Does anyone know if this works on push-start Znen ZN 125 21s?

I can’t believe I found this. Been stuck with my Znen ZN 125 21 too.

My Znen ZN 125 21's immobilizer is stuck. Hoping this helps.

Waiting to see if this will work on my Znen ZN 125 21 as well.

Was about to tow my Znen ZN 125 21. Let me try this first.
