The immobilizer isn't recognizing your key. You need to reprogram your keys to your car. Unless you know the SKC and know someone with VAG-COM you are going to have to go to the dealer.
Did you try all the different keys you have for the car? If you are lucky only one key is bad and you can drive to the dealer and get the bad key reprogrammed or buy a new key and have them program it to you car. Otherwise, you are going to have to get towed.
If it is just one key, make sure you bring all the keys to the dealer so they can do the reprogramming correctly.
Was any work being done on your car to cause this?

So jus wanted to comment on a solution that worked for my case and may help others like it. I decided to change the battery on my girls key for her 01 vw jetta next thing I know she can't start her car after trying everything I notice the immobilizer sign was on I did some digging and realise that the key was the issue. I did not put back the transponder. But even after I did it still didnt work. I looked up this issue and at first I thought I needed to re program the key . To do this I needed a second key which we did not have. Then I read about recharging the battery here . Unfortunately I did not have a charger. So what I did is I left the key as on connected jumper cables to my car and left my car on for 20 mins. I came back I tried again to start up her car and it worked the light was gone. No need for a 2nd key or battery charger. Again this worked for me may or may not worked for you but if it does it beats money spend at the dealer best of luck.

Try leaving the ignition on for 15 minutes

Try hooking up a battery charger and turning the key to the on position and leaving it for 20 minutes. The immobilizer light should turn off. If not just wait longer. It could take an hour.

Check the dash connections and faults in the dash ecu.

SOURCE: electronic immobilizer
most likely cause is the gauge cluster, this will have to be tested and service by your local dealership because the dash cluster and keys have to be coded. I have seen the immobilizer loose it's coding for apearantly no reason. therefore have them recode cluster and see if problem goes away, if it doesn't the gauge cluster will have to be replaced.
