I spend four hours trying to install the dual cylinder dead bolt lock. The problem is the two bolt screws that attached to the other cylinder dead bolt. After tighten the two bolt screws, I wasn't able turn the strike bolt with the key. After loosening the bolt screws the key was able to turn freely. However, the cylinder lock was loosely fitted around the housing that holds the cylinder is unsecured. My conclusion there is a defective design issue with this lock. I can not recommend this product. Buyer beware. Cheap price comes with a price.
