A couple years ago I bought a set of half-doors that needed a little TLC off of a guy in Georgia as a project for the future. I'm finally getting around to working on them. I don't know exactly what year they were from but know they are the earlier year TJ's because of the plastic track with door seals that slide into them. I think '97-'02 are those years, but not positive. One of the things I wanted to do was get the lock cylinders to match my keys. I know some think it's a waste to make sure the lock cylinders on half-door, or even full doors, are keyed properly on a Wrangler, especially when you run a soft top. I somewhat agree, but I just want them to match, that's really the only reason. My wife says it's my OCD.
I couldn't find a suitable locksmith in my somewhat rural area of SC, so off to the internet I went. I found the
Tumbler Kit on E-bay for $23 dollars. I also bought two black
Lock Cylinder Caps form Quadratec. The caps are crimped on and not salvageable. The paint quality on them isn't great so I sprayed a few light coats of Satin Black on them. There are different sized caps. I don't know the specifics of which years/style doors use what, but I know the full doors on my '06 have a bigger cap.

Here we go...

Remove the seal. I couldn't find anywhere that sold a replacement that looked like this one. Luckily mine were in good shape.

Remove the spring.

Pry the cylinder cap off. I got it started with a screw driver and then used pliers to peel it off.

Slide the inner cylinder out.

Push the tumbler/wafer piece towards the tiny spring and lift up. The springs are very small so look closely and don't loose them. This cylinder was gummed up pretty good with lube, so I had to move the tumbler/wafer towards the spring and lift with a pair of needle nose pliers. The other cylinder wasn't like that. Look at the tumbler/wafers as you remove them; they have a number on them. I made a little drawing on which number was in which position as I removed them.

I soaked the inner cylinders in some WD-40 for 15 minutes or so then scrubbed the inner and outer pieces with a small brush and finished up cleaning with some isopropyl alcohol.

I used all new tumbler/wafers but did clean up and reuse the original springs. The originals felt more springy than the ones in the kit. The ones in the kit were kind of weak feeling.

What you want to do is install the springs, then install the correct numbered tumbler/wafer so that they are flush with the inner cylinder when the key is installed. I started with the farthest one and just worked my way back towards the key. Installing one at a time and checking them after each one.

I put a light coat of white lithium grease on the areas of the inner cylinder that rotates in the outer cylinder.

Insert your key and turn it each way. Make sure the tumbler/wafers slide under the outer housing. If you can't turn the key, you've got an incorrect numbered tumbler/wafer installed somewhere.

Install the seal.
View attachment 113900
Install your cylinder cap. Line the 4 tabs up with open areas of the cylinder. Press the cap down tight on the cylinder and then bend the 4 tabs down onto the cylinder to hold it on. Make sure your seal is up out of the way before you crimp the caps down.
Don't crimp the caps onto the seals.

I don't have the cylinder cap on in the video. I put a few coats of paint on them and waiting for them to dry.
