It did change my life when I got my first cordless fridge grinder!Well it's still a deadlock, but as it has the options for handle connections and isn't generally as well shielded it's not as defended but it will work fine to prevent most smash and grabs.
The advantage of aftermarket units is that the bad guys have an incentive to research how to defeat the factory options as they are in every van, but there are lots of aftermarket units so that's less likely. Unfortunately this might not prevent the oiks having a good at the door skins anyway with a battery cutting tool to see if they can get in.
Unfortunately it changed the bad guys lives too
