Cheap crummy entry door lock. Any good ones?

I bought my current rig last May. The keys were missing and the guy gave me some copy of a copy of a copy that he said would work.

Well, after fighting with the thing to get it to work, I just wandered down to an RV parts store and bought a whole new door lock / deadbolt assembly.

Ever since day 1 the thing has been difficult to operate and I have to fiddle fart with key to get it open. And then the key sticks. Hard to get in hard to take out. Yes I oiled it.

I got to get the TT from storage last Sunday and I managed to get the deadbolt open but no way the latch lock would give. Grrrr. Gal at my storage place was standing beside me. Let me try she says. I step back and say have at it! She finally managed to get it open.

With the door open I lock it and try again. The whole lock cylinder fell out of the door.

What a piece of junk! Less than a year old and it is garbage.
Brand name on the inside of the door lock says FIC. Only marking on it aside from Lock Unlock!


So, question is:
Are there any decent manufacturers of door lock assemblies?
Or are they all the same pile of junk?

I need to get another new one but want something that actually works and I don't have to stand there fighting with the key.

I actually have to replace all my outside locks. They are all hard to operate.
