"...An off topic reminder - BEWARE of heavy sets of keys -- they can cause expensive damage to ignition switches on steering columns. It can sometimes take years but WILL cause it. Know a guy who did it twice and finally learned his lesson, one costing $700-$800...
You know, I have always heard that. But, I have always carried a lot of keys, my ex still has a '75 Toyota P/U that we bought new, I drove it over 15 years on a daily basis, and the ignition switch still works fine. I drove an '89 Ford P/U for over ten years, same thing. Still have a '98 Nissan P/U...
I won't say it can't happen, it has just never happened to me...
