FORGE CB3 Smart Cabinet and Drawer Lock - Keypad, RFID Card, TTLock
At A Glance
(G5 Gateway)
The FORGE CB3 Smart Cabinet Lock (FECB03) puts a small round keypad - 51 mm across, with a built-in card reader - on the outside of a timber cabinet door or drawer front, through a single 20 mm hole. The lock body and batteries stay out of sight inside. It opens with a PIN code (up to 250), a MIFARE M1 card (up to 1,000) or the TTLock app over Bluetooth, with FORGE's optional G5 gateway for remote access. It suits timber 9-22 mm thick.
Like the CB1 it works in Private Mode or in Public (locker) Mode, where each user locks a cabinet with a one-time code or card of their own, and it installs vertically or horizontally, so it suits drawers as well as doors. Choose the version from the options on this page: FECB03TB with the spring-loaded latch receiver (door pusher) for cabinet doors, or FECB03TBDR with the fixed latch receiver for drawers and cabinets.
It runs on 3 x AA batteries for about 15 months, with a USB-C emergency power port on the keypad. For a lock with nothing on show, see the hidden FORGE CB2. Made in China for FORGE, an Australian brand based in Ringwood, Victoria, with FORGE's 2-year warranty.
Usually ships in 24 hours.
Owned by FORGE Electrical (Australia) · Manufactured in China. Our independent FORGE brand profile sets out how the range compares with the other brands we stock.
Access Methods
One administrator manages the lock in TTLock. Which users can open it depends on the mode - see Private Mode and Public Mode below.


TTLock App
Set the lock up in the free TTLock app, available for iOS and Android ![]()
. Choose Australia as your location when you sign up, give the app full permissions and turn Bluetooth on (manual page 14). Activate the lock first by pressing the reset button with a pin until it beeps twice - it then opens with the default passcode 123456# - and set the mode before adding it in the app (manual page 13). FORGE's TTLock pairing guide shows the general steps.
TTLock is one of the two global smart lock platforms - how it compares with Tuya is set out in our TTLock vs Tuya comparison, and the wider TTLock range in Chapter 14 - the TTLock hardware ecosystem. The app itself is covered in the TTLock app user manual.
Without a gateway the CB3 is managed over Bluetooth when your phone is within about 5-10 metres - see what a TTLock lock can do without Wi-Fi. FORGE offers the FORGE TTLock G5 gateway as the add-on for remote management: with it plugged in within range you can unlock remotely, send and change codes, manage cards and check entry records from anywhere - Bluetooth vs gateway in Chapter 14. Remote Unlock has to be switched on for the lock in the app (manual page 22).

Private Mode and Public Mode
The CB3 is set to one of two modes when it is installed, by entering a short code on the keypad before the lock is added to the app (manual page 15).
A user stores their things, closes the door and holds it shut, then enters a 4-10 digit code of their choosing followed by # - or presents an M1 card - to lock the cabinet. The same code or card opens it again, and the cabinet then resets for the next user (manual page 17). On the door-pusher version, a vacant cabinet is held slightly open by the receiver, so it is easy to see which ones are free. Suits gym and change-room lockers, hot desks and shared staff storage.
Key Features
- Cabinet and drawer lock with a round 51 mm keypad and card reader outside, through one 20 mm hole; lock body and batteries inside.
- PIN code (up to 250), MIFARE M1 card (up to 1,000) and the TTLock app over Bluetooth; one administrator.
- Private Mode (locked by default) or Public Mode - locker use, with a one-time code or card per user.
- Timber doors and drawer fronts 9-22 mm thick; vertical or horizontal installation; single or double-opening doors - door stopper plate included.
- Two versions: FECB03TB with a spring-loaded latch receiver that pushes the door open when it unlocks, or FECB03TBDR with a fixed latch receiver for drawers and cabinets.
- FORGE's optional G5 gateway for remote unlock, remote codes and cards, and entry records.
- 3 x AA batteries, about 10,000 unlocks or 15 months; low-battery warning; USB-C emergency power.
- Aluminium alloy; after five wrong attempts in a row the keypad locks for 90 seconds.

