2017 Toyota Tacoma Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

Good news! The remote functions (lock, unlock, panic) for your 2017 Toyota Tacoma key fob can be programmed yourself. This procedure will not program the immobilizer transponder chip, which is required for the vehicle to start. That requires specialized equipment.

To program the remote functions:

1. Start with all doors closed, and the driver's door open and unlocked.
2. Insert the key into the ignition and remove it TWICE within 5 seconds.
3. Close and open the driver's door TWICE within 40 seconds.
4. Insert the key into the ignition and remove it.
5. Close and open the driver's door TWICE within 40 seconds.
6. Insert the key into the ignition.
7. Close the driver's door.
8. Turn the ignition to ON and then back to OFF. Remove the key. You should hear the power door locks cycle once.
9. On your new key fob, press and hold the LOCK and UNLOCK buttons simultaneously for 1.5 seconds. Release both buttons.
10. Immediately after releasing, press and hold the LOCK button for 1 second. Release the button. The power door locks should cycle once to confirm successful programming.
11. If you have additional fobs to program, repeat steps 9 and 10 for each fob within 40 seconds.
12. After programming all fobs, open the driver's door to exit programming mode.

Battery replacement

Replacing the battery in your 2017 Toyota Tacoma key fob is a simple DIY task. All you'll need is a small flathead screwdriver and a new CR2032 battery.

1. Remove the emergency key: Press the small button on the side of the fob and pull out the emergency key blade.
2. Pry open the case: Carefully insert the flathead screwdriver into the notch where the emergency key was removed. Gently twist the screwdriver to separate the two halves of the fob casing.
3. Replace the battery: Note the orientation of the old battery (CR2032) before removing it. Insert the new CR2032 battery with the positive (+) side facing up.
4. Reassemble: Carefully align the two halves of the fob casing and press them together until they click securely. Reinsert the emergency key blade.

Where to buy a replacement fob

Finding a replacement key fob for your 2017 Toyota Tacoma gives you a few options, each with its pros and cons:

• Toyota Dealership: This is the most reliable option for genuine OEM parts. You're guaranteed a compatible fob, and they will typically handle both cutting the emergency key and programming the immobilizer transponder. However, it's usually the most expensive route, potentially costing $250-$400 or more for the fob, cutting, and programming.
• Automotive Locksmith: A qualified automotive locksmith can provide and program a new key fob for your Tacoma. They often have access to OEM or high-quality aftermarket fobs and the specialized equipment needed for immobilizer programming. Locksmiths are generally more affordable than dealerships, with costs typically ranging from $150-$300, including the fob, cutting, and programming.
• Online Retailers (e.g., Amazon, eBay): You can often find aftermarket key fobs online for a significantly lower price, sometimes as low as $30-$70. Be sure to verify the FCC ID (HYQ12BDM) and part numbers to ensure compatibility. The major drawback here is that these fobs usually come ungut, and you'll still need to pay a locksmith or dealer to cut the emergency key blade and program the immobilizer transponder, adding to the overall cost. If you purchase an aftermarket fob, ensure it explicitly states compatibility with your vehicle and includes the necessary transponder chip.

If on-board programming isn't supported

While the remote functions of your 2017 Toyota Tacoma key fob can be programmed yourself, the immobilizer transponder chip, which is crucial for starting your vehicle, cannot be programmed without specialized diagnostic equipment.

This means that even if you buy an aftermarket fob online and program the remote functions yourself, your vehicle still won't start until the transponder chip is programmed to your Tacoma's immobilizer system. This requires either a Toyota dealership or an automotive locksmith with the appropriate scan tools.

Cost expectations for immobilizer programming:

• Dealership: Expect to pay for their labor rates, which can range from $100-$200 or more just for the programming service if you bring your own fob.
• Automotive Locksmith: Locksmiths typically charge $75-$150 for immobilizer programming services, often included if they are providing the fob as well.

Toyota Tacomas use a "G" or "H" chip transponder system. It's essential that any replacement key fob you purchase contains the correct transponder chip for your vehicle to function properly.
