Recently some users reported that they had the error “Device no response” when updating Launch X431 key programming software/firmware.
Example 1:
Failed to clone transponder with Launch X431 PAD VII and X-prog3, data communication failed. PAD 7 asks to update key programming software/firmware, but fails to update, throwing an error device no response.
Example 2:
Launch x431 immo plus won’t update new key programming software, WiFi is good, error device no response.
Solution:
To activate the Key Programmer function (transponder/remote clone and generation related functions), you should have the Launch X431 key programmer add-on module.
You cannot update key programming software without that key maker.
This is the Launch x431 key programmer.
The key programmer is compatible with IMMO Plus, IMMO Elite, PAD V and PAD VII and more to come.
Connect key programmer with X431 tablet like this:
Connecting x431 key programmer will allow you to use these functions
