Since most users search for "zh jt-03 remote control code" because they want to pair a new remote to an old receiver (or vice versa), here is the for 90% of ZH JT-03 systems.
Most JT-03 remotes use a (or pin‑compatible HS2260, EV1527 – though EV1527 is often learning type).
If your JT-03 has inside (no microcontroller):
