Thank you !
This is comment I got in the different forum:
"Until you can get a new lock barrel or handle, yes, I'd go with the preventative measures for the mean time; steering lock, leave glove box empty and open, possibly even take out rear parcel shelf?
Late mk3's have built in immobilisers in the key, you can tell if they're much chunkier and look like they can be split open, also if they have a little torch light."
My key indeed has little totch light, however I can see no indication that immobilizer works, e.g. I cannot see any lights flashing or anything.There are sensors inside on the both sides of the widescereen.
I wonder how much would be to fix the lock and whether it is worth to contact insurance company that would probably send my non claims bonus attempts down the drain...
