Will a installed lock screen conflict with stock lock screen

[android jack]

So after I uninstalled an app I searched more apps by same developer and saw a few good ones and a lock screen among them. Its working fine but I'm worried might cause problems. So will it?

Usually, nope. 3rd party lockscreen apps, if still supported by your OS, do not conflict with MOST lockscreen, but some phones do have a habit of re-enforcing their own lockscreens, so you end up with TWO lockscreens. If this is not the case with you, then you should be fine.
