Chrysler Repair Questions? Ask a Mechanic for Answers ASAP
Do you see a red light in the dash? Do you have another key to try?
Since you don't have another key to rule out a bad key then the next step would be to call a mobile locksmith to have him cut and program you a new key and see if it starts, but if it doesn't there is a good chance you will need a new SKIM(Sentry Key Immobilizer Module) which will need to be programmed with a scantool.
There is no way to bypass this to get it to start because that would not be safe and easy for someone to steal your car. The proper way would be to connect a scantool to retrieve the codes from the SKIM module to determine the issue..
