It’s too bad you didn’t hear the slightly smaller bell that alerts you of a malfunction of the little bell.

I once drove 12 miles away from my car keys and had to abandon my unlocked car at a seedy gas station to Uber with my two toddlers to my husband's work and back to get the keys from him because the car didn't yell at me like usual when he got out with the keys in his pocket.

please tell us your phone was in your pocket.

This just reminds me on Breaking Bad. "The buzzer. The buzzer that let's you know the keys are in the ignition."

How often do you leave the keys in the ignition?

That bell seems overworked. How about remembering your keys instead of relying on something to tell you you're an idiot?

Please, learn the use of commas.
