You can turn off the keyless entry feature if you wish, which should defeat the signal boosting theft devices. Means you have to use the keyfob buttons to lock and unlock, but still more convenient than wrestling a heavy monstrocity on and off the steering wheel.
Yes, you can disable it but the point is, it’s there for convenience why would you want to disable it?
