For owners of the 2021 Toyota Tacoma, maintaining your key fob is crucial for seamless vehicle access and operation. Understanding the components of your key fob, especially the 2021 Tacoma Key Fob Battery Size, is essential for timely maintenance and replacements. This guide provides you with the necessary information regarding your 2021 Tacoma key fob, ensuring you stay informed and prepared.
When it comes to replacing your 2021 Tacoma key fob battery, the size you’ll need is a CR2032 battery.

It’s important to note that for the 2021 Toyota Tacoma, there are two key fob options available, although both utilize the same CR2032 battery size. To ensure you are selecting the correct replacement remote if needed, understanding these options is vital.

How to Determine Which Option is Right for Your Tacoma:
The most reliable way to determine which key fob option is correct for your 2021 Toyota Tacoma is to contact your local Toyota dealership. Provide them with your vehicle’s VIN (Vehicle Identification Number), and they can verify the exact part number for your original key fob. This ensures you get the correct replacement if needed.
Replacing Your 2021 Tacoma Key Fob Battery
As mentioned, both key fob options for the 2021 Toyota Tacoma use a CR2032 battery. Replacing this battery is a straightforward process that you can typically do yourself. You will need a small flathead screwdriver to gently pry open the key fob casing. Once open, you can easily access and replace the CR2032 battery. Ensure you install the new battery with the correct polarity (+ side up).
While replacing the battery is simple, programming a new or replacement key fob to your 2021 Toyota Tacoma is not. Professional programming is required. This means you will need to visit a Toyota dealership or a qualified automotive locksmith to have the new remote programmed to work with your vehicle’s immobilizer system. The emergency insert key included with aftermarket remotes also needs to be cut by a professional to match your vehicle’s ignition.
Key Fob Features and Important Considerations
Your 2021 Toyota Tacoma key fob is designed for vehicles equipped with a push-to-start ignition system. It typically features three buttons: Lock, Unlock, and Panic alarm, providing essential remote functionalities.
When purchasing a replacement key fob, ensure it is a genuine OEM (Original Equipment Manufacturer) remote for guaranteed compatibility and reliability. Aftermarket options are available, but OEM remotes are recommended for optimal performance.
Remember, key fobs are reusable. Used remotes can be unlocked and reflashed, making them viable options for locksmiths and dealers. However, for end-users, purchasing a new, tested remote is usually the most convenient solution.
For professional programming services, you can use resources like Locksmith Search to find a qualified automotive locksmith in your area.
By understanding your 2021 Tacoma key fob battery size, the available options, and the necessity of professional programming, you can confidently maintain your vehicle’s keyless entry system and ensure uninterrupted access and operation.
