What is this "key mod"? The solution I saw was not a new lock
cylinder, it as a replacement detent spring and plunger to make it
harder to turn the ignition switch from one position to another. Had
nothing to do with the key.
The problem was weight on the switch. The key modification makes a
smaller hold so it will fit on a ring, but makes it harder to hang
your purse, grocery bag and laptop like some people do. The added
weight of a dangling bunk of stuff caused the switch to fail.
GM says it is best to use just a single key in the ignition. Makes
sense, but reality is, may people have hefty key rings.
I know that's what GM says you can do but it is not the "fix". At
least it wasn't what was shown on the news as the real fix nor is it
what the Chevy dealer did on my 2000 Malibu. They did not give me a
new key, it was returned with the same old key but presumably with a
stronger plunger. Where do you get the info that this "key hole
thing" is what the official repair is when you bring a car in for a
recall? Was one of your cars recalled and they gave you a new key
with a smaller hole?
