Why does every scripted door in my game open extremely slow but everything else works?

I scripted keycard doors, keycard gates, and automatic opening doors. When I stick the card into the keycard door, it states that it was access granted like it is supposed to but then slowly fades to its transparent state. It takes about 2-3 minutes to open to finally let me through. This applies for every scripted door including the gate and automatic opening door. I just thought that my game was lagging but my scripted screens and machines work perfectly fine and do not lag. I need these doors to open at a regular pace how they used to. They just stopped working for some reason. Can somebody please help??!!
