I sold a roof rack on Kijiji and guy purchasing was a BWM mechanic, the rack for for his Wife's car a 2018 LE.
I asking him if he took any special measures to deter thieves , he said NO ad the LE models have no smart key , just an old fashion Key so these were not getting stolen as XLE and higher trims.
But he did say he heard a recommendation that is was a good idea to remove a key ID that is apparently found on the key barrel on the driver side door ?
This does not really make sense to me ? It would stop the thief's from being able to order replacement keys ? but not stop them from breaking in and driving off.
