Ignition Key Problems
For starters, my apologies if there's an answer I couldn't find through a Google search. If someone has it, please post the link (or the keyword). That would be enough, thank you.
Otherwise, here's the problem: every morning when I try to start my 2004 500 CL, it takes me a dozen tries before the car recognizes the key.
Cleaned key and switch, nothing. Bought a new key from dealer, nothing: same problem. Changed batteries on old AND new keys. Nothing. Main battery is fuly charged.
The weirdest part is, when the vehicle has started once, it goes on and off all day without a hitch. Early next morning, the problem resurfaces.
If I lived, say, in Canada I'd think the temperature change might make a difference but in Miami we go from the 90's to as low as 72 at night.
So, should I go to a stealer & have it install a new switch or someone has a bright idea like check some connection that may loosen up at night?
