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, including any Railcard discounts. KeyGo will then charge the most appropriate ticket(s) for the journeys you made against your nominated payment card.

If you hold a Season ticket or other ticket on your Key Smartcard, KeyGo will only charge you for the journeys you make beyond the Season ticket's validity.

Check the KeyGo Network map to see where you can go!

How to set up KeyGo

  • Once you have a Key Smartcard, you can add keyGo through your online account
  • Your keyGo account will be associated with a credit or debit card for automatic payment to be taken via a Continuous Payment Authority
  • Two hours after signing up to keyGo, you can start your first journey by touching the card reader at your chosen station. Or use our mobile app to load keyGo to your Key Smartcard within 15 minutes
  • Add your Railcard to your online acccount and we will discount your keyGo journeys
  • You can top up your keyGo balance with extra credit at local retailers with Payzone

How much will I be charged using KeyGo?

The best day fare offer is based on tickets that can be bought on the day of travel. KeyGo 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.

If you have a Railcard added to your online account, we will take this into consideration, and discount your journeys when the Railcard is applicable.

Where journeys occur within the London Zones 1-6, journeys will be Price Matched with the equivalent Oyster fare, Travelcard price for journeys, or National Rail fare, whichever is cheapest. This includes daily capped fares.

If you do not touch ini or out, and do not complete through your online account, we will charge a £25 incomplete journey charge.
