I had a minor traffic accident last night where some opportunist stole my laptop bag, which contained work laptop and GT86 car key, whilst I was exchanging details with the 3rd party. My insurance company reckons I should change the locks, they haven't said whether I should change the codes yet but their theft dept is closed until Monday. However I just rang the Toyota dealer in Reading and priced up what would need to be done as a worst case scenario, which involves a new ECU, and it came to an eye-watering £2985 plus labour. Has anybody been in the same position? What did you do? Thanks John

Yes key fob. There is a key fob at large that could allow access to and start my car. My insurance policy covers £100 pounds towards the change of a lock set, about 3% of the total cost.
