<human>: I'll preface this by saying I'm usually not a stupid man but I was at the end of my third 16 hour shift in a row and I was very tired. I'll make this quick:

I got off work, went out to my car, hit the button for the doors on my remote unlocker - as usual. Nothing happened. I tried it a few more times, battery must be dead. I stand there for 10 minutes, mashing the little button, hoping for enough juice to open the doors. Nada.

I call a locksmith, explain that I'm locked out of my car. He says he'll be right over. 20 minutes later he arrives. He walks up with his tools, inserts a thing that looks like a blood pressure cuff in the door jamb. He starts making conversation as it inflates, pushing the door open:

"So locked your keys in the car? No problem sir, I'll have it open in a minute."

"No, my keys are right here, my key fob is dead." I replied.

He stops and for about 10 seconds. Doesn't say a word. He sees my keys in my hands. Takes them from me, inserts them in the lock and opens the door.

I was mortified. I was so in a habit of opening the doors with my remote fob that I entirely forgot that keys could be used to unlock cars manually. He started laughing so hard I thought he was going to have an aneurysm. After he stopped laughing, he told me there was no charge. The story he'd have to tell was worth the drive out.

Give me the gist of the text in a nutshell
<bot>: Key fob battery died, I was so in the habit of using it that I forgot keys could open car doors. Called locksmith to come laugh at my stupidity.
