how to program a new key fob

[Sam]

Background:
----------
My key fob stopped working , I assumed it was just the battery.
I was in the shopping center the other day and being lazy, I gave my key fob to the Mr Minute dude to replace the battery.
When I got it back, he said it wasn't the battery and claimed the Key Fob was not working.
I took it home and opened it up, and I found the circuit board was badly scratched and the internal metal battery holder was all twisted and broken.
I assume he broke the bloody thing !.

The Problem:
-----------
Anyway, I decide to purchased a replacement one.
I put the old key into the new Fob so I don't need to get a new one cut, but now I need to program the new key to work with the car.
I search the net but I haven't been able to find anything that helps.
Does anyone now how to program the 147 Key?

Some time ago I purchased a spare fob from a wrecker for my 156 - it was reasonably cheap and I got it just for the plastic bits, as a spare. I recently bought another 156 and it came with two fobs, one had been immersed in water and the battery holder was corroded as well as a couple of tracks on the PCB.  The PCB was also scratched where the battery holder metal 'tongues' touched the PCB. I could repair the corroded PCB, and swap over the battery holder and it works.  Maybe you can get a fob from a wrecker and change over the battery holder if that is what MR MINUTE ruined ?

p.s I think would be very difficult to reprogram the fob - I had thought about options if I could not repair the PCB on my Fob, and the next step would have been to go to a PCB surface mount specialist and get them to swap over the surface mounted integrated circuit(s) from the corroded PCB to the PCB of the spare fob I bought.
