OBDSTAR Program 2024 Toyota Tacoma All Smart Keys Lost

 This guide demonstrates how to perform an “All Keys Lost” procedure on a 2024 Toyota Tacoma with push-button start using the OBDSTAR. The process involves generating a new smart key, programming it via the vehicle’s smart box, and troubleshooting remote functionality.

 

Tools Required

• OBDSTAR X300 Classic G3/X300 DP Plus

• Toyota 30 PIN bypass cable

• Lonsdor KW100 (for key generation)

• Blank smart key. Here use Lonsdor LT20 smart key (compatible with Toyota’s proximity system)

 

 

Step-by-Step Process

1. Generating a New Smart Key

• Connect the Lonsdor KW100 to the Tacoma’s OBD port.

• Select “All Keys Lost” mode and place the blank key near the smart start button.

• Press the brake pedal to allow the system to read vehicle data.

• The device generates a new key based on the vehicle’s immobilizer information.

2. Accessing the Smart Box

• Locate the smart box (typically behind the dashboard or center console).

• Disconnect the factory wiring harness and connect the OBDSTAR Toyota 30 PIN bypass cable to read “immo data” (immobilizer data).

3. Reading & Writing Immobilizer Data

• Select Toyota > Tacoma (2024) > Proximity System in the OBDSTAR.

• Choose “Read Immo Data” to extract the necessary immobilizer information.

• Reconnect the original smart box harness before proceeding.

4. Generating a Simulator Key

• The OBDSTAR generates a temporary simulator key to bypass immobilizer checks.

• Test the simulator key—the vehicle should power on (though remote functions may not work yet).

5. Add smart key

• Turn ignition ON with the emulator key.

• Select immo data has been backed up and read pin code to program key.

• Wait for confirmation beeps (two beeps indicate success).

• Test the key.
