Last time my car key showed a low battery warning, I didn't rush to replace it, thinking it could last a few more days. Surprisingly, it worked normally for opening/closing doors for two weeks, though the sensing distance became noticeably shorter - I had to stand right next to the door. By the third week, it started malfunctioning - I needed to press the button multiple times to lock the car, until it completely died and left me struggling to open the door with the mechanical key in the parking lot. My advice: replace the battery within a week when you see the warning. We rarely think about our car keys until they fail, and it's incredibly inconvenient when they do. Changing the battery is actually very simple - just buy a coin battery from a convenience store for a few bucks and replace it yourself by opening the key case.
