How keyGo works
Once you have keyGo on your Key Smartcard, all your entry and exit taps across the network will be analysed to calculate the best day fare for your journeys based upon the tickets you could have purchased that day. keyGo will then charge the most appropriate ticket(s) for the journeys you made that day against your nominated payment card.
If you hold a Season ticket on your Key Smartcard, keyGo will only charge you for the journeys you make beyond Season ticket's validity.

What fares are charged?
The best day fare offer is based on tickets that can be bought on the day of travel. We will charge you the cheapest fare based upon the taps you have made on your journey and the journey length to best guess the route you took. Fares are based on paper equivalent tickets defined as Peak, Off-Peak Day and Super Off-Peak Day single and Day return routed 'Any Permitted', 'Southern only', 'Thameslink only' and Oyster fares for journeys made wholly within the London zones 1-6.
Where journeys occur within the London zones 1-6, journeys will be Price Matched with the equivalent Oyster fare or Travelcard price for journeys that begin or end outside the London area. This includes daily capped fares.
Journeys made on Gatwick Express and services between Merstham and Gatwick Airport will be charged the National Rail fare.
Please note that first class fares and Railcard discounts are not available on keyGo.
