These are the two bands Bauer uses on RV entry and compartment locks. The same number is sometimes stamped with an RV prefix — RV301 and 301 are the same key. What IS different is the cut: the 300 band and the 700 band are not interchangeable, and the 700 band comes in both a single-sided and a double-sided version.

Stamped either "301" or "RV301" — same key, same cut.

The double-sided version — both edges of the blade are cut. If only one edge of your old key is cut, you need the single-sided version, which has its own page.
