OBDSTAR G3 Replace Renault Logan 2012- BCM UCH

How to replace Dacia Sandero 2013-2019 Continental UCH with JCI using OBDSTAR X300 Classic G3. It is similar to older Renault/Dacia cars.

 

NOTE: You will need G3. X300 DP Plus does not have ECU advanced function.

This may not work on every Renault/Dacia. Always check G3 coverage and function before operation.
Read original UCH information.

Go to ECU Advanced- Renault/Dacia->BCM/UCH
Drop down list and find Logan-> 2012 onwards-> Continental

Read ECU info.
OBDSTAR will read part number, VIN, keys, etc info.

You can read Dflash and extract a PIN code from the BCM / UCH memory.

If failed to read pin code under ECU Advanced function, try to extract pin code via method 2 here.

Autel tools are used to be able to change UCH VIN for these Renault. But it no longer reads pin code.

 

Once you get the pin code. Replace the Continental UCH with the JCI one.

Drop down list and find Logan-> 2012 onwards-> Johnson

 Here obdii365.com introduces two ways to add a blade key to Renault Kadjar 2018-2019 using OBDSTAR X300 Classic G3 or x300 dp plus via OBD.

 

Procedure:

Decode and cut Renault VA2EH2 key blade with Xhorse Dolphin XP005L.

Way 1 without risk

Read immo information.

It takes 1-10 minutes to read pin code.

After read pin code, then perform make dealer key and program key procedures.

 

 

Way 2 risky.

Here we use risky method 2.

Here is a dangerous method with extracting a pin code directly from the BCM / UCH memory. If time allows, it is better to use a safe method.

Select Risk way.

Read immo information as well.

Select Read Dflash.

Turn ignition off.

Read the OBDSTAR caution on this vehicle.
The key will be erased during the process of reading Dflash.

There will be the risk of reading failure because of no pin code in UCH of very few models. After reading the Dflash, must perform All Keys Lost to program keys.

Must have stable network connection and extra power supply.

Deleting key.

Read Dflash and save data.

Select All keys lost function.

Select Make dealer key.

Choose Dflash just saved.

OBDSTAR G3 will extract pin code from the UCH dflash dump.

Put the new key in the key sensing coil.
