The key to the code would depend on the make and model of the headphones. Likely to the '0000' or '1111' or similar.
The most common PIN is four zeroes in a row, 0000. Two others you may encounter on some devices are 1111 and 1234. Try entering those when you're prompted for a PIN, starting with 0000, and most of the time, the pairing finishes successfully. If issue persist, proceed with these steps.

The phone was released in 2018, so it can't be under a purchase deal, so it is either reported stolen, or someone has exceeded the number of tries to open it.
