Mechanical Code Locks — No Battery, No Power, No App Required
Mechanical code locks provide reliable keyless access without any electronics, batteries or wiring. A push-button or dial code replaces the key — and because there are no moving electronic parts, there is nothing to go flat, fail or get hacked. Shop our range of mechanical digital locks from Borg and Carbine for gates, offices, storerooms, sheds, schools and any application where keyless access needs to just work — every time.
Free shipping Australia-wide on orders over $100. Pick up available from our four Melbourne stores in Frankston, Mornington, Rosebud and Braeside.
Why Choose a Mechanical Code Lock?
Mechanical code locks have one decisive advantage over battery-powered digital locks: they never go flat. For gates, external storerooms, sheds, plant rooms and any door that is not accessed daily, a mechanical lock is often the smarter choice. There is no battery maintenance schedule, no app to update, no connectivity to troubleshoot — just enter the code and the door opens.
They are also the preferred choice for high-traffic commercial applications where a battery-powered lock would need frequent replacement, and for marine and outdoor environments where electronics are vulnerable to corrosion. Borg's Marine Grade Pro series uses 316 stainless steel internal components specifically designed to resist salt water corrosion.
Mechanical Code Lock vs Battery-Powered Digital Lock

Mechanical code lock — no battery, no power, no app, no connectivity. Single or multiple access codes. Lower cost. Ideal for gates, sheds, storerooms, offices and any location where reliability matters more than remote control.
-
Battery-powered digital lock — PIN, fingerprint, RFID or Bluetooth access. App control available on smart models. Requires battery replacement every 8 to 12 months. Ideal for front doors, Airbnb properties and any application where remote access or audit trails are needed.

Frequently Asked Questions
What is a mechanical code lock?
A mechanical code lock is a keypad lock that operates entirely without electricity, batteries or wiring. A push-button code engages and disengages the latch or deadbolt through a purely mechanical mechanism. Nothing to go flat, nothing to update — just a code that opens the door.
How do I change the code on a mechanical code lock?
Most Borg mechanical locks use the ECP (Easi-Code Pro) system which allows the code to be changed directly on the door without removing the lock. The process involves a specific button sequence using the current code — full instructions are included with each lock. Some older mechanical locks require partial disassembly to change the code.
Are mechanical code locks secure?
Yes. Mechanical code locks provide strong protection against forced entry and eliminate the risks associated with key duplication. They cannot be hacked remotely and are not vulnerable to battery failure lockouts. Most Borg locks include a key override option for emergency access. For the highest security, choose a model with a clutch mechanism that prevents code deciphering from observing handle movement.
Can a mechanical code lock be used on a gate?
Yes. Borg manufactures a dedicated range of gate locks designed for metal and timber pedestrian gates. The marine-grade Pro series uses 316 stainless steel internal components for corrosion resistance in coastal environments. Gate lock models are available with single or dual keypads (back-to-back) and with or without key override.
How many codes can a mechanical code lock store?
Most mechanical code locks operate on a single code that can be changed as needed. Unlike battery-powered digital locks which can store dozens of individual user codes, mechanical locks provide one shared access code. This is appropriate for most gate and storeroom applications. If you need individual user codes or access logs, a battery-powered digital lock is more suitable.
Are mechanical code locks weatherproof?
Standard mechanical code locks are suitable for sheltered outdoor locations. For fully exposed outdoor use — particularly in coastal, marine or tropical environments — choose a lock specifically rated for outdoor exposure. Borg's Marine Grade Pro series is tested for salt water corrosion resistance and is the appropriate choice for gates and doors in coastal Australian locations.
