Answers to frequently asked questions on using keyGo when you travel in and out of London with Southern.

Travelling with keyGo

Yes you can. At the end of the day, we analyse all your entry and exit taps and apply the most appropriate fare for the journeys you made. For example, if you travelled from Brighton to Haywards Heath, then later in the day travelled to Gatwick Airport, you would be charged a Brighton to Gatwick Airport ticket.

If your journey with us is delayed by 15 minutes or more you can claim compensation under our Delay Repay scheme. With the Key Smartcard you can benefit from Auto Delay Repay. We can in many cases, tell when you may have been delayed and let you know when you're owed compensation. Just select Automatic Delay Repay in your online account preferences.

No. We would recommend that you buy a valid paper ticket for the whole journey. Otherwise you would need to get off a train and touch out at the end of the Key area, and then back in at the same station in order to continue your journey outside of The Key Smartcard enabled area.
No. As above, you would need to touch out at the end of the keyGo area, and then re-enter the station using Oyster or contactless in order to continue your journey with another rail operator within the London zones.
keyGo can only be used on Metrobus and Brighton & Hove buses. Please see the keyGo map for the areas covered. Please allow two minutes between your exit tap at a train station and entry tap on the bus to ensure that your Key Smartcard is read correctly on the card reader.

If you already hold a Smart Season or Smart Day ticket and you travel further within the keyGo area, you will only be charged for the additional part of your journey by keyGo. You must ensure you tap at both ends of your journey otherwise you may be charged an Incomplete Journey Charge.

Please check the map for where you are able to travel with keyGo.

Yes, for all train journeys you should touch in and out, even if you hold other tickets on your Smartcard. If you don't, you may be liable to pay the Incomplete Journey Charge of £25 or a Penalty Fare. We reserve the right to cancel your keyGo account for repeated misuse. When travelling on the bus, you only need to touch in.

If you have not touched in or out, we will email you to inform you of the missing tap. You can then log into your account to amend the incomplete journeys. You will have up to the Wednesday following the date of travel to add the missing tap, otherwise a £25 Incomplete Journey Charge will be applied to your account. You can complete 3 journeys online in a 28 day period. After this you should contact Customer Services.

Where possible, we try to auto-fill your journeys based upon your regular journey patterns. If our system has auto-filled the wrong station, you can amend this through your online account.

If you have a smart phone, you can load KeyGo to your Key Smartcard using our mobile app.

Once loaded, jJust touch your Key Smartcard on the card reader at a station and touch out at any of stations in the KeyGo area.

If you don’t want to use our mobile app, you'll need to allow 2 hours from registration before you can make your first journey. As part of the registration process, you will have chosen a station to start your first journey. After your first journey, you can start travelling from any of the stations where KeyGo is accepted as shown on the map.

You are not able to start your first journey on a bus.

KeyGo is valid on all Gatwick Express, Great Northern, Southern and Thameslink services within the KeyGo area.

KeyGo can also be used on Great Western Railway services between Redhill and Dorking Deepdene and between Warblington and Brighton.

It is not possible to start or end your KeyGo journey from Dorking Deepdene as there are no card readers at this station.

KeyGo is only valid for travel on Gatwick Express, Great Northern, Thameslink and Southern services in the keyGo area. You are also allowed to use Great Western services between Redhill - Dorking Deepdene and Warblington - Brighton.

If you travel on another train service, Transport for London services (eg. tube), or beyond the keyGo area, and do not have hold a valid Smart ticket (ie. Season Ticket) on your Key Smartcard, you may incur an Incomplete Journey Charge or a Penalty Fare.

We recommend that you do not sign up to keyGo if you regularly travel to St Pancras with East Midlands Trains. This is because we are unable to receive tap data from East Midlands Trains’ gateline at St Pancras and the system will therefore always treat your journey as Incomplete. To avoid an Incomplete Journey Charge, we recommend you do not add keyGo to your Key Smartcard in this instance.

Log in to your keyGo account online and update with your new card details as soon as you have them. If your card expires and you use keyGo, your keyGo account will be closed and prevent you from further travel.
Your journeys will be calculated and updated daily at 4.30am. Please ensure your bank account has sufficient funds to cover any automatic billing required before travelling.
If we're unable to take payment from the card details you provided, you'll receive an automated email from us to let you know that the payment has failed. Please ensure you have sufficient funds in your account and your card details are kept up to date. If not, we may close your keyGo account.
To use KeyGo, you are agreeing to allow us to take automatic payment for the journeys you make, known as a continuous payment authority, against your registered debit or credit card. This means that you agree for us to pre-authorise your card and then deduct the cost of your travel on an on-going basis (the day after travel).
Pre-authorising a credit or debit card puts a temporary hold on a sum of money in the customer's account (in this case £0.01 - one penny) and typically lasts 3-5 working days. No money is actually debited when a card pre-authorisation takes place, it is simply used to check that the card is active.
