— 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 0. 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.
The card is recovered from the conductor's Briefcase by combining the Gold Ring and Silver Ring and using them on the lock.
