Keydiy KD-X4 Program 2021+ Ford BCM R7F701053 Key without PIN

Apr23

Keydiy KD-X4 key programmer will release new Ford Immobilizer software soon-supports 2021+ Ford key programming by reading BCM module data. Keep an eye on the software upgrades.

Here is an example of adding a spare key on a 2022 Ford Mustang Mach-E using KD-X4. Keydiy will do both add key and all key lost. All keys lost share the same procedure.

The same produre goes to 2021-Ford F-150, Focus, Bronco, Mondeo, EVOS etc.

BCM: R7F701053 or R7F701073

This function requires removing BMC module and back up immo data first.

The BCM is located on the passenger side of the vehicle.

Remove the BCM module

Connect the BCM and the KD-X4 MCU cable according to the wiring diagram

Connect Keydiy KD-X4 with tablet or phone via OTG connector

Go to IMMO programming function
Select KD-X4 device-Programmer function
Select Read file function
Choose Ford-BCM R7F701053 or R7F701073

Read and save BCM data

Reinstall BMC module back to vehicle and add key in car

Select IMMO programming-Ford-select by type-Keyless System-Type 35-Add key or All keys lost.

Follow KD-X4 App prompts to add a spare key.

How to Fix FormulaFlash No Power in Bench Mode (LED Not Lighting Issue)

Apr22

A customer recently reported the following issue with their FormulaFlash ECU Programmer

“My device stopped providing power in bench mode. The LEDs no longer light up. Is there any chance of repairing it? It is still under warranty.

After inspection, the root cause was identified as a burnt FB0 resistor on the PCB board, which resulted in a complete loss of power output in bench mode.

Root Cause Analysis
The failure is typically caused by:

  • Overcurrent or incorrect wiring during bench operation
  • Short circuit during ECU connection
  • Component aging or unexpected voltage spikes

The damaged component (FB0 resistor) plays a key role in the power circuit. Once it is burnt, the device will:

  • Fail to supply power in bench mode
  • Show no LED activity
  • Appear completely unresponsive

Repair Solution
Method 1: Replace with a 0 Ohm Resistor
The recommended solution is:

  • Replace the damaged FB0 component with a 0Ω (zero-ohm) resistor

This acts as a jumper and restores the circuit continuity.


Method 2: Use a Donor Resistor from the PCB
If a 0Ω resistor is not available, you can:

  • Locate a row of similar resistors on the PCB board
  • Remove one resistor from that row
  • Solder it onto the burnt FB0 position

Important Notes

  • This repair requires basic PCB soldering skills
  • Improper handling may cause further damage
  • If your device is still under warranty, it is recommended to contact your supplier before attempting repair

Preventive Tips
To avoid similar issues in the future:

  • Double-check wiring before powering the device
  • Use stable power supply during bench operations
  • Avoid hot-plugging ECU connections
  • Ensure proper grounding

Conclusion
A FormulaFlash device that shows no power in bench mode and no LED activity is often caused by a burnt FB0 resistor. Replacing it with a 0Ω resistor or using a donor component from the PCB can effectively restore functionality.

If you are unsure about the repair process, always consult technical support or refer to the official documentation

Keydiy KD-X4 Now Will Modify Original VAG MQB49 5C 5D Key ID !!!

Apr14

Good News for everyone- the KEYDIY KD-X4 key programmre can modify the ID of original factory VAG MQB49 5C and 5D keys.
. In previous versions, the KD-X4 could only change the ID of the KD’s own 5C/5D keys. With latest update, the KD-X4 can also change the ID of original keys.

Fairly new update within the past few days.

Changing the original key ID will take 100 coins each time.


Example:

Done a VW ID.3 2021 MQB49 5D key. Changed factory key ID. Cost 100 coins to do. No SFD lock, 5D done today for ID.3 2021, changed factory key, cost 100 coins to do.

Used OEM board, second hand from ebay. Worked a treat, carefully split case, then glued together and reassembled. No one will even know. It does cost 100 coins to rewrite original board ID, but did the job.

To be fair KD FGB would be better option with the wireless remote generation. Without KD solderless adapter, you have to solder wires on the origina key.

NOTE:
Modify the ID of KD’s FGB remote does not require points.
CGDI K2 and YANHUA ACDP will also modify OEM 5C/5D key ID.

OBDSTAR MB FBS3/FBS4 TCM OBD Virginization First to Launch !

Mar4

Breaking update news 
MB FBS3/FBS4 TCM OBD Virginization
First-to-Launch! No Risk!
OBDSTAR X300 Classic G3 AND DC706

Support Functions

  • Virginization
  • Write yN
  • Personalization (Data Transfer)

Function Background
When replacing a used Mercedes-Benz TCU, the interna immobilizer data must be erased before installation. Only after virginization can the unit be installed and programmed online
or undergo personalization transfer by using the original diagnostic tool.

1.Drawbacks of Traditional Open-Cover & Soldering

Methods :
At present, the market only allows destructive operations
on FBS4 (VGS4-0-NAG2)7-speed TCM units through cutting or soldering
These procedures are complex and carry extremely high risk of module damage. They also require highly skilled techniciansAny operational error may result in irreversible damage and significant financial loss.

2. Advantages of the New OBD Virginization Solution:

  • No cutting. No soldering

Through OBD or BENCH mode, used FBS3 (VGS2 /VGS3-NAG2) andFRSA/CSA-0_NACD) CVs can oe restoreo to factory- original (virgin) condition, after reading the original vehicle ECU data and completing personalization, no additional online programming is required.
Install the module and start the vehicle immediately-significantly improving workshop efficiency while eliminating operational risk
