Program 2012 Toyota Sienna All Keys Lost with Xhorse VVDI Key Tool Max Pro

This guide provides a step-by-step walkthrough for performing an “all keys lost” procedure on a 2012 Toyota Sienna using the Xhorse VVDI Key Tool Max Pro. The process involves retrieving the door lock code, cutting a new key, programming the transponder chip, and syncing the remote control.

 

 

Tools

Before starting, ensure you have the following:

• Xhorse VVDI Key Tool Max Pro

• Xhorse Dolphin XP005 software (connected via hotspot or internet)

• M5 clamp for key cutting

• Blank key (ensure it has the correct transponder chip, e.g., G-chip or A-chip)

• Screwdriver (for removing the door lock cylinder)

 

Step 1: Retrieve the Door Lock Code

The Toyota Sienna’s door lock cylinder contains a 5-digit mechanical code required to cut a new key. Here’s how to find it:

1. Locate the Door Lock Cylinder:

   • The cylinder is typically on the driver’s side door but may also be on the passenger side.

   • Remove the door panel if necessary to access the cylinder.

2. Remove the Cylinder:

   • Unscrew the retaining bolt holding the cylinder in place.

   • Carefully extract the cylinder from the door.

3. Identify the Code:

   • Inspect the cylinder for stamped numbers.

   • There may be two codes: ignore the one starting with a letter (e.g., X238) and use the 5-digit code (e.g., 52769).

   • If the code isn’t visible, check the passenger-side cylinder.

Step 2: Cut the New Key

Using the retrieved code, cut a new key with the Xhorse Dolphin XP005:

1. Connect the Device:

   • Launch the Dolphin app on your phone or device.

   • Ensure you have an active internet connection (hotspot recommended).

2. Enter the Code:

   • Navigate to All Key Lost > Toyota and input the 5-digit code.

   • Double-check the code for accuracy (e.g., 52769).

3. Cut the Key:

   • Place the blank key in the M5 clamp (position 3 or 4).

   • Follow the on-screen prompts to cut the key.

   • Verify the key fits the ignition and door locks.

Step 3: Program the Transponder Chip

The 2012 Toyota Sienna uses either a G-chip or A-chip. Here’s how to program it:

1. Turn the Ignition On:

   • Insert the newly cut key and turn the ignition to the “ON” position.

2. Select the Correct Chip:

   • On the Key Tool Max Pro, navigate to Toyota > Sienna > Flip Key.

   • Test the G-chip first (common for this model).

     • If communication fails, try the A-chip.

3. Follow Programming Steps:

   • Select All Programming > Reset All Keys Lost.

   • The device will prompt you to:

     • Insert the key and turn the ignition on.

     • Remove the key and wait 5 seconds.

     • Reinsert the key (do not turn it on).

   • If successful, the security light will flash and then turn off.

4. Add a Second Key (Optional):

   • Repeat the process for a spare key if available.

Step 4: Program the Remote Control

To sync the key’s remote functions (lock/unlock):

1. Enter Remote Programming Mode:

   • Exit the transponder programming menu and select Remote System > Common > Remote Adding.

   • Ensure the passenger door is open and the ignition is on.

2. Sync the Remote:

   • Press and hold Lock + Unlock together for 1 second, then release.

   • Immediately press the Lock button repeatedly until you hear a confirmation beep.

   • If unsuccessful, retry the steps or test another remote.

3. Verify Operation:

   • Test the remote to confirm it locks/unlocks the doors.

 

Troubleshooting Tips

• Code Not Found: If the door cylinder code is missing, check the passenger side or consult a dealership for assistance.

• Programming Fails: Ensure the correct chip type is selected (G-chip is most common for 2012 Sienna).

• Remote Issues: Replace the remote battery or try a different remote.
