The key can likely still be purchased, but based on the part number for the AE101 Corolla SE-G key, you'd be looking at approximately $400 NZD + shipping from Japan. The OP said he has an alarm anyway, so a replacement remote would be pointless. Install a rare optional Air Purifier instead

Also very common in Hilux Surf's.

They appear to be fitted into the vehicles after assembly,
either before or at the time of sale.
