For models from 2016 onwards, the battery compartment might be located on the inside of the key fob, near the bottom. You’ll need to use a tiny flathead screwdriver or a small tool to carefully pry the compartment open. Be cautious not to damage any of the internal components.
If you’re still having trouble finding the battery compartment, consult your owner’s manual or contact a Toyota dealership for assistance.

Choosing the Right Replacement Battery for Your Toyota Key Fob

When it comes to replacing the battery in your Toyota key fob, it’s essential to choose the right one to ensure proper functionality and avoid any potential issues. Selecting the wrong battery can lead to problems such as a non-responsive key fob, erratic behavior, or even complete failure.
There are several options available in the market, including Original Equipment Manufacturer (OEM) batteries and aftermarket alternatives. OEM batteries are designed and manufactured by Toyota itself, while aftermarket batteries are produced by third-party companies.
Original Equipment Manufacturer (OEM) Batteries
OEM batteries are the gold standard when it comes to key fob batteries. These batteries are specifically designed for Toyota’s key fobs and are guaranteed to meet the manufacturer’s standards. They are usually more expensive than aftermarket batteries, but they are the best option for those who want a hassle-free experience.
Some reliable OEM battery suppliers include:
- Toyota’s official website or dealership centers, which usually carry the genuine OEM keys and fobs.
- Some well-reputed auto part suppliers and wholesalers, such as O’Reilly Auto Parts or Autozone.
Prices for OEM batteries can vary depending on the supplier and shipping location, but you can expect to pay anywhere from $10 to $25 for a single key fob battery.
Aftermarket Batteries
Aftermarket batteries are designed to meet the same specifications as OEM batteries but at a lower price point. These batteries are usually produced by reputable manufacturers such as Energizer, Panasonic, or Rayovac. While they may not offer the same level of quality as OEM batteries, they can be a good option for those on a budget.
When choosing an aftermarket battery, it’s crucial to select one that is compatible with your Toyota key fob. Look for batteries with a voltage and amperage rating that matches the specifications of your key fob.
Some reliable aftermarket battery suppliers include:
| Supplier | Price Range | Shipping Time |
|---|---|---|
| Energizer | $5-$15 | 3-5 days |
| Panasonic | $7-$18 | 2-4 days |
| Rayovac | $8-$20 | 2-3 days |
It’s essential to use a high-quality battery that meets Toyota’s specifications to ensure optimal performance and longevity. Using a battery that is not designed for your key fob can lead to premature wear and potentially cause damage to the fob or other components.
Always read reviews and consult with the manufacturer before making a purchase to ensure that you are getting a high-quality battery that meets your needs.
