Alarm and remote central locking
I recently got a 2000 Alfa GTV v6, which I'm absolutely loving. However the remote central locking does not work.
When I press the button on the key, it flashes so I presume the key is fine. No green light illuminates on the receiver though.
I've been attempting to unlock the receiver, but no luck so far. I found a 4 digit code that was attached to a bunch of keys I got with the car, that doesn't work. I've also tried 4 digit codes that are stamped on each of the keys, but none of these work either.
While I drive I also had the alarm light flashing, which I believe is to tell me the alarm has been set off. Pressing the button on the key while its in the ignition does not clear this.
In an attempt to clear the light, I disabled the alarm with the switch under the bonnet, then enabled it. After a couple of seconds the alarm blips, then goes off for about 15 seconds. This happens even if I enable the alarm with the ignition key one click forward.
So I can't program my key to properly activate and deactivate the alarm, and I also now can't enable the alarm now without setting it off. What's going on!?
