Looking for TRS-4 Additional Remote Transmitter for SRi300 or OEM500i Alarm from Scorpio , my remote is functional but for some reason drains batteries within days , sometimes hours. The item is relatively inexpensive , but seems to be discontinued , and no longer in stock on all websites that I've hunted . What I've been doing to save the battery is only putting the battery in to arm/disarm then pulling the battery out . This seems to work but is annoying, and poses as an inconvenience . Nothing on eBay etc. Any one willing to part with their old remote/ extra remote ? PM me we'll work something out, there has to be one here .
