The key fob for your 2020 Toyota Highlander is a critical piece of technology that allows you to lock, unlock, and even start your vehicle remotely. Like any electronic device, your key fob relies on a battery to function correctly. Over time, this battery will eventually lose its charge, potentially leaving you stranded without a way to access your vehicle.
This comprehensive guide will walk you through everything you need to know about your Toyota Highlander 2020 Key Fob Battery, from identifying the signs of a dying battery to replacing it yourself.

Before you find yourself stuck in a parking lot with a dead key fob, it’s essential to recognize the warning signs that your battery is nearing the end of its life. Here are a few telltale signs:

- Intermittent Functioning: Is your key fob working sporadically? One minute it unlocks your car, and the next, it doesn’t respond at all. This inconsistent behavior is a strong signal that your battery needs replacing.
- Dashboard Warning Light: Some Toyota Highlanders will display a warning message on the dashboard when the key fob battery is low. Keep an eye out for any alerts related to your keyless entry system.
