your remote control lost memory already, need to reset it again. I face this problem also after half year used my vios 07.
Get your 2nd key and user manual for vios alarm, it got step by step how to add on again your remote to your car alarm.
One more thing, if the remote control lost memory already is no way to deactivated the alarm coz if wan deactivated the alarm need separated u key and remote control, insert the key and turn on it, then put your remote at the yellow sticker at the right of your dashboard (only open the door then u can see it), so if the remote control lost memory, no way to deactivated it.
the toyota SC technician tell me that don't press the remote continuosly too fast if cannot lock o unlock, it will cause the signal crash then made the remote control lost memory... dun know true or not...
