KeyGo allows you to use your Key Smartcard for pay-as-you-go travel. When using keyGo we will only charge you for travel you take outside of any season tickets you also hold on The Key Smartcard.
If you add keyGo to your key card, you need to make sure that you tap in and out at the start and end of your trip to avoid being charged a £50 incomplete journey fee.

To get a Key Smartcard you will need to create an account with us and we will ask you for your name, address, date of birth and contact details.
If you are a parent or guardian of a child aged 5 to 15 years, you’ll need to provide the same information online as you do to register as an adult – name, address, date of birth and contact details. However, you’ll also need to provide a passport-style digital photograph of them for their smartcard. Make sure when registering for a Child Key Smartcard, you enter your child’s details for an online account.
To complete a child’s registration, you must also verify the child’s age at any Gatwick Express, Great Northern, Southern or Thameslink ticket office along with proof of identification, such as a passport or birth certificate.
A Key Smartcard can be used in two ways:
1. Use it to buy train tickets for most journeys on train services operated by:
- Gatwick Express
- Great Northern
- Southeastern
- Southern
- South Western Railway
- Thameslink
2. Register for KeyGo, which is our Pay As You Go product, find out more about KeyGo here.
If you are not travelling as frequently as before:
- keyGo is our pay as you go option, which might be a suitable alternative for you. Find out more about keyGo
- Flexi Season tickets, are another option for travel between two points on the National Rail network, with the exception of journeys wholly within London Zones 1-6 or those that include travel on London Underground services. Find out more about Flexi Season Tickets
- Contactless pay as you go is a convenient way to travel within London. There is no need to top up or queue for tickets at the station, so just tap in and out with your debit or credit card. Find out more about Contactless
In addition to smartcard options we also have Etickets. These are a great way to get tickets emailed to you, so you don’t have to queue to collect your tickets at the station. Just select ‘eticket’ as delivery option when you book a ticket. Find out more about Etickets.
Don’t forget, if you have a Railcard, you can benefit from great discounts. Buy your ticket online, and add your railcard info, to start saving. Find out more about Railcards.
Yes, so long as your season ticket still has more than a month before it expires, and the origin and destination stations of your ticket are Key Smartcard-enabled stations. You must also have purchased your ticket from one of our stations or from our website.

To touch in and out hold your Key Smartcard against a reader at a gateline or validator until you hear a beep.
If you touch at a gateline the gate will open when the card has been accepted.
If you touch at a validator the display will show the message “journey started” or “journey ended” when the card has been read correctly.
For all train journeys you should touch in and out, or you may be liable to pay a penalty fare. This is particularly important for users of keyGo and to benefit from Auto Delay Repay. For repeated misuse, we reserve the right to disable your Key Smartcard.
At all Great Northern, Thameslink, Southern and London stations, there are card readers available to touch in and out. Some stations operated by other companies do not have card readers and therefore we understand it is not always possible to touch in and out.
Smartcard readers are located either at the ticket gates or near the entrance/exit to those stations with freestanding validators. Either way, they are easy to spot with a yellow disk. When travelling in the London area, use the Oyster reader at valid locations.
All Great Northern, Thameslink, Southern and London stations have smartcard readers to collect online purchases, and touch in and out of journeys. Some stations operated by other companies do not have additional card readers to touch in and out. You will only be able to collect online purchases from the ticket machine at these stations.

Yes, the Key Smartcard can hold up to 5 products at a time. However, when buying online only one ticket can be purchased per transaction. Our system has a limit on how many tickets can be uploaded to The Key Smartcard at a card reader from a single transaction. Additional tickets can be purchased after you’ve loaded a ticket on to your smartcard. You can buy multiple tickets at a ticket machine.
Note: KeyGo is one product and one Flexi Season (up to 8 passes) is one product.
Yes you can. If your Annual Season ticket is for travel in the South East of England, you will still receive your Gold Card discounts on leisure rail travel for yourself and others, if your Season ticket is on the Key Smartcard. The only difference is you will receive a separate Gold Record Card, and your actual season ticket for travel will be held on your smartcard. If you apply by post this will be issued separately, or if you get your Key smartcard from a Ticket Office you will be given this at the same time. Use your Gold Record Card when buying discounted tickets for yourself and others.
For further information about Annual Gold Card discounts please visit National Rail Enquiries.
Tickets can be loaded on our mobile app from the App Store or Google Play, or at gates and validators at stations. If you have an issue using one of these methods, please try the other method, or speak to a member of station staff. A ticket must be loaded before you board a train.
If you board a train without loading a ticket you will be travelling without a valid ticket and may be liable for a Penalty Fare or Prosecution, as per the normal Penalty Fare rules.
If your ticket is a Flexi Season ticket you must also activate a day pass. Read more about Flexi Season tickets.
For tickets purchase online: Credit or debit cards, PayPal, Amazon Pay, eVouchers.
For tickets purchased at Ticket Offices: Cash, credit or debit cards, vouchers, travel warrants, Apple Pay and Google Pay.
