New to Me '70 Blazer

[Lawdog880]

I just picked up this 1970 Blazer from my father in law. He was the 2nd owner, making me the third. 👍🏻 First things first i want to install a new ignition and all new door locks/handles. My question is about getting all of these to use the same key. I went on LMC and saw all the parts for the ignition w/keys, but couldnt quiet figure the easiest way to get the doors keyed the same. If at all possible. Just throwing to you guys first, cause i am sure you all have been there done that. Looking forward to starting this process! Thanks for ANY help in advance!
