Intermittent turn signal, radio, and power windows

This is my first post on Jeep Forum, but I've been reading ever since I got my 2000 XJ back in May. After some searching, I narrowed the problem down to either the ignition switch or lock cylinder. The guy who sold it to me said someone tried to break into the vehicle and ever since the radio randomly cuts out, the turn signals stop working every so often, and the passenger side power window switch stopped working.

The turn signals haven't been working for a while so today I took a look around the steering column. When I took the lock cylinder out, the turn signals came back. I noticed some damage around the cylinder (see pic), and the key feels loose. The video shows how barely touching the key starts and stops the alarm chimes.

Is this a lock cylinder or ignition switch problem (or both)?

I'd replace the cylinder since you know someone goobered it already. Check fuses, connections and such before the switch replacement. I've had all those symptoms from an alarm(not factory) Install that was done poorly.

Is the trim ring cover around the cylinder an important part? The cheapest I can find it online is over $20 shipped. Otherwise I'll just replace the cylinder and find a locksmith who can match it to my keys.

EDIT: Took another look at the cylinder and it's not OEM. No point replacing junk with new junk. Found all 3 OEM parts (trim ring cover, cylinder, and switch) on eBay for about $45 shipped. I'll update when parts are in and installed. Coincidentally, after messing with the cylinder yesterday, everything has been working just fine. But I know the next time I hit a pothole or bump the wheel/dash the wrong way the problems will be back.

Well it may be too early to claim victory, but I installed the new lock cylinder, trim ring and ignition switch on Monday morning and I've not had any turn signal or power window problems since. I'm still having radio issues, but I found pennies on top of the head unit when I took a look the other day...I'm guessing I'll have to crack open the unit and remove about $0.92 in change to fix the problem.

Question: If I unplug the head unit, will I need to get the "radio code" from the dealership to turn it back on?

Just wanted to follow up on this in case anyone was interested.

The stock radio was just bad. Replaced it with an Alpine CDE-134HD from Crutchfield ($115 shipped with mounting parts included) and no more problems.

The turn signal problem returned. Found this video, then got the $16 part (EP27) at AutoZone:
Problem solved.

I diagnosed the window problem to a faulty window lock button connection. This thread explains how to fix it (just need to resolder a connection):

If you don't need the window lock function anyway, a slightly easier method can be found here:

So, the ignition switch and lock cylinder most likely weren't the problem, but they were junk, and now I have decent condition OEM parts instead.
