MUTEX MX800 Mechanical Keypad Door Lock with Key

MUTEX MX800 is a mechanical keypad door lock with key entry, positioned for home, office, garage, and other access doors. Its listing describes a battery-free design with changeable push-button combinations, but it is not a deadbolt and its fit depends on the door thickness and backset.

At a glance

Mechanical push-button access uses an 11-digit keypad, and the combination can be changed with a flathead screwdriver.
The listing says no batteries are required and describes key access as included.
The product is specified for doors 1 3/8” - 2” thick with a 60mm (2 3/8") backset latch.
The manufacturer states that fitting a standard pre-drilled 2 1/8” USA door opening requires drilling one 10mm (25/64”) hole.

What to know before buying

Listing details to confirm

The lock is described as fitting doors 1 3/8” - 2” thick with a 60mm (2 3/8") backset and not a 2 3/4" backset. The listing says installation in a standard pre-drilled 2 1/8” USA door hole requires drilling one 10mm (25/64”) hole. It is not a deadbolt. The listed control method says App, while feature copy describes mechanical, battery-free operation and says an app is unnecessary. Confirm what control method applies to this model before buying. The keypad combination is recommended at 4 to 8 digits. Although the listing claims three sets of keys, the explicit contents list does not mention keys, so verify the selected listing.

Frequently asked questions

Does the MUTEX MX800 need batteries?

The feature listing describes it as mechanical and says no batteries are required. A separate control-method field lists App, which conflicts with that description, so confirm the control setup for the specific listing.

Will it fit my door?

The listing specifies doors 1 3/8” - 2” thick and a 60mm (2 3/8") backset latch. It says it is not for a 2 3/4" backset and that standard pre-drilled 2 1/8” USA door holes require one additional 10mm (25/64”) hole.

Is the MX800 a deadbolt?

No. The product information explicitly says it is not a deadbolt.

Are keys included?

Feature copy claims three sets of keys, but the explicit included-components list does not name keys. Check the selected listing before relying on key access being supplied.
