The KWICKSET contemporary, matte black finish, low profile round "Uptown Deadbolt" featuring Smart Key (# 25B-RDT-514-SMT) took about 20 minutes to install following the step by step instructions along the printed guide and the online installation video. Once installed the minimalist yet chic Uptown Deadbolt was not only secure and sturdy but also functionally smooth. In addition, being able to re-key the lock to any KW 1 key in under a minute is extremely convenient.
