What Customers Are Saying

The mailbox lock is generally easy to install and provides a good sense of security, though some users reported issues with the included components not fitting their specific mailbox. The lock is a cost-effective solution compared to hiring a locksmith, and it appears to be a durable product that functions as expected for most users. However, careful measurement and checking compatibility is advised before purchase, as a small number of reviewers experienced problems with the fit or durability.

The biggest shortcoming is the fact that the keys cannot be removed when the lock is unlocked. I also had to bend the retention clip in order to get it to hold the lock in place. If you buy this, plan on do...
