedious journey, and after long hours of work.
I usually arrive in a hotel after a long day away from home.
