Detailed Answer
One-key pairing: press the transmitter pairing key and receiver pairing key together (or a short press), completing pairing in 1-3 seconds. Compared to DIP switches (requiring opening the housing), one-key pairing is fast and safe (no tools needed on site). The LIDEER LD series uses one-key pairing; replacing a transmitter/receiver is done in 1 minute. XINGJIA supports both learning code and DIP switch. After pairing, the old unit automatically becomes invalid.
| Method | Both keys pressed |
| Time | 1-3 seconds |

Note:Test immediately after pairing and confirm the old remote is invalid.
