Amusingly, you can and probably SHOULD lock a doorless wrangler. On a JL and even on the JK, the alarm system still locks out some functionality. And most people don't take the tailgate off, which when locked, kinda keeps people from getting at the little compartment under the cargo floor. It's not really an effective safe place, but just a neat thing. You can also put a lock on the hood, which is a good idea since that way nobody can disable the security system lol. Edit: Also of note, the JL wrangler uses an RFID chip for the ignition startup itself. It's separate from the rest of the keyless go system.
