Beginning in 2019, Kantech is no longer manufacturing fobs that look like this:  XSF (01) 78:6430   All fobs now look like XSF 0285:14638, and require a software upgrade to activate.  

Should you wish to continue using the original configuration, without a software upgrade, we can offer you our RapidPROX® for Kantech fob.  It looks the same, works the same, and has the same LIFETIME WARRANTY as the genuine Kantech fob - and less expensive too. Click on the lady below.
