replacement 147 keyfob can be made to work on the cheap
I've recently had some key fob woes, and thought I would share my success story with the rest of you. Be warned - it does involve some soldering...
For clarification, I am talking about the 3 button keyfobs - I understand there are 2 button ones out there too? For those who don't know, there are two parts to this key; the remote locking tranceiver, and the transponder (for the immobiliser). Both will work independantly of the other.
Some background info on my story -
I have two keyfobs that are paired with my 147. One of them hasn't worked for locking the car since I bought it, the other has worked for locking/unlocking, but not for the boot. Recently, the unlock button broke on the one that was working, leaving it basically useless.
I also happened to have a spare remote fob that was not paired with the car, but I had good reason to think was in working order.
I figured that it must be possible to take the neccesary components from the circuit board of one that was paired with my car, and put them on to the key that wasn't paired. A little internet based research netted me with an answer that I was 95% happy with, so I gave it a go - there was nothing for me to lose as I was using the paired key that never worked for remote locking as the donor.
Two hours and a couple of burnt fingers later I had my Frankenstein key. Long story short... it worked! I now have a fully working key.
I promise I will post a follow up with precise details (I'm at work at the moment, and don't have the photos or links), but I was just too excited and wanted to share my success with the crowd.
