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.
Please see the photos of my LCD Remote, antenna and under hood:

There is no hood pin.

I had tried:
1. I turn the key to IGN ON but do not start the vehicle.
2. The antenna LED is usually off (no light).
When I press, release then press and hold the antenna programming button, the antenna LED is blue and staying on constantly. It does not start flashing rapidly.
3. I press, and hold f or Side button but the remote do not generate a long beep.
4. My remote cannot lock and unlock the car doors so it is not in valet mode.
Anyway I press the lock and the lightning bolt at the same time but that do not fix the problem.

How to fix this?
 
My guess is the unit in the car is not receiving power. Was it connected directly to the battery, and is there a fuse in that circuit?
Are you talking about the antenna?
I look under the hood and driver seat but am not sure.
How to find out?
