Rocker Picks

No pick will open "all doors and trunks". Rocker picks definitely won't; they won't work on anything with a paracentric keyway, and they're of extremely dubious value on others. Basically, a rocker pick is just a variation on a rake, and raking is generally not a very effective way of trying to open a lock.

There are specific applications for 'em where they may be effective enough to be work considering... or may not.

No. Yes. You're welcome.

No. As will usually be the answer to any such question containing the word "all".

Any exceptions? Thank you,

Lots.

For what it's worth the true rocker picks which are configured as a double ended pick work alot better than the "jigglers" which are configured as a flat more or less GM appearing key, which are junk.
