Right, I've got a 2000 GTV v6, and i'm trying to pair my key to the remote central locking receiver. Long post, but hopefully you'll see I've tried a lot.
My remote central locking does not work, and when I use the alarms "emergency" key and switch it to on, the alarm goes off (it appears to have been activated - and due to not having remote central locking I can't deactivate it)
So, I followed Barry's instructions on reprogramming the receiver. I used a GQ-4x willem programmer from MCUMall, and got a SOIC8 test clip from ebay (means no soldering and I can read and write the 93LC46B eeprom on the board - ideal). BTW I'm in Bristol, and if anyone wants their receiver read/written I'm more than happy to do it.
From here I managed to get the 4 digit password to "open" the memory on the receiver so that I could do "simplified programming". This worked a treat.
However, when it came to pairing my key - the receiver refuses to accept the key. I hold the button down on the receiver, press the button on the key, it goes from flashing to a solid light (meaning it has received the signal and the key is not faulty), I let go on the receiver and wait for the 6 flashes to tell me its all done, sadly I just get another solid light - and when I read the memory again there is no change.
So I think this has to do with the alarm. It states in the instructions that the alarm has to be on, and deactivated. I can only have the alarm on, and activated or just plain off.
I've also tried loading up virgin hex to the eeprom, but still no luck.
So what are my choices?
- deactivate the alarm via some other means - there is mention of an "Alfa Romeo Tester" you can attach to the alarm, does anyone know what this is? and if it can deactivate the alarm.
- reprogram the alarm - can i rip it apart and load up some virgin hex?
- reprogram my key so that it matches what's in the memory of the receiver - how do I do this, its a PIC and I'm guessing there is copy protection on it?
- try programming another key in using a hex editor - I have a 4 digit code on a scrap of paper, that I guess is to do with the key I'm trying to pair. Unfortunately turning this 4 digit code back into hex yields several 100 combinations.
- get another alarm plugged in, that when I turn on isn't activated, in the hope I can do the normal "simplified programming" procedure
Anyone, any ideas?
