- Intermittent functionality
Understanding these signs is essential for maintaining the effectiveness of your key fob. Here’s a detailed explanation of each sign and its implications.
-
Diminished Signal Range:
Diminished signal range occurs when the key fob’s battery weakens. The fob may not work from distances it previously covered.

Unresponsive Buttons:
Unresponsive buttons signify that the key fob might be running low on battery. When pressing buttons fails to yield results consistently, this suggests that the battery’s voltage has dropped. If functions like locking, unlocking, or trunk release are intermittent or entirely non-functional, it signals the necessity for a battery replacement. -
Blinking Red Light:
A blinking red light on the key fob typically indicates a low battery. Most key fobs feature a light that flashes to signal operational issues. If this light blinks rapidly when buttons are pressed, it usually signifies that the battery is nearing depletion. -
Intermittent Functionality:
Intermittent functionality occurs when the fob works sporadically. Users may notice that sometimes the key fob functions properly while at other times it does not respond. This inconsistency is often a direct result of a failing battery unable to maintain consistent power output.
Addressing these signs promptly can help ensure that your key fob remains functional and you can access your Acura TL without complication.
