How do you find out what model viper car alarm you have?

To find out which Viper car alarm model you have, check for the model number on the main control module, usually located under the dashboard or near the steering column. You can also look for the model information on the remote control, if you have it, as it often displays the model number. Additionally, you can refer to the installation manual if you still have it, or contact Viper customer support with your vehicle details for assistance.
