Check KeyGo is right for you
- Once you set up KeyGo you must touch in and out for every journey you make - even if you have a season ticket so we know how much to charge you
- If you do not touch in or out, this will generate an incomplete journey which we will notify you of by email. If you don't then complete your journey, we will charge a £25 incomplete journey charge
- You should sign up using your primary email address or at least one that you check regularly, it is important that we are able to contact you in relation to your account
- KeyGo cannot be used on TfL or other train company’s services with one small exception. Find out more about this in the Using KeyGo section
- First Class and Railcard discounts do not currently apply to KeyGo
- You must keep your payment card details up to date
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 the Season ticket's validity.

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.
Where journeys occur within the London zones, 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.
Journeys made on Gatwick Express and services between Merstham and Gatwick Airport will be charged the National Rail fare.
