Surface-Mounted Mailbox Lock

The Ilco 1703-81 is a vertical deadbolt lock designed for surface mounting on mail boxes and letter boxes. It uses a disc tumbler cylinder and includes two keys per lock. The unit is supplied in a box with a polished brass finish.

For Standard Mailbox Security

Suits owners who need a dedicated surface-mounted lock with vertical deadbolt action for a single mailbox compartment. Not intended for doors, drawers or cabinets that require a different bolt orientation or mortise installation. Buyers needing a keyed-alike set or a different finish should look elsewhere.

Disc Tumbler Cylinder

The lock operates with a disc tumbler cylinder, which determines the key profile and picking resistance. This cylinder type is the single specification that confirms compatibility with existing Ilco 1703 keys or the required key blank.

Questions about this item

Does the Ilco 1703-81 generate any noise or heat during daily operation?

No, the 1703-81 is a fully mechanical disc tumbler lock with no motor or electronics, so it produces no heat and no audible noise when the key is turned.

What mounting hardware must I already have to install this surface-mounted vertical deadbolt?

You will need appropriate screws or bolts for the door material and a drill to create the mounting holes; the lock body itself includes the cylinder, deadbolt and two keys.

Can the 1703-81 be keyed alike with an older Ilco mailbox lock I already own?

This unit is supplied keyed different with its own two keys; a locksmith can re-key the disc tumbler cylinder to match your existing key if the keyway is compatible.
