Is there a way to fix this without completely disabling the

yes but you'll need 3oz human semen, a sword and a ruby-tipped sceptre (i've only done this oncㄷ 듀랙ㄷ)

If the car detects it is surrounded, it explodes, killing everyone within 45 ft.

the person inside turns their car off, walks outside and dismantles the trap, then gets back inside.

IF the car is unmanned, then clearly the purpose is theft, and so it's just as much stealing as it would be if the car was parked.
