Question about pal card key in the torture room...

[ahln1239]

How snake, after being tortured, was able to get the key again?
and why ocelot has told liquid that snake didn't have any keys on him near the end where ocelot and liquid spoke near metal gear rex...?
was it to fool snake? if it was, then it's not smart! because snake knows liquid took his card in the torture room...
thanks!
