As per title above. Help needed.

Inside battery replaced with new one, also same not working.

Red flashing light below aircond/radio is blinking like normal.

What should I do next?

Just take to remote control key guy. They know how to reprogram. They will turn the key about 10 times to enter some sort of program mode then with their detector will be able to program the new remote. Subang area is Rm50

You mean setting off the car alarm by unlocking car door with the physical key first, then proceed to try this method?

Ok, this is one option.

No. Turn ur key in the ignition to acc-on(or on-acc position, i cant remember) position 5 times as fast as u can (until u hear the car beep)

Then press the unlock button on all ur keyfobs. This will re register ur keyfobs to ur car alarm system.

After that (i cant remember this step,) u need to turn ur engine on (or maybe take out ur key from the ignition, i cant remember). U need to experiment in order to find the correct sequence

Yeah, but I'm outside of the car (with the locked doors) now as I couldn't gain access into the car due to faulty remote control...

Will give your method a try anyway...

Just wondering how long was your car idle? could it be car battery depleted?

iinm Toyota red blinking light is Cobra alarm (but im not sure Avanza got or not) so if your car battery depleted u have to open the door with key and put the key fob at specific place (my car is left side of the steering) then only u can start the car.

The engine was shut down for less than 2 hours after a 40 minutes drive. Alternator was replaced new some 1.5 years ago and the red blinking light near radio console points to battery power remains available.

Avanza key switch is on right hand side of steering column, facing the driver door.

Then try to unlock ur car using key, and do the on-acc until ur car beep, and try to turn ur car on. Idk if it works that way.

Yes, will give this method a try maybe expecting an alarm setoff.

Thank you all guys for your contributions.

Manage to get the remote control back to working order on first try.

After new battery (CR2032 size) replacement from KK Supermart, I clean the button contacts on the internal chips as per youtube below, problem resolved.
