Thankyou … I appreciate the seriousness more fully now, so would I be right in thinking that I have to keep trying with the method on the pscan site page until I get it to work, my EKA for the TF is 7566, my EKA code for my ZS180 is 2527 and my friends TF is 2528 … pointless to give you these numbers I know but should I change them using p-scan to something with less key turns like 4321 as suggested on the forum? Would a stethoscope be of any use to listen for a sound indicating the key turn has engaged? … I’m in Australia, the TFs have a 315 MHz fob over here and the ZS has the 433 Mhz fob, is that of any significance? Thanks Daryl
