Dodge Repair Questions? Ask a Mechanic for Answers ASAP
I will guess that you have a grey colored key. If so then there is a possible problem with the key or the module for the vehicle theft system. The module needs a valid signal from the key to start. If it does not get one then it will start and stall 3 times then completely lock you out until you can get the problem fixed. Unfortunately there isn't a great deal you can do to fix the problem. The system needs the proper scan tool to diagnosis the concern and unless you have one....
If this doesn't have the grey key then it still has the same function but it uses a door switch to disarm the security system. Same situation though, you need to know what triggered the system and will need a scan tool to find out what did it. Sorry the news isn't good but some systems just are not very cooperative when it comes to self repair.
