Arco Key Blanks

Arco is a replacement parts brand for marine and equipment electrics, and its ignition switches take a small number of common keyways rather than one proprietary profile. That is useful to know when ordering, because the blank you need is decided by the code stamped on the original key or the switch body, not by the brand on the boat.

If you are matching an Arco switch, read the keyway code off the key or the lock before choosing a blank. Every blank we list carries its own profile and cutting detail on the product page, and we cut to code rather than to a picture.
