2000 Toyota Tundra Key Fob Replacement: Simple Programming Steps

Lost or need to replace your 2000 Toyota Tundra key fob? Heading to a dealership can be costly and time-consuming. Fortunately, programming a new key fob for your 2000 Toyota Tundra can be done easily at home with a few simple steps. This guide will walk you through the process, saving you both time and money.

Step-by-Step Guide to Program Your 2000 Toyota Tundra Key Fob

Follow these instructions carefully to program your new key fob. It’s crucial to perform each step accurately and within the specified time frames for successful programming.

Step 1: Initial Setup

Begin with your 2000 Toyota Tundra completely off. Ensure the driver’s side door is open, all other doors are closed, and importantly, the driver’s door is unlocked. Have your new, unprogrammed key fob ready.

Step 2: Initiate Programming Sequence

This step must be completed within 5 seconds:

1. Insert your key into the ignition. Do not turn it.
2. Remove the key from the ignition.
3. Repeat steps 1 and 2 once more. Insert the key into the ignition (do not turn), and then remove it.

Step 3: Door Cycling and Key Insertion

This sequence needs to be done within 40 seconds:

1. Close the driver’s side door, then open it.
2. Close the driver’s side door again, then open it once more.
3. Insert the key into the ignition (again, do not turn) and then remove it.

Step 4: Final Door and Ignition Sequence

This is the final series of actions before programming mode is activated, and must also be completed within 40 seconds:

1. Close the driver’s side door, then open it.
2. Close the driver’s side door again, then open it once more.
3. Insert the key into the ignition and leave it in the ignition cylinder.
4. Close the driver’s door.
5. Turn the ignition to the “ON” position (do not start the engine), and then immediately turn it back to the “OFF” position.
6. Remove the key from the ignition.

Step 5: Programming Mode Confirmation

Within 3 seconds of removing the key in Step 4, listen for your Toyota Tundra’s power door locks. They should automatically cycle (lock then unlock). This lock cycle indicates that you have successfully entered programming mode. If the locks do not cycle, return to Step 1 and repeat the entire process.

Step 6: Key Fob Programming

Now you are in programming mode and can program your key fob within 40 seconds:

1. Press and hold both the “lock” and “unlock” buttons simultaneously on your new remote for approximately 1.5 seconds.
2. Immediately after releasing both buttons, press and hold only the “lock” button for 2 seconds.
3. Within 3 seconds, the door locks should cycle once (lock then unlock) to confirm successful programming of that remote. If the door locks cycle twice, it indicates the remote was not accepted. In this case, repeat steps 6A and 6B.
4. To program additional key fobs, repeat steps 6A and 6B for each new remote.

Step 7: Exit Programming Mode

Open the driver’s side door to exit the programming mode. Your newly programmed 2000 Toyota Tundra key fob should now be functional.

This straightforward method allows you to handle your 2000 Toyota Tundra Key Fob Replacement efficiently and avoid unnecessary dealership expenses. By following these steps, you can quickly regain the convenience of remote locking and unlocking.
