Mine is a similar problem to others posts. Flat battery recharged/reconnected sets off alarm but neither of my remotes will deactivate. Replaced batteries and tried all previously mentioned remote key button pressing to no avail. Same response having spoken to Scorpion about removing unit from under dash and sending for reprograming. Only way to start car is to insert key in ignition, turn to position 2 and disconnect/reconnect battery negative terminal immediately alarm pauses. However, alarm sounds immediately on switching off ignition. No details of scorpion model, no user manual either so if Pascal moderator can help it would be greatly appreciated.
