K518 Software update: New Function for AKL of Toyota/Lexus by OBD data back-up

Good news!!! Lonsdor updated the latest software, and the Toyota AKL Online Calculation software license added the OBD function!!!

What does this mean? It means that customers who purchase this software can use this function for free!!

But if you have Lonsdor ADP 8A/4A adapter, you don't need to buy this software license, their functions are the same.

The difference between them:

1. ADP 8A/4A adapter is hardware, and Toyota AKL online calculation is software.

2. Different ways to do Toyota All Key Lost

For K518 + ADP, the smart box needs to be removed, which takes a lot of time and work.

For K518 + Toyota AKL Software, no need to remove the smart box, saving effort and time.

3. Expiration date

ADP can be used for life after purchase (provided the product is not damaged).

Toyota AKL software package is only valid for one year after activation, if you want to continue using it in the second year, you need to reactivate it.

Fixed: Lonsdor KH100+ Can't Identify PH0440B "No chip detected"

Problem: The Lonsdor KH100+ is unable to identify PH0440B Smart Key, it says: "No chip detected, probably it's placed improperly". It keeps failing even I take off its key shell and try different positions. 

What should I do, any ideas?

Solution

Try the steps if the indicator can flash when pressing a key button.

1.Try the menu to check if KH100+ can read key info: Special functions >> FT Smart Key >> 8A type >> Get version info;

2. Upgrade Lonsdor KH100 Plus programmer;

3. Upgrade PH0440B key: Special functions >> FT Smart Key >> 8A type >> Upgrade Smart Key 

Now you can go back "Identify and copy" menu to try again.

The problem can be solved.

How to Test Lonsdor K518ISE OBD Cable & Connection Chip?

Problem: I've tried to connect my Lonsdor K518ISE to Land Rover, Ford & Audi, but they all have the same error: "Vehicle connection failed, please check the connection between the device and vehicle OBD."

Possible reasons that may cause the issue:

1. OBD cable is broken;

2. K518 communication chip is damaged.

Test with a new OBD cable to judge if the communication chip can still work normally. To find out if the OBD cable has a problem, we need to test it.

How to test K518 OBD cable?

1. Unplug K518 Key Programmer and turn it off.

2. Connect the OBD cable(DB25 cable) to K518ISE, and switch to the diode stalls with a multimeter.

Pay attention that there are 3 connectors on the OBD cable:

Connector 1: connect K518ISE OBD port;

Connector 2: connect KPROG adaptor;

Connector 3: connect the vehicle OBD port.

3. Touch the metal part(shown in pic) with a red pen.

4. Test the resistance of each pin on the K518 connector with a black pen, making sure the vehicle connector is held in the way as shown.

PIN1,8 should have no resistance;

PIN2,3,4,5,6,7,9,10,11,12,13,14,15,16 should have resistance.

Test Results

If all have no resistance, the OBD cable(DB25 cable) has a problem.

If the measurement is all as it is supposed to be, and the car(K518 supported models) still can't be connected, you'll need to send back the OBD cable(DB25 cable) & K518 device for Lonsdor to check.

Solved: Lonsdor K518ISE Adds JLR Key Keyless Not Working

Problem: I added a new Lonsdor JLR Key to a Land Rover Discovery 2018 with a K518ISE Key Programmer. All buttons open, close & boot work fine. But Keyless not working on your keys. Only I can start the car if I put the key to the emergency point on the car.

What's the problem? Please advice.

Solution

In case remote & emergency work fine but without a keyless function, it needs to close the UWB function.

How to close UWB in Lonsdor K518?

Immo & Remote >> Land Rover >> Select from vehicle >> Land Rover(2018-) >> Smart Key >> Modify vehicle cofig >> Close UWB

Note: 

Please be sure to open the Lonsdor JLR License before programming add key & all keys lost for 2015-2020 Jaguar/ Land Rover.
