Can I buy a ticket for the Key Smartcard on the train?

It is not possible to buy tickets on the Key Smartcard on the train. Please ensure you have bought a ticket for your Key Smartcard before travelling. You can buy tickets online or at any of our ticket machines outside the London area.

Can I buy tickets for my Key Smartcard from other train operators?

Yes you can. If another train operator can sell tickets onto Smartcards at the station, you will be able to buy tickets for your Key Smartcard. If you buy your ticket from another operator, you will need to revisit them if you need to refund or change your ticket.

Is there a limit on how many tickets I can buy for the Key?

The Key Smartcard can hold up to 5 tickets at a time. However, when buying online only one ticket can be purchased per transaction (at no additional cost). 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 card at the card reader/validator. When buying from a ticket machine, you can buy multiple tickets.

Will all ticket types be available on The Key Smartcard?

We are working hard to enable more ticket types on The Key Smartcard. If the ticket you need isn’t available on The Key Smartcard, we recommend you continue to buy it on paper.

Registering the key

What details do you need when registering for a child Key Smartcard?

As 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 staffed Great Northern, Southern or Thameslink ticket office along with proof of identification, such as a passport or birth certificate.

Using the key

Does everyone need to touch in and out with the Key?

Yes, 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.

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.

What happens if my Key Smartcard stops working or my card wasn’t read properly when I touched in?

We’re here to help. For these and other queries about The Key Smartcard, please get in touch with us.

Where will I find Key card readers at stations?

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.

Travelcards, Oyster cards, and other networks

Can I load Oyster pay as you go onto my Key Smartcard?

No, Oyster pay as you go is not available on the Key.

Will The Key work in London?

Yes, you can now buy Season tickets for travel between stations in the London area. If you have a Travelcard loaded on your Key Smartcard you’ll be able to travel to any London station within the Travelcard zone. You’ll be able to use it on buses, tubes, trams, Docklands Light Railway, London Overground and other National Rail services.

Can The Key be used on Gatwick Express services?

Yes, you can use The Key Smartcard on Gatwick Express services as long as you have a valid ticket that can be used on the Gatwick Express.

Can I use The Key Smartcard on other operator services?

Yes you can. You can use your Key Smartcard on any train service as long as you have a valid ticket to travel for that service on your smartcard.

Replacing and transferring the key

How do I get a replacement Key Smartcard if it is damaged, stops working, is lost or stolen?

If your Key Smartcard stops working, is lost or stolen, we’ll block the card and send a free replacement to your registered address. If you had tickets on your Smartcard, your replacement will arrive with them pre-loaded and ready to use. Just log in to your account to cancel and replace your existing smartcard. We’ll give you up to 2 free replacements over 12 months. Any subsequent replacements will need to be investigated and we may retain your Key Smartcard.

Whilst waiting for your new card to arrive you will need to buy paper tickets to travel. If you have a season ticket, we recommend that you buy a weekly ticket whilst waiting for your replacement Smartcard to arrive. Please keep these tickets as you will be able to claim a refund for them on receipt of your replacement Smartcard. Refunds will be processed at any Great Northern, Southern or Thameslink ticket office providing your Smartcard season ticket is active at the time of loss. A £10 admin fee will be applied to all tickets as per our Smartcard refund policy.

Is my Key transferable to other people?

No, your Key Smartcard is not transferable and can only be used by the person it was issued to. For your own security, your Key Smartcard will be retained if someone else other than you is found to be using it. If your Key Smartcard is being used fraudulently then those involved could be liable for prosecution.

Refunds and compensation

Can I claim compensation for delayed journeys when travelling with The Key?

Yes, if your train journey is delayed by more than 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.

To claim compensation and for further information about Auto Delay Repay, please visit our Delay Repay page. We can also automatically notify you when we think you’ve been delayed. Just tick the box for Automatic Delay Repay in the preferences section of your online account.

How can I get a refund for my key?

Log in to your online account and follow the prompts or visit our refunds page. We will contact you within 28 days of receiving your request.
