Hyundai Matrix 1.6A , the alarm system is of factory.
My remote got wet , probably the mainboard is damaged and I do not have a spare remote.

I couldn't find the override button for the alarm after unlocking the car using the key. I hope someone could help me locate the override button here , it's urgent.

thanks.

 

We don't have the Matrix here in the US but this procedure works for US Hyundai vehicles:

To turn the alarm off try the following:
1. Unlock the door with the key, which will cause the alarm to start honking.
2. Insert the key in the ignition and turn it to the "ON" position but do not turn to "START".
3. Wait for 30 seconds.
After completing the steps above, the system will be disarmed.
