English to Spanish Other Other Locksmithing

Hello,

I'm translating a book about a secret agency trying to solve a mystery. In this scene, one of the members of the agency is trying to break into a house. He has some tools to open the lock, and I can't find a term in Spanish for this one.

By now I have paraphrased it into "dispositivo de forzado de cerraduras activado mediante disipador", but it's mainly a description of how I understand it works.

This is the paragraph of the source text:

He examined the lock set into the plate just above it: a simple five-pin residential lock. Beyond the exclusive and elaborate electronic locks guarding the main building, the actual locks on the individual doors were laughably inadequate. But that was what security did for you; it gave you a false sense of safety. He took a slim leather wallet from a pocket and opened it to reveal an array of lock picking tools, including a locksmith’s trigger activated picking device. He considered utilising the latter, then decided on a simpler approach.

Does someone know if there is a term in Spanish for that device?

Thanks in advance.