Will It Fit? Door Thickness, Receiver and Cut-out
The CB3 suits timber doors and drawer fronts 9-22 mm thick. The keypad mounts on the outside on its bracket and joins the lock body inside through one 20 mm hole (manual page 8). Where the hole goes depends on the version:
Positions from FORGE's CB3 manual and its two installation measurement guides.
- Door gap (A) - on a cabinet door, the gap between the cabinet side and the door edge; on a drawer, the gap between the rail above and the top of the drawer front. With a 2 mm gap the hole sits 48 mm (door pusher) or 44 mm (fixed receiver) in.
- Door thickness - 9 to 22 mm, timber.
- Receiver depth - set the spring-loaded receiver back from the frame's front edge by the door thickness plus 2 mm, and the fixed receiver by the door thickness (manual page 11; manual page 12).
- Room inside - the lock body is 122.8 x 65 mm and 22.8 mm deep, with the latch projecting 12 mm. On a drawer the keypad can stay upright while the body sits horizontally.
- Not sure? Send us a photo of the cabinet or drawer edge with a tape measure across the gap.

Available Finish Options
Black, silver keypad rim
(This Product)
STK FECB03TB / STK FECB03TBDR
Black keypad face and lock body with a silver rim around the keypad, as FORGE pictures it - choose the door-pusher (FECB03TB) or fixed-receiver (FECB03TBDR) version from the options on this page.
FORGE Smart Cabinet Locks
This product is in bold. All three run on TTLock over Bluetooth with the optional G5 gateway for remote access, and each is sold in two versions: TB with the spring-loaded latch receiver (door pusher) and TBDR with the fixed latch receiver. No IP rating - indoor cabinets and drawers.
Accessories and Spares
Other gateways are in the modules and Wi-Fi gateways category, and more cards and fobs in the RFID credentials range.
Battery and Emergency Power
The CB3 runs on 3 x AA alkaline batteries in the lock body, rated by FORGE at about 10,000 unlocks or around 15 months. The lock warns you when about 50 to 100 unlocks remain - replace all three then. If the batteries go flat, power the keypad from its USB-C emergency port with a USB A-to-C cable and a power bank, open the cabinet and fit new cells - FORGE notes that a C-to-C cable may supply no power (manual page 24). There is no key override, so keep a power bank and an A-to-C cable where you can find them. More on what really affects battery life and power and battery FAQs.
Weather and Environment - Indoor Cabinets
FORGE gives no IP rating for the CB3 - it is made for indoor timber cabinets and drawers, with a working range of -20 to 60 degrees C and 20-90% humidity. Keep it away from wet areas and outdoor storage.
FORGE CB3 - Technical Specifications
Dimensions
The cut-out positions for each receiver are in Will It Fit? above, and the receiver drawing is also in the Dimensions tab.
Platform and Data
Platform. The CB3 runs on TTLock - Bluetooth to your phone, with the TTLock G5 gateway for remote access. Remote unlock and management need the gateway; at the cabinet the lock works without the internet.
Where your data goes. TTLock is run by Sciener, a Chinese company. Accounts outside China use TTLock's out-of-China servers; where that infrastructure is hosted, and which region Australian accounts use, is not published - in short, a Chinese company's servers, location unpublished. For the platform-by-platform picture see where each smart lock platform hosts its data, and for TTLock's security record see Chapter 14 - TTLock security.
Installation
Fitting takes one 20 mm hole: the keypad goes on the outside on its bracket, the lock body inside, then the latch receiver on the cabinet or the rail above the drawer. The installation section of the manual covers cabinet doors and drawers with drawings.
- Measure the gap (A) and mark the hole centreline at 50 - A mm from the cabinet side for a cabinet door, or 46 - A mm below the top edge for a drawer front - FORGE's cabinet door and drawer guides show it.
- Drill the single 20 mm hole (manual page 8).
- Connect the data cable, fix the keypad with its bracket and the two M3 x 16 mm screws, then fit 3 x AA batteries and the battery cover. On a drawer the keypad can stay upright while the lock body sits horizontally (manual page 10).
- Fit the receiver - the spring-loaded one back from the frame's front edge by the door thickness plus 2 mm, the fixed one by the door thickness (manual page 11; manual page 12).
- Activate it by pressing the reset button with a pin until it beeps twice; it then opens with 123456#. The latch stays retracted until the lock is configured or a Public Mode code is set (manual page 13).
- Set the mode - *41#123456#2# for Private or *41#123456#1# for Public - then add the lock in TTLock (manual page 16). Terry's offers installation across the Gold Coast.
Cabinet and drawer gaps vary, so measure A on your own furniture. Photos that help us check a fit are in examples of helpful photos.
Frequently Asked Questions
The FECB03TB, with the spring-loaded receiver, for a cabinet door - it pushes the door open when it unlocks. The FECB03TBDR, with the fixed receiver, for drawers (and cabinets with their own handle).
Locker use. Vacant cabinets stay unlocked; a user locks one with a 4-10 digit code of their choosing or an M1 card, and opens it again with the same code or card, which then expires. The administrator can open any cabinet.
Yes - FORGE lists vertical or horizontal installation, and the FECB03TBDR's fixed receiver is made for drawers. The round keypad can stay upright while the lock body sits horizontally.

