mk 2 galaxy Key pat programimg

[robc]

Good afternoon all,

well one issue resolved and another one pops along 

The fey fob will not work to start the car, I have the factory spare key and the plastic valet key, both start the car fine, look up on the reference section done the sequence ! key in the off then the other key the the remote fob key, but nothing works, when it goes into program mode does the door led's stay on? or like old focuses is the a beep? as if its supposed to do something to tell me its in programing she's telling me nowt! oh the pat chip was lost so EBay one was bought with DI44, although for the life of me I cant see what's actually wrote on the chip it's self .

Thanks all!

The transponder chip out of my Galaxy remote key is made by Philips and has the number PCF7935DS on it (you need a magnifying glass to read it though!) - exactly the same as this.

Thanks for that ! Yea mines not a Phillips chip
An doesn't seem to have the same number on it, got it off eBay have messaged the seller but as normal doesn't seem to be responding to question !!

Hm, well as well as I can make out from your picture that chip looks very much like this (with the same number by the looks of it) - in the description for that chip it refers to cloning so maybe the chip you've bought can only be cloned from another key, i.e, it doesn't have a unique signature allowing it to be programmed in it's own right? This would explain why you can't programme it normally.

Hmmm are right! well that would make sense, so is there away to program an cloned chip?

To the best of my knowledge it's done by a locksmith using a special machine to duplicate the transponder signature from an existing key, it isn't something you can do at home.
