Gaining control over your vehicle’s access and security is paramount, and having a properly programmed remote key fob is a significant step in achieving that. This guide offers a detailed walkthrough on how to program a remote for your 2016 Toyota Highlander. We’ll cover various methods, potential issues, and troubleshooting tips, ensuring you can confidently manage your vehicle’s remote functionalities.
Understanding Your 2016 Toyota Highlander Remote System
Before diving into the programming process, it’s essential to understand the key components and features of your 2016 Highlander’s remote system. This includes knowing what type of remote you have, the functionalities it offers, and the security features associated with it.
Types of Remote Key Fobs
Your 2016 Highlander likely uses one of two types of remote key fobs: a standard key fob with buttons or a smart key fob (also known as a proximity key). The standard key fob typically has buttons for locking, unlocking, and possibly a panic alarm. The smart key fob, on the other hand, allows for keyless entry and push-button start, requiring only proximity to the vehicle. Identifying which type you have is crucial for selecting the correct programming method. Always verify your key fob type before proceeding.
Functionalities and Features
The standard remote provides basic functionalities like remote locking and unlocking of doors, and a panic alarm.

Understanding these features allows you to confirm the success of the programming process after each step. Test all functionalities after programming.
Security Considerations
Modern remote key fobs are designed with security in mind. They use rolling codes that change each time the remote is used, preventing replay attacks. During programming, you are essentially teaching the vehicle’s computer to recognize the unique identifier of your remote. Keep in mind that unauthorized programming can compromise your vehicle’s security. Protect your vehicle from unauthorized access.
Programming Your Remote: A Step-by-Step Guide
Several methods can be employed to program your 2016 Toyota Highlander remote. We will primarily focus on the most common DIY method, which is the on-board programming procedure. It is crucial to follow these steps precisely for a successful outcome. Read the entire section before attempting any programming.
On-Board Programming Procedure
This method is suitable for adding or re-programming remote key fobs if you already have one working key. If you have lost all keys, you may need to consult a professional locksmith or dealership.
- Ensure all doors are closed and unlocked. This sets the stage for the programming sequence.
- Insert your existing, programmed key into the ignition. Turn the key to the “ON” position (do not start the engine).
- Cycle the key between the “ON” and “OFF” positions rapidly five times. On the fifth cycle, leave the key in the “ON” position. The doors should automatically lock and unlock, indicating that the vehicle has entered programming mode.
- Open and close the driver’s side door once for adding a remote, twice for erasing all remotes. In this case, we’re adding a remote, so open and close the door once.
- Press any button on the new remote you wish to program. The door locks should cycle again to confirm that the remote has been successfully programmed.
- If you have additional remotes to program, repeat steps 4 and 5 within 40 seconds for each remote. This allows you to program multiple remotes in a single session.
- Remove the key from the ignition. The doors should lock and unlock one last time to confirm that the programming is complete.
Testing the Programmed Remote
After completing the programming procedure, it’s imperative to test all the remote’s functionalities to ensure it has been properly programmed. This includes the lock, unlock, and panic alarm buttons. For smart key fobs, test the keyless entry and push-button start functions. Thorough testing is essential.
