Don't know how the new Ts work but on old ones such as my 2006 with keyless doors and keyless pushbutton start/stop:

1. Put full key under driver mat
2. Lock door with plastic key; go surf, kayak or sail. Make sure alarm is on.
3. Use same to unlock car.

Cheers,

vwW12: Will the unit still try repeatedly to unlock / lock with the fob under the mat? Does the plastic valet key 'out rank' the fob remaining in the car?

On a 2006, one locks with the plastic key, goes surfing, comes back, unlocks, and goes.

Car will not attempt to unlock on its own.

Car can be opened and started and driven with plastic key in case of absence of the full remote key.
