Tutorial on Yamaha p125 clunky keys repair. Step by step. Home repair guide.
The Yamaha P-125 is a portable digital piano introduced in 2018.[1] It replaces its predecessor, the P-115.

The P-125 has 24 different voices which range from Grand Piano to Rock Organ, and comes pre-loaded with 71 preset songs. There is a built in metronome as well as a built in recorder which can store roughly 100 KB (11,000 notes) for play back or upload to an external device via USB. Keys are Yamaha's Graded hammer standard (GHS) which range in weight from the low keys to high keys to more accurately mimic the feel of an acoustic piano.[2] The overall weight of the keyboard is 11.8kg (26 pounds).[3] The keyboard can come in colors black or white.

Yamaha P-125 is very similar to P-115[4]: both of these pianos have the same weight, size, polyphony, keyboard action. P-125 has improved 2-way speaker system, a few more voices and slightly modernized design.
