Picked up my new chrome key today (car only came with one that would start the car, other just opened doors, so dealer paid :D).

Anyway the new chrome key unlocks all the doors on a single press whereas the old plastic key does drivers on press one and all on press two. Not a problem, as I if I'm on my own I often have a laptop bag or something that I want to bung on the back seat, and after four weeks I still haven't got used to the need to press the key twice.

Anyone else noticed this when getting a new key?

Implies there are different types of unlock codes that the key can send. I was thinking that as the DAS unit knows about 8 possible keys the "slot" for each one can be programmed differently - however I don't think the DAS unit is involved in the unlock process (only in the ignition/immobiliser).

You should be able to program the key for 1 or 2 presses to open all doors.
Check your handbook, I think you press lock and unlock together until red light flashes? I did it with mine anyway, cant remember exactly how.

I usually have 2 laptops - don't ask.! They reside in the boot. Also, the doors auto-lock above 5mph..ish..!!!!!!

You are correct - just done it (had read though the handbooks generally when I got the car, but didn't notice this).

Thanks

LOL - How did you guess..!?
