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.
To transfer your ticket:

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.
