Computer-cut Keys?

[dev070]

So I was walking through a local bargain store yesterday and I came upon a bike lock in the sporting goods section. What caught my eye was the strange looking key that came with the lock. Instead of teeth, the two wide sides of the key had two rows of various-sized craters. The narrow sides each had one very tiny crater as well. When I looked into lock, I saw what seemed like ball bearings protruding from all four directions corresponding to the craters on the key. The package only identified it as a "European Computer Cut Key" but I can't find anything on Google that resembles this lock. Does anyone know what I'm talking about?

Ah, what you're describing sounds like what's normally referred to as a "dimple lock". If you search around here, there are a number of threads with good photos of the keys and breakdowns of the locks.

Awesome, thanks!
