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

Thanks for your help! Would you mind helping further, please? I located the antenna (see photo at https://photos.app.goo.gl/QENSmQjiBNNduD9P6 ). The antenna LED is blue. 1. I turn the key to IGN ON but do not start the vehicle. 2. I press, release then press and hold the antenna programming button many times, but the antenna LED do not start flashing rapidly. 3. I press, and hold f or Side button but the remote do not generate a long beep.

You're not being clear. Are you saying the blue LED is staying on constantly? Is is flashing? I'm wondering if you're in valet mode. https://www.youtube.com/watch?v=hgHBfsPd728

The LED is usually off (no light). When I press, release then press and hold the antenna programming button, the blue LED is staying on constantly. It does not start flashing. 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.

The Honda OEM 1-way remote (transmitter) works ! Only the 2-Way LCD Remote does not work. My control module is Autostart PS-4481TWS. My 2-Way LCD remote is Autostart ASRS-7505.
