2016 Toyota Tacoma Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

The 2016 Toyota Tacoma allows for on-board programming of the key fob's remote functions (lock, unlock, panic). This procedure will not program the transponder chip required to start the vehicle. For that, a specialized scan tool or a professional locksmith/dealer is required.

Before you begin: Ensure all doors are closed and unlocked. Have all key fobs (working and new ones) you wish to program available. If you only have one working key, the process might be slightly different; these steps assume you have at least one working key.

1. Enter the vehicle and close all doors.
2. Insert the existing, working key into the ignition cylinder. Do NOT turn it.
3. Perform the following sequence within 5 seconds: Insert the key into the ignition cylinder, then remove it. Repeat this two more times (insert, remove, insert, remove, insert, remove).
4. Close and open the driver's door six (6) times. The door must be fully closed and then fully opened each time.
5. Insert the key into the ignition cylinder and leave it there. Do NOT turn it.
6. Close all doors.
7. Remove the key from the ignition cylinder.
8. The power door locks should cycle automatically (lock then unlock) to indicate successful entry into programming mode.
9. Press and hold the LOCK and UNLOCK buttons simultaneously on the new key fob for approximately 1.5 seconds.
10. Immediately after releasing them, press the LOCK button on the new key fob for 1 second.
11. The power door locks should cycle again to confirm successful programming. If you have additional fobs to program, repeat steps 9 and 10 for each fob.
12. To exit programming mode, open any vehicle door.

Battery replacement

The 2016 Toyota Tacoma key fob uses a CR2032 coin cell battery. Replacing it is a straightforward process:

1. Locate the small notch on the side of the key fob casing.
2. Carefully insert a small flat-head screwdriver or a coin into the notch and gently pry the two halves of the fob apart.
3. Remove the old CR2032 battery. Note the orientation of the battery (usually positive side up).
4. Insert the new CR2032 battery with the correct orientation.
5. Snap the two halves of the key fob back together until you hear a click.
6. Test the fob's functions to ensure it's working correctly.

Where to buy a replacement fob

When considering a replacement key fob for your 2016 Toyota Tacoma, you have several options:

• Toyota Dealership: Pros – Guaranteed OEM fit and function, often includes cutting and programming services. Cons – Most expensive option, typically costing $250-$400+ for the fob, cutting, and programming.
• Automotive Locksmith: Pros – Can often provide OEM or high-quality aftermarket fobs, offers cutting and programming services at a more competitive price than dealerships. Many are mobile and can come to you. Cons – Quality of aftermarket fobs can vary; ensure they use reputable brands. Expect to pay $150-$300 for the fob, cutting, and programming.
• Online Retailers (e.g., Amazon, eBay): Pros – Cheapest option for the fob itself, often $20-$60. Cons – You only get the blank fob; you'll still need to pay for cutting the key blade and transponder programming separately. There's a risk of receiving a low-quality or incompatible fob.

If on-board programming isn't supported

While the remote functions of your 2016 Toyota Tacoma key fob can be programmed using the on-board procedure, the transponder chip (immobilizer) inside the key fob, which is essential for starting the vehicle, cannot be programmed this way. This requires specialized equipment.

Immobilizer Transponder: The 2016 Toyota Tacoma uses a G-chip transponder system. This system acts as an anti-theft measure, preventing the vehicle from starting unless the correct transponder chip is present and recognized by the vehicle's immobilizer system. It's not just about turning the key; the car needs to "talk" to the chip.

Cost Expectations: If you need to program a new transponder chip (e.g., for a new key that needs to start the car), you will need the services of an automotive locksmith or a Toyota dealership. Prices typically range from $75-$150 for transponder programming alone, in addition to the cost of the key fob and cutting.
