Attempted Theft 300 zx TT Auto

Hi There,

I recently bought a 300zx for near enough nothing because the prevous owner had blown the head gasket, I booked it into the garage to get this sorted, but where i live its all residents permits and im waiting for a letter for proof of address to get mine, so i parked my car about half a mile away (free parking) and some ******* try to steal it, they broke in, riped the key part of the ignition, lock, steering lock and left a right mess, i know this is common on the car, the problem is that it had an immobilser where you have to click it forth and back a few times in a combination to start it, im worried that if i take it to someone to repair it , it will cost an arm n a leg, any suggestions, on maybe a key less lock, that would be cost effective and secure and a cheap cat 1 to satisfy the insurance company?//

please let me know
