The Kia Boys trend was a perfect example of the consequences of USDM and CDM model differences
I was confused when I heard about the trend of people stealing Kia and Hyundai cars with a USB cable because I thought the whole point of an immobilizer was to prevent a simple exploit like this. I then read that most Kia and Hyundai models without keyless start didn't come with immobilizers from the factory in the US. In Canada, even the cheapest Pontiac G3 wave had to come with an immobilizer since 2007.
I kind of wrote this off as a simple choice like not going the extra mile to install DRLs in USDM vehicles because it isn't required like in Canada until I was checking my friend's 2013 Kia Optima for the type of TPMS system it had.
Turns out this Kia has an immobilizer because of Canadian regulations, but does not have a TPMS system because there is no requirement for Canadian cars to have it. It makes sense because of so many people swapping tires and rims and not bothering to pay for TPMS sensors but for two countries where car safety standards and model availability is practically mirrored, thought it was neat that there are still huge differences in standard regulated equipment.
TLDR 2013 Kia in Canada has an immobilizer but no TPMS. USDM models have TPMS but no immobilizer.
