Good Morning and welcome to JustAnswer!!!
Here is a case that will help you..
Vehicle IssueBattery discharged, Unable to deactivate alarm or program key fob => Disarm Viper VTSS as follows:;In what area is the electrical problem? >> Vehicle theft security system What is problem with the VTSS(theft alarm)? >> Unable to disarm >> Unable to disarm with RKE Fob
System or ComponentWill Not Unlock / Disengage;Customer Concern (No DTCs);Vehicle Theft Security System (VTSS)
RecommendationDisarm Viper VTSS as follows: The viper coupe is the new style viper which came out in 1996, it has only one VTSS/RKE module (called an EEM), the only way the VTSS can be disarm if the fob is lost is to apply 12 volts to pin c11 of the EEM connector. Then the tech must resynchronize the key fobs first by pushing both buttons on the fob for 5 to 10 seconds (the horn will then beep, see the attached sheet in this packet for more information). On a viper convertible, which is the first original viper built has two separate independent modules for VTSS and RKE (this may apply to possibly all model years, but for sure up to 1995) if the key fob is lost and the VTSS is armed, the tech can disarm vehicle by grounding pin b1. Also the key fob for a convertible can be replace by a lH fob temporarily for testing. Note: The newer vipers have a disarm switch in the center console (1999 +).
Vehicle IssueThe vtss is enabled, the car will not start. The vtss will not disable because the rke is inoperative. 1994-2002 Vipers;This case pertains to a viper that the vtss will not disarm because the rke is either inoperative or the fobs were lots. This usually occurs after the car sits for a long time and the battery is dead.

RecommendationThe viper coupe (GTS) is the new style viper which came out in 1996, it has only one vtss/rke module (called an eem), the only way the vtss can be disarmed is to apply 12 volts to pin c11 of the eem BLUE connector. You will first have to program the rke, once disarmed. You may have to resynchronize the key fobs first by pushing both buttons on the fob for 5 to 10 seconds (the horn will then beep, see the attached sheet in this packet for more information). On a viper convertible (RT10), which is the first original viper built has two separate independent modules for vtss and rke, in the later years (1997 +) there was an EEM. If the key fob is lost and the vtss is armed, the tech can disarm vehicle by grounding pin b1 of the RKE modsule, or pin 18 if the vtss module, the vtss disarm wire is g73 wire (lg/or) . When applying power, you may find that there is NO WIRE in the EEM, just an empty pin, this is true on the EEM's that do not have a disarm switch. Use the manual and see section 8w-39 for the wiring diagram, also there is some good information in section 8p & 8q.
