Xhorse Universal Remote and Keydiy Remote Comparison

Here comes the berif comparison between Xhorse universal remote and Keydiy KD universal remote.

 

 

 

Xhorse has its remotes very well organised. This makes finding remotes for a vehicle and its generation simpler. The super chip/remote enables wide chip coverage.

KeyDIY is still excellent value, it can generate some remotes not supported on Xhorse (e.g., Alfa, Jaguar, VW).

 

Better keep both Xhorse and KeyDIY, in case one does a remote that another couldn’t do. They have their own pros and cons. KeyDIY has extensive coverage of remotes. They usually cost way cheaper than original remotes. It is good to back a cloning/chip generation backup tool when the server goes down.

No single tool covers all scenarios. Many locksmiths recommend owning both Xhorse and KeyDIY devices to maximize vehicle coverage, as each supports remotes the other may not.

What BMW G Key for Autel ACDP APPRO2 Xhorse?

What’s the difference between BMW G series key and F series key？ Can we use F series key for G series?

Here is the clue.

 

 

 

Technology and Features:

• F Series Keys: Operate with older security systems like CAS (Car Access System) or early FEM/BDC (Front Electronic Module/Body Domain Controller). They support basic functions like locking/unlocking, trunk release, and Comfort Access (proximity-based unlocking/starting). Frequencies are typically 315 MHz (North America), 433 MHz (Europe/Asia), or 868 MHz.
• G Series Keys: Use advanced FEM/BDC systems or newer BDC2 modules, with enhanced encryption for security. They support additional features like remote start, remote parking, or vehicle status display (on Display Keys). Some G Series keys use Ultra-Wideband (UWB) technology for BMW Digital Key compatibility, allowing smartphones to act as keys.

Frequency and Internal Components:

Both key types use specific radio frequencies (315 MHz, 433 MHz, or 868 MHz), butG Series keys may incorporate newer chipsets (new NXP chip)for improved security and functionality. The internal boards, such as PCF7945 for some F Series keys, differ from those in G Series keys, which are designed for newer vehicle architectures.

 

Can an F Series Key Be Used for a G Series Vehicle?

Short Answer:No, an F Series key cannot be directly used for a G Series.

 

Some devices support adding a spare key to BMW BDC2 immo system at present, including Autel IM608, AVDI, Yanhua ACDP, Xhorse, Appro2, CGDI A2, Keydiy KD-X4, Launch X431 IMMO tablet etc.

Tips to Program Nissan Kicks 2025 Key with Autel IM608

Here is the user's working experience on Nissan Kicks 2025 smart key programming usingAutel IM608.

2025 Nissan Kicks smart key WITHOUT Consult4!

First try: IM608+40 PIN Cable+APB131 adapter.

When I first came to the vehicle I extracted the pin code within the HFM via eeprom, but I didn’t realize that there is no OBD communication even with the Nissan 40 bypass cable and so was not able to program the extra remote.

This time I came more prepared, I had wiring diagrams of the body control module to pinpoint where the CAN pins are. I realized this vehicle has both Can and CanFD pins and probed both pairs separately.

When hope began to run dry success struck!

The combination that worked was probing the low speed canH and canL while also having theAutel CANFD adapterconnected AND going through 2024+ Pathfinder.

So, extract PIN via eeprom, and then connect the Autel's CANFD adapter's CAN H+L pins directly to the vehicles CAN H+L lines, instead of thru the OBD (used a chrysler bypass cable for the CAN probes, bypassing firewalls), and attempt process selecting Pathfinder 24.

It has also been verified that consult3+ does NOT connect to the vehicle or pull the vin number.

Hope this helps somebody.

Disassemble the original MLB key.

Run KD-X4 software App.
Go to Programming function- KD-MP function.

Check wiring diagram.

Select the one that matches the MLB key.
Here the key board is the same as type 5 wiring.

Need to remove 2 capacitors and solder two wires (VCC and GND).

Solder the adapter with original key.

Connect the solder adapter withKD-MP, connect the KD-MP tool to computer via type C usb cable, connect 12v power supply to the KD-MP.


Put the original board to the induction coil of KD-MP.

Run KD-MP App.

Autel IM608 Range Rover 2019 Car Starts Keyless Not Working Solution

Problem 1:

It’s a Range Rover Sport 2019. Trying to add a spare smart key withAutel IM508andAutel’s universal Land Rover key. Cloned key successfully, remote works and car starts only when put key near sensing area. Proximity does not work. How to make the proximity to work?

 

Problem 2:

After a generate 2019 Range Rover key withLonsdor K518 ProandJLR smart key, write the key lock unlock works.
But you have to be close to the steering to start which is keyless entry won’t work.
And this car has no issues all good he just lost the key.

 

Solution:

These models’ UWB ((Ultra Wide Band)) function is enabled. All current Land Rover models employ ‘Ultra Wideband’ (UWB) technology within the vehicle’s Smart Keys. This is normal if keylessgo is not working.

Almost all tools use the same solution for these vehicles, reading key(s) from the RFA and emulating them into change-ID or their own keys. This is fine for places outside of the EU/AU that use non-UWB keys.

UWB equipped vehicles require one of several solutions, one is to use the emulated keys & alter the CCF to turn UWB off. UWB is a setting so it’s a frequency setting on those newer vehicles you have to turn it off when you’re not using a OEM key cuz the key is not capable of ultra wide band.

You can turn off ultra wide band after you make a new key if you use a clone style key to get the remote wireless functionality back.

Lonsdor also has a function to disable UWB.

Go to Lonsdor Modify vehicle config function.
Disable UWB function.
Then check if the key is working properly.

 

 

However this has the side effect of disabling telematics and navigation as they are linked to the UWB function in GWM & BCM. This also removes part of the security solution for these vehicles.

Another is to use a UWB emulator like Abrites do, this won’t fly with owners of these vehicles until they’re much older than they are now, soldering a tiny, cheap PCB into an expensive car is not a good look. Once again however this removes a part of the security solution.

 

The real option for JPLA/K8D2/M9R3 etc is to remove the RFA and replace it with a new unit and then code new keys to it and link the RFA to the car.Full keyless only with new RFA or new MCU.

If the car can be unlocked by holding the door handle =PSPS=Passive Entry Passive Start =keyless entry function. You have to replace the RFA unit or MCU chip.

Always check vehicle and KVM information and verify if KVM (RFA) is locked or not.
You can check KVM information using Lonsdor K518 Pro series devices.
Go to Immo& Remote->Jaguar-> Select from vehicle-> Jaguar (2018-)->Smart Key->Read vehicle info.
If it is a Land rover, go to Immo& Remote->Land rover-> Select from vehicle-> Land rover(2018-)->Smart Key->Read vehicle info.

 

 

If the RFA is locked, you cannot clone key to add a spare key.
