Lockwood Cortex Digital Lockset - CTX3772 with 3772 Mortice Lock, 60mm Backset, Satin Chrome, Fire Rated, Key Override
The Lockwood Cortex CTX3772SC/3772 is a commercial grade standalone digital lockset combining a capacitive touchscreen keypad and integrated RFID card reader with the Lockwood 3772 mortice lock. It delivers PIN code and card-based electronic access control without requiring network infrastructure, wiring, or a power supply - operating entirely on four AA batteries.
The CTX3772 is the mid-range mortice variant in the Cortex range. It uses a 60mm backset 3772 mortice lock and includes a key override cylinder, providing mechanical backup access. It also enables two exclusive mortice-only features: Code Lockout (using the cylinder to electronically lock out all card and PIN users) and Latch Holdback (using the cylinder to hold the latch back for high-traffic periods). Both functions require the VCam accessory.
The Cortex is the first Australian digital lockset to be fire rated with Lockwood mortice variants. Free egress from the inside is always available regardless of access mode or programming state.

About the Lockwood 3772 Mortice Lock
The Lockwood Selector 3772 is a heavy-duty commercial cylinder mortice lock used across industrial, commercial, institutional, and hospitality applications. It uses a universal primary lock body with red/green function setting and all lock settings configurable from under the faceplate. It includes anti-lockout and holdback capabilities as standard, and is compatible with Lockwood 1800 and 2800 Series door furniture.
The 3772 is available in three backset sizes. The CTX3772SC/3772 Cortex lockset is supplied with the 60mm backset variant.
Bold row indicates the variant supplied with the CTX3772SC/3772 Cortex lockset. Door furniture (Lockwood 1800 or 2800 Series) must be ordered separately and is not included.

Suitable Uses
- Commercial office entry doors requiring standalone electronic access control with mechanical key backup
- Fire-rated door assemblies requiring a digital mortice lockset
- Doors where key override is required for building management, emergency services, or insurance compliance
- High-security applications requiring Dual Security Credential (card and PIN from two users)
- High-traffic doors where Latch Holdback is needed for set periods of the day
- Sites integrating with an existing iClass or Mifare card-based access system
- Applications requiring time-based access control without network infrastructure
- Doors requiring DDA-compliant lever hardware
Installation Tips
- A 28mm hole saw is required for door preparation. Use the supplied CTX3772 door preparation template to mark drilling positions accurately before cutting.
- Select the correct spindle length to suit the door thickness. See the spindle selection diagram below.
- The 3772 mortice lock is supplied separately and must be installed in the door edge before fitting the Cortex escutcheon panels.
- A 60mm latch is required. Confirm the door preparation and backset measurement before installation.
- For Code Lockout and Latch Holdback functions, the VCam accessory must be fitted under the mortice faceplate. These functions are not available without the VCam.
- Latch Holdback must not be activated on fire-rated doors as it prevents the door from self-closing and latching - a requirement of fire door assemblies.
- For fire door installations, confirm that the complete doorset assembly is part of a compliant fire-rated system.
Frequently Asked Questions
- What is the difference between the CTX3772 and the CTX530?
The CTX3772 uses a 3772 mortice lock and includes a key override cylinder, making it taller (278mm vs 215mm) and giving it two additional features: Code Lockout and Latch Holdback (both require the VCam accessory). The CTX3772 is fire rated like the CTX530, but provides more mechanical security and management capability through the mortice lock and cylinder. The CTX530 uses a simpler 530 tubular latch and has no key override. - What is the Code Lockout function?
Code Lockout allows an authorised person to use the key cylinder to electronically disable all card and PIN user access - locking out all electronic credentials while the mechanical key still works. This is useful for after-hours security or when the site needs to be placed in a restricted state. The VCam accessory must be installed under the mortice faceplate for this function to operate. - Can the Latch Holdback be used on a fire door?
No. Latch Holdback must not be activated on fire-rated doors. Fire doors are required to self-close and latch - holding the latch back prevents this and would compromise the fire rating of the doorset. The Cortex catalogue explicitly notes this restriction. - What happens if the batteries run flat?
The Cortex includes a Battery Emergency PINS function that allows entry when batteries are critically low. The Smart Battery Check function provides accurate battery level reporting and ignores false battery recovery readings. If all else fails, the key override cylinder provides mechanical access independent of battery state. - Can this lock work with our existing access cards?
The Cortex supports both iClass and Mifare card formats - covering approximately 90% of existing access control card systems used worldwide. If your site currently uses iClass or Mifare cards, those cards can be programmed into the Cortex with no effect on your existing system.
Additional Information
- Mortice Lock vs Tubular Latch:
The 3772 mortice lock provides a higher level of mechanical security than the 530 tubular latch. Mortice locks engage more deeply into the door frame and are more resistant to forced entry. The cylinder override and mortice body together make the CTX3772 better suited to external or higher-security door applications than the CTX530. - VCam Accessory:
The VCam is a small accessory fitted under the mortice faceplate that enables the Code Lockout and Latch Holdback cylinder-operated functions. It is not included in the box and must be purchased and installed separately if these functions are required. Without the VCam, the CTX3772 operates as a standard electronic lockset with key override only. - Capacitive Touchscreen Security:
The capacitive touch buttons have no moving parts and cannot wear to reveal a frequently entered PIN. The Cryptic Code function allows random digits to be entered before or after the real PIN without affecting authentication, preventing shoulder-surfing attacks. - Dual Security Credential Mode:
This mode requires two users to be simultaneously present - one presenting a card, the other entering a PIN. It is intended for high-security applications such as server rooms, pharmacies, or cash handling areas where a two-person rule is required. - Upgrade Path:
The CTX3772 can be upgraded to the DX3572 mechanical keypad system if electronic features are no longer required or if the site transitions away from electronic access control. - Australian Compliance:
The CTX3772 meets Australian Electrical Regulatory Compliance (RCM) and European Electric Compliance (CE). It is rated to Australian Lock Standard AS4145.2:1993 at Security Level SL8 and Durability Level DL8.
