Hi, i wanted to know if with a dslr (t3i) i could do a green screen technique and i would have a good result if its well lit.

Thanks in advance

As long as the screen and subject are well lit, you should be good to go.
I've done some green screen shots for a feature film I shot in 2014, called L'EXPERT.
Ended up with great results, but the shot was kind of back lit, so easier to key.

Yes, you can. That doesn't mean you will. Eight bit 4:2:0 puts a premium on your technique. IOW, it's easier to get a good solid key with more bits and more color, so 10 bit 4:2:2 would be easier. But it's certainly possible to pull a good key with a T3i. No doubt there's plenty of examples of this around the 'net.
 
If it's 4k 420, it should definitely be good enough. Good 1080p 420 (e.g. with an a7S or C100) is kind of OK but not great. Canon DSLR 1080p 420, I wouldn't say that's OK anymore in 2016. Just yesterday I watched one of my old T2i videos and I just couldn't believe I once thought THAT looked good. We've come a long way since 2010!

You can definitely do it, and if you're really good it may even look nice. With me shooting and keying, it would look awful. YMMV.
 
I used to work with some people that used that as their primary camera, and they did a lot of green screen shooting. Their keys weren't as clean as I'm used to, but it worked. Extremely even lighting is needed, and don't skip the back lighting. Of course other setups can do better, but the specific phrasing of your question tells me you might already have a T2i. If that's the case, there's no point in asking this question. If it's the camera you have, you make it work as best you can. What that means depends on you.
