If they have the key bit and the transponder that fits to the car, they don't need the radio module to open the car and get away with it.
If they have a radio module that fits the car they can get in the car. If they are in the car and have enough time they can get away with it.
The only solution is to replace the whole locking system.
An alternative could be to install a tracking system and some kind of addidtional immobilizer, so you get an alarm on you smartphone when somebody is trying to manipulate or move the car.
But all this can't prevent that they try to get in the car and cause damage. So best is to also secure the house and the garage. But what if they follow you when you leave with the car. In the end it is complicated to prevent everything.
