Cabinet key S102 (fits Seeburg SMC1 models and up).  There is a lot of confusion over this key, Seeburg only used this style lock for this key number and for these two models.  IT can easily be confused with the DUO S102 wallbox key or the S102 office desk key.  This is the key you need for Seeburg SMC1 and SMC2.  If you need a DUO S102 key we have those just not listed.  Ask Sales same price as this key.
