Remote Operation of Car Theft Alarm System This is the theft alarm system, Silent Security RP-410SU, from Cellstar Industry Co., Ltd. Although it is unused, it has been stored at home for a long time, so while there are no dents or damage to the outer box, the wrapping has some age-related deterioration, scratches, and dirt. This model appears to be the final version of the "Silent Alarm." The series is now discontinued. It seems that the remote keyless function was added from this 410 model. Please note that the operation has not been confirmed. [Brand] CELLSTAR [Model Number] RP-410SU [Other] 12V car only
