Mabcbook Pro 2015 keyboard and trackpad unresponsive

[Pimmp]

Hello. I recently replace the battery of my MBP 2015 did a reset of SMC and NVRAM. After boot the keyboard and trackpad is unresponsive. Continuing to replace the ribbon cable but the error still remains.
Any advice will be much appreciated.

Did the keyboard become unresponsive after doing a SMC and NVRAM reset?

Does the keyboard light up?

Works with an external keyboard and mouse?

So yes. Unresponive after resetting.
Keyboard does not lit up.
Computer works with mouse(bluetooth) and keyboard (connected via thunderbolt display)
