HP Prime 2 key not working.

[Thai Rat]

My occasionally used 3 month old calculator 2 key no longer responds.

To enter a 2, must copy one, or use an expression.

My calculator is about 3 months old, purchased from Amazon, Amazon return policy 30 days.

The key doesnt respond when using in combination with SHift or Alpha.

Looks like garbage, repair probably cost prohibitive.

Any suggestions appreciated.
