Anyone know where I can find door lock cylinders and keys for a 1965 dodge Coronet?

Ebay (likely), www.classicindustries.com (maybe). I'm thinking these are the ones with the big round chrome face? (65/66 was the changeover year to the later small face ones but the innards still interchange). With a new cyl you can take it to a locksmith and match your ign key to it or if you have spares with the removeable rectangular chrome covers you can mix and match tumblers/spacers till any key will fit. The tabs on the chrome covers are brittle so bend them carefully just enough to get the cover off. You get the total height just right on all holes so the cyl will turn and even if you are short on parts and you leave several holes empty not to worry as no one picks locks anymore (exc in the movies)

Thanks,do you know if the 66 will work on the 65?

1962-65 are the same. There was a major change in the door locks and keys in 1966.

I took my old one to a local locksmith and he got a new ones in a couple days. He made them keyed all the same as the ignition key. It was easy.

The ones in the pic (as stated) are the early ones with the peened cover which needs a locksmith to open em up to rekey. The later ones have the much smaller round non tapered chrome outside face plate and have the removeable chrome rectangular tumbler cover. EDIT The hole in the door sheetmetal is different between the two groups & cyls wont interchange (likely larger on the early ones)

I can rekey a 1966 and up door cylinder in about 10 minutes, while a 1962-65 cylinder will take me about 40 minutes. I have done the early locks for a few Moparts members. Also a lot of locksmiths will not even have blanks for the early locks as the grooves on the sides of the lock were different 1959-65. A well worn down early lock will sometimes take the later key blank.

try a NAPPA parts distributor...I ordered an ignition switch with keys...for a 1970 GTX....I had it the same day!

any luck finding these, I need one....
