In TV land, some 90% of locked doors can be opened in seconds by following three simple steps:
- Insert a credit card between the door and the frame just above the lock.
- Jiggle card a bit.
- Turn handle.
Up to a point, this used to be Truth in Television. Early spring-bolt locks could be circumvented with flexible strips in a similar way (though actual credit-cards are usually too stiff for the purpose), especially if carelessly installed. However lock manufacturers introduced features to prevent this kind of attack a long time ago, and dead-bolt locks were always immune to it. As such, it's a Discredited Trope.
- Given that Barclays Bank used the advertising slogan "a Barclaycard gets you anywhere" and had several ads featuring a James Bond parody,note it's an odds-on bet this trope would come up at least once.

[Art checks his wallet to find that all of his cards are fused together after his Harmless Electrocution moments prior]
Ray: Never mind. [pulls out a store credit card of his own and sticks in into the door frame]
Art: I didn't know you knew how to do that.
Ray: I DON'T know how to do this. [card breaks]
Art: That's a shit store anyway.
[Ray picks up a rock, breaks the window on the door, reaches inside, and unlocks the deadbolt.]

Unwilling to reveal the real answer (which involves bribery) Morse attempts to use this trope as an explanation:
"You see, the lock on the back door there's a Yale, and with a Yale the bevel's always facing you when you're on the outside. So if you take a credit card and slip it in, you'll find it's just strong enough and just flexible enough to"
"I know, sir. I've seen it done on the telly."
"And the lock on the back door there isn't a Yale, is it? Goodnight, sir."
