Locked out :-(

2017 Mk3 Saloon 1.2 110 SE-L.

Came out to vehicle earlier today - neither key working (no red LED when unlock pressed), and zero response from vehicle.

Confident 12v battery is decently charged (successfully used day prior...)

Changed key coin batteries (BUT - both keys flat at same time?)

Went for manual key entry, so removed drivers door handle cover.

The key inserts, BUT barrel rotates freely 360 degrees - no unlocking!

Therefore - UNABLE to enter vehicle, and needed to bus to work.

Any ideas, please? :-(
