Tear down of an Electronic key  from Electronupdate:

In the mid 1980’s a company called Dallas Semiconductor was producing a wide range of small RAMs with integrated battery backup. One of the more unusual item was an early attempt at an electronic key: a user would be issued a key which could then be typically used to allow access to equipment and to keep track of usage. Not very secure by today’s standards…. but an interesting data point.
Opening it up shows that it had two major parts: a silicon die and a battery. The amount of ram on the die was very small, 256 bits!

More details on Electronupdate blog.

Check out the video after the break.
