For those who have the vulnerable kias-- a club is only going to work a LITTLE BIT. That is, it will provide a visual deterrent for the thieves who MAY just move on to another vehicle. Sadly, even the best steering wheel clubs are still super easy to defeat. Probably good to get as they're cheap (and many community police departments are giving them away for free). But it wwon't be a guarantee.
If you see the amazon reviews from the one posted above, it bends like butter. Several people have had their car stolen in the reviews. Also, having to put/remove it each time is an annoyance, I drive my car 4 times a day, so even though it could be useful as a visual deterrent (not much as most creeps know you can break them in seconds), it's not for me.
I'm going the immobilizer way. I have the factory alarm, but it's useless as a lot of times they break the drivers door lock and turn it, causing the alarm to disarm as the car thinks you're using a legitimate key to enter. So first of all, I'm going to disable the key lock switch. If I ever have to use the key in the lock for any reason the alarm will go off and the car won't be able to start for a minute, but honestly I've used the key to enter the vehicle probably twice in 9 years.
Second, i'm going to install an immobilizer that disables the starter motor. Yes, they could pop the hood and bridge the starter solenoid, but realistically that's not going to happen as they will probably just leave after the alarm goes off, nor they are gonna spend time trying to understand what's going on with the car or why it doesn't start.
The main objective is avoiding them to start the vehicle and leave. Avoiding an intrusion is impossible, as they can pop the door lock and turn it or just break a window, and any other thing like a steering wheel club can be defeated in seconds.
