Stopped by the shop on my way home yesterday, it took him 5 sec to get the tumbler out and another 5 sec to put in a temporary "shop tumbler" while waiting the matching one to come. He also mentioned considering changing the steering lock and igniton switch because they might go bad dut to the age, and it will cost additional $200, and the new tumbler I put in will be wasted if this does happen, is this correct?
