Ignition Lock Cylinder Going Bad

[pavementprincess]

I've been having a problem with my ignition lock cylinder on my steering wheel jamming up lately and I don't wanna risk getting stuck somewhere. I did put a little graphite in it since the last time it jammed and it does seem to be better, but having just recently bought this truck and it having 200k+ miles on it, I'm just gonna replace it and be safe than sorry.

Anyone have any brands or any they prefer, or should it not really matter?

Thanks!
