Autostart 2 Way Remote Stopped Working After Car’s Battery Died

My car is Honda accord 2016 LX Sedan 4-cyl 4D - regular start by a car key. My Autostart 2-Way LCD Remote Start System AS-2482TWS is working fine. However, my car's battery sensor died. After that was fixed, my Autostart 2-Way LCD Remote stopped working. e.g. pressing the 2-way 5-button SST LCD transmitter do not unlock my car's door, etc. How to fix this?

I would try reprogramming the remotes.

Please see the photos of my LCD Remote and hood: https://photos.app.goo.gl/QENSmQjiBNNduD9P6 I am not sure which are the hood pin and programming button?

Use the programming button on the antenna.

I do not understand. Would you mind elaborating, please?

See the instructions above. They say to press and release then hold down the button on the antenna. There's a picture of a hood pin, but no mention of it in the remote programming steps.

Where is the button on the antenna? Is my equipment different? Please see my photos above.

I looked again at your pictures. I don't see an antenna. It looks like 3 pictures of the remote and an under hood picture. Try tracing the wiring to the antenna.

Which wiring to start tracing?

Let's start from the beginning. Look on the inside of your windshield near the top. Do you see the antenna pictured above? If not, you need to find the remote start module. Once you locate it, look for a black flat, multi wire cable. Follow that wire to the antenna pictured above.
