Getting the key

Can I transfer my paper Season ticket to my Key Smartcard?
Yes, as long as you have at least one month’s validity remaining 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. Unfortunately it is not possible to transfer your Season ticket if it has been discounted.
To transfer your ticket:
- Check that your origin and destination is available on The Key Smartcard by checking the map
- Apply for The Key Smartcard online
- Visit any staffed Great Northern, Southern or Thameslink ticket office outside of the London Travelcard area. See our map
- We’ll then contact you when your Key Smartcard is ready to be collected, usually within 5 working days

Registering the key
What details do you need when registering for a children’s Key?
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.
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 Smartcard?
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.
What happens if my Key Smartcard stops working or my card wasn’t read properly when I touched in?

Where will I find Key Smartcard 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.
