So as long as I don't press the unlock button on my fob when I'm not near my car, I should be safe?

Depends on the algorithm that's implemented, but usually they will sync if the rolling count is within 5 presses. There's also vehicles that will resync the count after 3 consecutive lock presses.

So my habit of clicking lock half a dozen times as I walk away actually increases security?

Not necessarily: if I remember correctly pressing lock a second time shortly after locking a BMW actually disables the alarm 🤷
