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

Taipan. the short guy with the car  infront of AmBank and Baskin Robbins . He is usually there in the afternoon onwards.

Reset us alarm. I cant remember whats the seq. Iinm it is Turn ur key to on-acc position 5 times rapidly until ur car beep. Immediately press unlock button on all ur keyfob, then take out ur key.

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

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.

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.
