Learning about Keys and Locks, Wafer Source and Questions Options

[Highland]

With the exception of the front trunk lock I've had to reconfigure the wafers in all my locks to get the key to turn smoothly. Everything has been keyed with the black key, the red key seems to not be for this car.

I'm working on the ignition key now and the key turned enough to start the car, but sometimes would catch and require a little wiggling. After opening the assembly, I notice some of the wafers stand slightly proud above the cylinder.

Does anybody know:

1) Do the wafers wear over time and I actually have the right wafers?

2) How many wafer types are there?

3) These wafers on ebay match dimensions. Any opinion if these will work on our cars?

I don't understand the roll pin question but the set screw on the side of the tumbler goes through the hole in that little ear on the side of the switch to hold the switch in the tumbler. The tumbler is just a mechanical connection to the switch. It simply turns the the inner piece. The spring action is inside the switch to bring it back to run position after start. Your old switch is just worn out.

I was referring to the roll pin holding this assembly together.

Is it to act as a stop for the key too?
