Just to close the loop and in case anyone ever getsbthe same question as me. My car is a 2.0i from 2004. Very basic model as I needed an A to B vehicle, however now fell in love with Subaru brand and will be importing one from Japan this year, a Legacy Spec B!!! My current car though, it has a key with 1 button only, which works to close, open the car as well as open the boot and an ability to trigger panic mode (anti theft). It also has an immobiliser. Here's how it all works: Unlock - press a button once Lock - press a button once Open boot - when unlocking the car you have to hold the button until you hear the boot mechanism unlock Panic - when the car is locked, press and hold the unlock and then press lock for 10 seconds. Immobiliser: once you come to a stop and want to switch the car off, switch off the ignition and pull the key - immobiliser should automatically engage by default and a red key flashes. To start the car, put the key and switch ignition on but don't start the car, now whilst the key is in the ignition, press the unlock button and start the car. That's pretty much what I've learnt during the weekend. My car key battery was nearly dead so wouldn't respond to me pressing the buttons every now and again. I hope this helps. Will crawl through the forums to find out what upgrades I can get in the future once I get my hands on a Spec B.
