I love the Master Lock
The Master Lock 5400D is absolutely perfect! It's easy to use, can hang anywhere inconspiculously, and even has a cover over the dial to protect it from the elements. I have the convenience of never being locked out or of allowing someone to come to my home by giving them the code. And the code can be changed anytime. It's called peace of mind, and the Master Lock has provided that!
Verified Purchase
This lock is real sturdy and you can store multiply keys in it. Very easy to set lock code. Would recommend.
Verified Purchase
Security Well Done
I purchased this lock to put the keys for my golf cart in the lock nice and securely. The leasing agent of my home was able to easily obtain the keys and take interested clients by cart to tour the home and area vs having to walk. The locked served the exact purpose we purchased it for.
