The original key for the truck doesn't work very well you have to shake it to open and start engine. No need for expensive dealership replacement, go to a locksmith shop and have them make a copy of the key but ask them to raise the machine a fraction of an inch. This works and made a key that works great and you can make normal copies of this new key.
Ignition key wears out, but when replaced with newer key -- won't work in ignition. Must replace entire ignition?
