What is the Warranty on AuthAnvil Hardware Tokens (keyfobs)?

CryptoCard KT-1 and KT-4 key fob tokens have a 5 year warranty that we honour if:

  • The token was purchased from us 
  • The token failure wasn't caused by abuse or misuse 
  • The token is less than 5 years from initial purchase date
  • The failure is reproducible or evident on the token

If you have a defective token that is covered under warranty, we can exchange or replace your token through our Return Materials Authorization process.



If you have any questions or need some help, we would be happy to assist. Open a case at or send an email to
