This Boca Raton project involved removing an older mortise-style lock system from a pair of entry doors and converting the opening for a modern, fully mechanical keyless lock. The replacement keypad operates without batteries, an app, Wi-Fi, or a power connection.

Project Overview
The original hardware used a larger mortise preparation inside the door. Removing that system left multiple openings that did not match the footprint of a standard modern lock. Installing the new lock therefore required more than attaching a keypad: the door preparation had to be evaluated, the unused openings covered, and the new locking hardware positioned so the latch, handle, and strike would operate together.
- Location: Boca Raton, Florida
- Existing hardware: older mortise-style entry lock system
- New hardware: mechanical keyless keypad lock with key override
- Power requirement: none—no batteries or electrical connection
- Door type: double entry doors with an existing oversized lock preparation
Before, During, and After the Mortise Conversion



Why a Mortise-to-Keyless Conversion Requires Planning
Mortise locks use a large pocket inside the door and often have a long exterior trim plate. Once that hardware is removed, the remaining cutouts may be wider or positioned differently from the holes used by cylindrical locks and many keypad products. Cover or conversion plates can provide a clean mounting surface, but their dimensions, fastener locations, and relationship to the door edge must be checked before installation.
The new hardware also has to align with the existing strike and the inactive door. A keypad that appears correctly mounted may still bind if the door pair, latch, or strike is out of alignment. For this reason, we check operation from both sides and confirm that the door closes and locks without excessive force.
Why Choose a Battery-Free Mechanical Keyless Lock?
A mechanical keypad can be a practical option when a customer wants controlled keyless entry without electronic maintenance. The code is entered directly on the lock, and the mechanism does not depend on batteries, a mobile application, wireless coverage, or an internet connection.
- No batteries to monitor or replace
- No Wi-Fi, Bluetooth, or mobile app required
- Convenient code entry for authorized users
- Physical key override on this installation
- Suitable for customers who prefer a mechanical access solution
Choosing Between Mechanical and Electronic Keyless Entry
Mechanical keyless locks are designed for straightforward code access without power. Electronic smart locks may offer features such as temporary codes, activity records, remote management, or integration with other systems, but they require compatible doors and ongoing power or battery management. The better option depends on who needs access, how often codes must change, and whether remote features are actually useful.
