"This keycard is used to unlock the electronic door to the lead car."
— Item examination

The Blue Keycard, known in the Japanese version as the Blue Cardkey (ブルーカードキー Burū kādokī?), is a key item in Resident Evil Zero. It is a small security card that belonged to the conductor of the Ecliptic Express.


It is used in the second car passage; disabling the electronic lock grants access to the exterior corridor.[1]


The card is recovered from the conductor's Briefcase by combining the Gold Ring and Silver Ring and using them on the lock.
