Q1: Will Lonsdor K518 Pro clone 2026 BMW X3 BCP key?
Q2: Tried to clone a 2025 BMW M5 BCP key with xhorse key tool plus, but failed. with or adapter, all failed. Any solution?
BMW BCP (Body Controller Platform 3 / U-chassis) keys use encrypted NXP transponder chips (such as the NXP NCF29X / NCF795xV and related series like 295E or 295G variants).
Cloneable vs. non-cloneable BMW U BCP keys:
Chip Compatibility: The specific PCB revision and chip markings matter.
For instance, with tools like Yanhua ACDP2, older or compatible versions (such as the 295E chip) are supported, whereas certain revised or locked chips (such as some 295G variants or post-2025/updated production configurations) may fail or lose direct cloning support depending on the firmware and lock status.
Why some BMW BCP keys cannot be cloned?
As we know BMW updated its solution after 2025 once key cloning became available on the market, so key cloning is no longer supported.
It depends on whether the key was manufactured after 2025, or the vehicle was purchased after 2025.
Disassemble key shell, check the key circuit board.
If it has the 295E chip, the key can be cloned.
If it has 295G chip, the nxp chip is locked up on the latest BCP keys and cannot be cloned.
For cloneable BCP keys, Godiag BCP adapter is helpful for reading key data.
The godiag BCP adapter supports BCP U key reading and writing through the hole positioning method, improving operation accuracy and reducing unnecessary soldering risk in supported applications.
