LAUNCH X431 is developing a new IMMO programmer: the X431 G5. Judging from its features and name, the G5 is likely a new addition to the XPROG3 (G3). This article will briefly introduce the features of the X431 G5.
NOTE: The LAUNCH X431 G5 is not yet available for purchase; there may be some adjustments upon its official release.

Which X431 diagnostic tools does the LAUNCH X431 G5 support?
The X431 G5 can be used with the X431 PAD series (X431 PAD V ELITE, PAD VII ELITE, PAD IX), as well as comprehensive diagnostic tools such as PRO3 V+ ELITE/ PRO3S+ ELITE.
Q: How do I use the PC software for the LAUNCH X431 G5? Can I use the XPROG3 (G3) PC Adapter with the G5 to connect to my computer?
A: The LAUNCH X431 G5 can connect directly to the computer; a PC Adapter is no longer needed.
Can the LAUNCH X431 G5 completely replace the X431 Key Programmer for key generation?
A: Yes, the LAUNCH X431 G5 supports key generation and can be used in conjunction with the X431 IMMO tool.
