I have around 1500 miles with DSC unit and absolutely love it.
Granted my FL5 is a daily driver + occasional spirited drive through some curvy roads.
Stock suspension depends on the mood I drive in all 3 mods without any issues.
As others mentioned just leave the key inside or put them out of range of transmitter. I usually leave the key in garage on the table, while I’m washing my car…
Honestly, it looks like you did all you could to protect it. With time it's gonna turn into rust bucket one way or another.
I daily my car in Ohio, where we getting tons of salt on the road also... When the weather allows, I just wash my car and use undercarriage adapter to wash it and get salt...
When I got mine, I told dealer that want to swap wheels on the car before I'll drive it away.
Granted its my daily so I'd need to switch them one way or another.
They ordered the wheels and installed them. Honda was actually running promotion buy 3 get 1 free so it ended up being cheaper then...
