According to this FCC test report for the LXZK-TX1021 remote control, this remote uses HF at 433.92MHz92 MHz.
In other words: it is not an IR remote; it uses radio, so it does not send any IR you can receive.
It did pass the test, though.
Apart from that, you should put a >20kΩ>20 kΩ pull-up resistor in between 5V5 V and Out, and a small cap in parallel with the 100μF100 μF, both as described in the datasheet, if you want to wire the receiver up correctly.
