We have been offered a trade account by xpart and so we could supply Pektron fobs if people need them.
We have tested the very cheap red ones, and they do appear to work. The checksum in the bar code that they supply is wrong, but pscan will correct it.
I was told they they don't last that long though.
The big advantage of the original MG Rover ones is that they automatically disable the immobiliser when you turn on the ignition, so no need to press the button before starting the car.
Lastly a reminder that pscan can only code in brand new, unused Pektron fobs that have a 22 digit bar code.
Used ones will not work. The code rolls outside of the acceptable window once they have been used a few times which make the 22 digit bar code useless.
