How to Tell if Your 2005 Lexus RX330 Key Fob Battery is Dying

Several signs might indicate your key fob battery is nearing its end. Keep an eye out for these telltale indicators:

• Decreased Range: Finding yourself standing closer to your car to lock or unlock it? A weakened battery may be limiting your key fob’s signal strength.
• Intermittent Functioning: Does your key fob work sometimes but not others? This inconsistency can be a sign of a dying battery struggling to provide consistent power.
