The Key Smartcard
Answers to frequently asked questions on using The Key Smartcard when you travel in and out of London with Southern.
Getting The Key
Can I still get The Key Smartcard if I don't have access to the website?
Can I transfer my paper Season ticket to The 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 manned 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.

Therefore in some cases alternative fares may be available on paper. If you are making an online purchase you should de-select the 'Key Smartcard fares' option to see the full range of fares available.

Registering the Key
What details do you need when registering for a children’s 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.
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.
