An update for those of us silly enough to live in the wrong hemisphere. The Technozen site says that only 433Mhz fobs can be supplied, not our 315's. Drat.
A local locksmith has obtained a new 315, with 22 numbers, for me and I look forward to coding it with my new pscan. Clayton has a Pektron.
By the way, I was also silly enough to ask Pektron if they might be able to make some fobs. Not as silly as it sounds - they boast about making a wide variety of fobs and I thought it possible that minor changes might make one compatible with TF's. Guess the (very quick and polite) answer.
