Lonsdor K518 Pro Add 2022 Toyota Tundra Smart Key with 30 PIN Cable

 We recently worked on a 2022 Toyota Tundra, adding a smart key to the vehicle using the Lonsdor K518 Pro and an Xhorse XM38 Universal Key. This process is a great example of how modern key programming tools can provide efficient solutions, even when the original key is unavailable.

The Challenge

The customer’s original smart key had been damaged after going through the washing machine. While a replacement key was on order, we decided to create a backup key using the Xhorse XM38 Universal Key. This universal key is a versatile solution for situations where the original key is not immediately available.

 

Tools Used

• Lonsdor K518 Pro: A powerful key programming tool.
• Toyota 30-pin Cable: Specifically designed for Toyota vehicles.
• Xhorse XM38 Universal Key: A universal smart key that can be programmed for various vehicles.
• VVDI Mini key tool: Used to generate the correct key data.

 

Step-by-Step Process

Accessing the Smart Box

1. The first step was to access the vehicle’s smart box. The 2022 Toyota Tundra has a small panel that can be easily snapped off by hand. Inside, there are three connectors, with the smart box located in the middle. The top plug is the one we needed to connect to the Lonsdor K518 Pro using the Toyota 30-pin cable.

Reading and Saving the Data

1. After connecting the Lonsdor K518 Pro to the vehicle’s OBD port, we read the vehicle’s data and saved it as a backup file. This file was named using the last four digits of the VIN (Vehicle Identification Number) for easy reference. This step ensures that we don’t need to rely on third-party services for rolling codes or other data.

Adding a New Smart Key

1. With the data backed up, we proceeded to add a new smart key. Since the customer already had one working key, we didn’t need to perform an “all keys lost” procedure. Instead, we used the Lonsdor K518 Pro to add the new key to the system. The process involved:
   • Loading the D-flash data to acquire a 12-digit PIN code.
   • Placing the original key near the ignition to get one beep.
   • Placing the new key near the ignition to get two beeps.
2. Successful Key Addition
   After a quick processing period, the new key was successfully added to the vehicle’s system. The 2022 Toyota Tundra can store up to five keys, and now the customer has three keys programmed: the original, the Xhorse XM38 Universal Key, and the replacement key that will be installed later.

Why Use a Universal Key?

The Xhorse XM38 Universal Key is an excellent temporary solution, especially when the original key is unavailable. In this case, the customer was interested in keeping the universal key, but we recommended waiting for the original-style key to arrive. The universal key ensures that the customer isn’t left stranded, especially since they work in emergency rescue and need reliable access to their vehicle.
