Can somebody here help me to start up my Gen 3 Viper that is located in my garage.
Since today the Viper will not start anymore.

The immobilizer stays on when turning the key. The same occurs with the spare key.
The alarm function works and also the boot release with both keyfobs.

Tomorrow I will buy 2 new battery's CR 2016 per keyfob.
Probably I have to do a reset so that the key recognises the Viper and vice versa ? How is the reset procedure ?

Thanks for your help !

Rob.
