95 mustang key fob help

I have a 95 ford mustang GT. I just bought a new key fob and am not able to program it. I would really like to get this thing working. I do have a viper security system that was previously installed before I bought the car and I have a Valei switch by my knees. Thanks for your help.

Sincerely.