Power the keypad from the USB-C port with a USB A-to-C cable and a power bank, open the cabinet and fit 3 new AA cells. There is no key override.
Additional Information
- Choose the receiver first. Cabinet doors with the door pusher (FECB03TB) and drawers with the fixed receiver (FECB03TBDR) drill to different positions - 50 - A against 46 - A mm.
- Measure the gap before drilling. A 1 mm error in A moves the hole by 1 mm.
- Set the mode before handing it over. Until it is set up, the lock opens with the default passcode 123456#.
- Keep a power bank and a USB A-to-C cable handy - there is no key, and FORGE warns a C-to-C cable may not supply power.
- Check the door thickness. The CB3 is rated for 9-22 mm timber.
Warranty
2-year FORGE warranty from the date of delivery - covers defects in materials and workmanship under normal use.

FORGE CB3 Smart Cabinet Lock - FAQ, Setup and Owner's Guide
Everything below is here to help you choose, fit, set up and live with the FORGE CB3. For general smart lock questions see our Smart Lock FAQ (Chapter 13), and for measuring and fitting the Buyer's Guide.
Choosing and Fitting
Only the latch receiver. The FECB03TB's spring-loaded receiver pushes a cabinet door open when the lock releases; the FECB03TBDR's fixed receiver suits drawers and cabinets you pull open by a handle.
9 to 22 mm, timber (manual page 2).
Measure the gap A. On a cabinet door the 20 mm hole centreline sits 50 - A mm from the cabinet side; on a drawer, 46 - A mm below the top edge of the front (manual page 8; manual page 9).
Yes - vertical or horizontal. On a drawer the keypad can stay upright while the lock body sits horizontally (manual page 10).
Modes and Access
After activating the lock, wake the keypad and enter *41#123456#2# for Private Mode or *41#123456#1# for Public Mode, then add the lock in TTLock as the administrator (manual page 18; manual page 16).
Close the door and hold it shut, then enter a 4-10 digit code followed by # or present an M1 card. The same code or card unlocks it once, then the cabinet is free for the next user (manual page 17).
Time-limited, one-time (used within 6 hours of creation), permanent and recurring (manual page 19; Chapter 14 - passcode types).
MIFARE M1 cards - up to 1,000. One is in the box; extra FORGE MIFARE 1K cards are sold separately (manual page 20).
An eKey gives another TTLock account the right to unlock - time-limited, one-time, permanent or recurring - with options for remote unlock, an unlock link that works without the app, or near-administrator rights (manual page 21; TTLock eKeys).
After five wrong attempts in a row the lock ignores all input for 90 seconds. The keypad goes back to sleep after 20 seconds without use.
Remote Access and the G5 Gateway
Only for remote use. Codes and cards work with no phone at all, and the app works over Bluetooth within about 5-10 metres. Add the FORGE TTLock G5 gateway to unlock, issue access or check records from away from the cabinet - what a gateway actually does and the G5 explained.
Plug it in indoors within Bluetooth range of the CB3, on a 2.4 or 5 GHz Wi-Fi network - the closer the better, with as few walls and cabinet panels in between as possible (gateway placement).
Remote Unlock must be switched on for the lock in the app (manual page 22). Check that the gateway shows the lock in range.
Power and Batteries
About 10,000 unlocks or 15 months on 3 x AA alkaline cells, depending on use. The lock warns you when about 50 to 100 unlocks remain.
Connect a power bank to the USB-C port on the keypad with a USB A-to-C cable, open the cabinet with a code, card or the app, and replace the batteries. A C-to-C cable may supply no power (manual page 24).
Installation and Troubleshooting
Press the reset button with a pin until the lock beeps twice. It returns to its initial state and opens with 123456# (manual page 23).
A valid code or card retracts the latch for three seconds. On the FECB03TB, check the spring-loaded receiver is set back by the door thickness plus 2 mm so its pin can push the door; the fixed receiver has no pusher.
