Lonsdor K518 Pro Add 2023 Toyota Tundra Key via LT20

 The article shows a user-friendly process of programming a new smart key for a 2023 Toyota Tundra using Lonsdor K518 Pro and Lonsdor LT20 smart key.

The first step in the process involves accessing the vehicle’s 30-pin diagnostic port. On the Toyota Tundra, this port is conveniently located behind a panel on the driver’s side lower dashboard. We used a simple panel tool to quickly pop off the cover without needing to remove any screws, revealing the necessary plug. Then connect FP-30 30 pin connector.

1.Back up IMMO Data

Go to IMMO & Remote- Toyota- Select from vehicle- USA- Tundra- 2021 up- Smart  Key- PEPS- Back up IMMO Data

Save immo data.

2. Generate LT20 smart key

3.Add Smart Key

Load the D-flash data of PEPS to acquire 12-digit PIN code.

Done.

How to Add 2013 Citroen Jumper Key with Lonsdor K518 Pro?

 We’re working on a 2013 Citroen Jumper. A customer need to add a spare key. We are going to add a key using Lonsdor K518 Pro.

In these vehicles, the keys are stored in the BCM, and there are two modules—Magnetti Marelli and Delphi. Each module has its own nuances, and each module requires its own keys (despite their external similarity).

Since the blade of the old key remains and only the circuit board was damaged, the recovery process is somewhat simplified. Here’s the recovery procedure:
1. Read the necessary information from the key block.
2. Using this information, generate a so-called dealer key.
3. Program each key to the vehicle.

Working time: 30 minutes.

Below are photos of the process.

How to Add Chevy Tahoe 2016 Smart Key with Lonsdor K518 Pro?

 How to add a spare smart key to a Chevrolet Tahoe, manufactured in June 2016 using Lonsdor K518 Pro?

These vehicles are often considered 2017 models, as the sixth month is a transitional year for American cars. If the year is a transitional year, the programming procedure and even the key type may differ significantly.

However, in our case, it’s quite simple—regardless of whether this Tahoe is considered a 2016 or 2017. Dealer tools are not required, but a programmer with immobilizer support is still required.

 

Step 1: Read Pin Code

Select IMMO & Remote- Chevrolet- USA/Canada-Tahoe- 2017 to 2019 -Smart key- Read PIN Code.

Read 4-digit pin code successfully.

Step 2: Add smart key

If select Add smart key from this menu path, Lonsdor will report an error Security access verification failed.

An interesting challenge arose regarding the model year. We initially selected 2016 but encountered a communication error. Switching to the previous model year (likely 2015 for this “transitional” 2016 vehicle) resolved the issue immediately. This serves as a vital tip: if you encounter an error when programming a GM vehicle, trying an adjacent model year is a practical first step.

Select Chevrolet- USA-Tahoe-2015 to 2016 year- Program smart key- Add smart key.

Turn on igntion switch.
Put the smart key to be programmed into the key slot, take other keys ourside the car.

The slot here is under the cup holder.
Read current key numbers.

Enter 4-digit pin to access.

Lonsdor k518 pro starts 10-minute configuration of the system process.

The new key was programmed successfully.

Hold down the start button for 12 sec.
Release the start button and wait for 5 sec.

Press and hold the start button until the dashboard turns on.

Press the start button to switch ignition off.
Open and close the driver’s door.
Configuring system.

Key programming is completed.
