Nissan announced Wednesday that it will offer a new skill for Amazon Alexa that gives you control over certain connected-car functions using just your voice. You'll be able to lock and unlock the doors, honk the horn, flash the lights and start or stop the engine.

Alexa can't help you if you lose your keys, though.
