VAG MQB49 5C Xhorse XSMQB Key Weak Signal Solution

Share the solution regarding the customer’s XHORSE XSMQB smart key weak signal issue.

“Read original MQB49 5C key data ok, but sometimes it doesn’t learn Xhorse XSMQB smart key. Xhorse has a wea signal and since it is keyless you need to disassemble the steering column and pop the Start/Stop button out. Then hold it close to the antenna and make sure the steering wheel is straight. Also use a Faraday Bag and if it still does not work, remove the battery when learning.

Faraday Bag is a small bag which has internal some layer as protected sheet so when you put KeylessGo key inside it will not allow data to come out from bag and you can not start the car. As soon as the key outside from that bag is, you can start the car.

While programming try to keep one key outside so no need to buy the bag

My last skoda even had problem learning back the original key and the remote wouldn work i programmed it like 30 times new until both Xhorse and the original Key worked properly.”

Xhorse Key Tool MIDI Program 2020 Ford Fiesta Smart Key

Adding a spare smart key to a 2020 Ford Fiesta is a straightforward process when using Xhorse VVDI Key Tool MIDI/Key Tool Plus. In this guide, we walk through the steps to add a new key to a Ford Fiesta after confirming that the original key was no longer working.

Step-by-Step Procedure
1. Select the Correct Vehicle Profile

Turn on the ignition and navigate to IMMO Programming- Ford- European- Fiesta- KeylessGo- 2018 onwards.

2. Prepare the Vehicle

The device will prompt you to open and close the driver’s door once, then turn the ignition off. Follow these instructions precisely:

Open the driver’s door and close it.

Switch off the ignition.

Press “OK” on the device to confirm.

3. Back Up the D-Flash

Before adding a key, the system requires you to back up the D-Flash. This step is critical for safeguarding the vehicle’s existing data.

4. Read the Current Number of Keys

The device will read how many keys are currently programmed to the vehicle. In this case, there were two keys already registered.

5. Add the New Key

Select the “Add Key” function. The system will remind you again to back up the D-Flash, which has already been done.

Important: Throughout the entire process, the ignition must remain off. All operations are performed with the ignition switched off.

6. Place the New Key in the Sensing Area

Locate the key sensing area inside the vehicle. In the Ford Fiesta, this area is marked with a key symbol. The presenter had already tested this area by removing the battery from a key, placing it in the sensing spot, and successfully starting the vehicle—confirming the sensing area works even without a key battery.

Place the new smart key in the sensing area and press “OK” on the device.

7. Confirm the Key Count

The device should now display that the current number of keys is three (the original two plus the newly added one). Confirm this is correct.

Testing the New Key

Once programming is complete, test the new key:

Use the new key to start the vehicle.

Then test the original key to ensure it still works.

Both keys functioned correctly after the procedure.

Key Takeaways

• Ignition must be off during the entire key programming process.
• Always back up the D-Flash before adding a key.
• The key sensing area in a 2020 Ford Fiesta is marked with a key symbol and works even if the key battery is removed.
• After programming, verify that both the new and original keys start the vehicle.

This method applies specifically to the 2020 Ford Fiesta using a compatible key programming tool. Always ensure your equipment and software are up to date for the best results.

Xhorse Multi Prog programmer new user review:

Audi A6 C5 cluster swap: cloned via BDM
On this cluster the immobilizer is built in, so the original EEPROM has to move with the car.
Motorola MC68HC912DG128A, read and written over BDM through 4 test points on the board: VCC, GND, BKGD, RESET.

There are already new replacement panels manufactured in 2008-2009, which have a regular backdoor button closed in the software. Only BDM will save them.
