How effective is dodge’s key programming lockdown and other questions

Just got my charger and I am sort of new to owning dodge. Obviously I am aware of all of the cons that comes with owning one of these and I have done plenty of research before getting the car so I know off all the ways thieves go about stealing these cars. I got the car however because this was my dream car for the longest time and if it so happens that something bad happens oh well, I am not living in fear but I will do my part to protect my car. I am planning to ask my local dealership to lockdown the rf module, I would like to know how effective the RF key lockdown is. Does that prevent any key from being programmed as advertised? Or has there been times were thieves are still able to program new keys if anyone is aware.
