When you unlock the door a two tone alarm goes off. Put the key in and turn and the radio comes on plus lights, but it will not fire up the engine. Have opened and closed all the doors. What next?
Try pressing the lock and unlock buttons on the remote, holding for a few seconds, then trying the unlock and lock buttons to see if the alarm disarms...your description indicates the car alarm is still armed!
Testimonial: "Thank you, jimharri. Tried that, it didn't work. Had the AA man out who thinks it is the immobiliser. Can't override it, though."

I found a thread - http://forums.vwvortex.com/zerothread?id=1542461 that details the repair of the soldering on the key lock door module. Our 2000 new beetle had the same issue. Also sometimes it refused to start. Soldering pins fixed it all.
Also see http://forums.vwvortex.com/zerothread?id=1015107 for releasing window from track, And door handle from inner panel.
I ripped the door apart and re-solderd the pins. I only had one pin with cracked solder but two others looked thin so I did them while I was in there. It's about a four or five hour project if you have all the tools. (8mm triple square also called an 8mm internal was the hardest to find - Also needed Torx T8 T10 T15 and T30 plus Philips Screw Driver. )
Project is difficult but not too bad for the mechanically inclined. A 7 on a scale of 10.
Since re-soldering pins - no more issues! My guess is that a VW dealer would get $200 for a new moduel plus 5 hours of service time for this gig - easily a $500 to $1000 bill. My cost - several new tools - about $25.00.

If your car has an alarm with a separate remote, it is a separate system and it is probably self-arming. When you lock the doors with the key central lock, the alarm gets armed by the RAV4 being OFF and the door locking action. When you unlock the doors with the key, the alarm is still armed because the key is not comunicating with the alarm just the cars factory keyless system.
