Can my locks be re-keyed?

[Number21]

So, my '73 didn't come with keys for the doors. It did come with two seperate gas keys, an ignition key, a canopy key, and a lug key. My other '79 has door and ignition keys, as well as 2 more gas keys. And I have a Jeep that uses GM keys. In other words I have too many damn keys that all look the same!

So I was thinking...would it be possible for a locksmith to modify the lock cylinders in my '73 so that the keys to my '79 would unlock both? Or would I have to buy a new matching set of four cylinders and change 'em out?

small key chain for each or some Paint so you can color coat them

Yeah, I've tried seperating them, but, inevitably I never have the right set of keys on me when I need 'em. Add another dozen keys or so for the house and my shop...3 more keys for my mailboxes. I feel like a freakin' janitor.

yes you can get the keys done the same but $$
as you would make your life easier to pick a car key so could a thief have his choice made easier.loose one and somone could take them all.
i use two sets a main and a sub set
main has all keys i could use
sub set has 4 car sets keys and house keys and remotes
and the use a carabener to connect it all
the lighter the keys the easier on the ignition
