Hi there - your RAM pickup should not have a security-enabled key, just a standard non-security key. Your symptoms suggest that perhaps the ignition switch or "starter-limiting" relay (transmission interlock switch - Park or Neutral), may be preventing you from cranking your engine. I would recommend an engine starter system inspection by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
