Experiencing issues with your 2019 Toyota Highlander key fob can be frustrating, especially when you assume a simple battery replacement will solve the problem. Like many, you might think a dead battery is the only culprit when your key fob stops working. However, sometimes the issue goes beyond just needing a new battery.
Common Key Fob Battery Problems
Typically, when your Toyota Highlander key fob weakens or fails, the first step is to replace the CR2032 battery. This is a straightforward process, and for most common key fob malfunctions like decreased range or intermittent operation, a fresh battery resolves the issue. You can usually find these batteries at any drugstore or online, and changing them is a quick DIY task.
When a Battery Change Isn’t Enough: The Unpairing Problem
But what happens when you replace the 2019 Toyota Highlander Key Fob Battery, and it still doesn’t work? This is where things can get a bit more complex. In rare cases, like one Toyota owner experienced, the key fob can become inexplicably “unpaired” from the vehicle. Imagine changing your key fob battery only to find your Highlander doesn’t recognize it anymore – the doors won’t unlock, the panic button is unresponsive, and the vehicle won’t start with the key fob.
This situation can leave you scratching your head, especially if you’ve never encountered it before. The owner in question initially suspected a faulty new battery or a more serious fob malfunction. However, after seeking professional help, they discovered the surprising truth: the key fob itself was still functional, but it had somehow lost its connection to the Highlander’s system.
Reprogramming Your Key Fob: A Simple Solution
The good news is that an “unpaired” key fob doesn’t necessarily mean you need a costly replacement. Often, the solution is relatively simple: key fob reprogramming. Specialized services, like those offered at Batteries Plus or certain locksmiths and auto parts stores, can re-establish the communication between your 2019 Toyota Highlander and your existing key fob.
This process involves using diagnostic tools to essentially “re-introduce” your key fob to your vehicle’s computer system. It’s similar to pairing Bluetooth devices – you’re essentially re-syncing the fob and the car. In the anecdote, the owner was able to get their original fob reprogrammed, avoiding the expense and potential wait time of ordering a new one, especially relevant given chip shortages that can impact key fob availability.
Where to Seek Key Fob Reprogramming Services
If you find yourself in this situation after changing your 2019 Toyota Highlander key fob battery, don’t panic. Here are some places you can explore for reprogramming services:
- Batteries Plus: As mentioned, they offer key fob testing and reprogramming services.
- Local Locksmiths: Many locksmiths specialize in automotive key services, including reprogramming.
- Auto Parts Stores: Some larger chain auto parts stores may offer key fob programming.
- Toyota Dealership: While potentially more expensive, your Toyota dealership can definitely handle key fob reprogramming.
Before assuming you need a new key fob, consider getting your existing one checked and potentially reprogrammed. It could save you time and money and get you back on the road quickly with your 2019 Toyota Highlander.
