I just got the car. I do have a heavy keychain, but here the problem is electrical, and the switch is at least 4 inches away from the key, when inserted.
The car runs fine, but none of the accessories work, because of a bad contact. Unfortunately, it happens to include the windshield wipers, which must pass inspection, as this car needs it, so I have to fix it. I managed to pull out the switch yesterday, but all I was able to do, was break/bend the housing open, and get it to where the car won't stay running.
I have to call the dealership first, to get a price. Then I'll go find a used one.
Otherwise, if I can get the switch to allow the car to start, I can hotwire the accessories.
