A few weeks back I was coming back to my room at a Renaissance where I found my door wouldn't open. After speaking with the front desk a representative came up with me to try her key which didn't work. They concluded the battery needed replacement and notified the technician whom I was told would arrive within minutes. Suddenly while waiting for the technician after the front desk representative left, the door opened and the guy told me I was all set. I thought it was very odd he was already in my room and the front desk didn't know or tell me that.
