I forgot my unlock pin to my Galaxy S5 and Android Account Manager won't let me reset

I setup my 4-digit pin to lock my S5 and now pin is not unlocking my phone. When I tried using the Android Account Manager as suggested. I went thru all the steps, my phone was located, I hit lock, entered new password and confirmed, but then a box popped up telling me that since I already had a lock on my phone, Android could not help me. I have not seen anyone else with this problem. Is there a way to unlock my S5 now?
