High Security Mailbox Lock Key Blank

Architectural Mailboxes no. 5143 key blank is designed specifically for high security mailbox locks. The key blank is used for making additional key duplicates, but it requires an existing key to do so. These special key blanks should be duplicated by a professional locksmith, as they are not compatible with automated duplicating machines.

Included in the package are four key blanks, all constructed of durable brass. When duplicating the key blank, be sure to take your existing cut key to the locksmith for accuracy.

To ensure you have the correct key blank for your lock, refer to our lock and key blank compatibility guide. This will help you find the right key blank to match your existing lock for a seamless and secure fit.
