Creasol UniLock: universal multi-frequency door opener (electric lock activator)

Creasol UniLock: universal multi-frequency door opener (electric lock activator)

SKU : creUniLock


This very small device, only 29x29x10mm, can be used with almost any radio remote controls in the market which transmit in a frequency between 288 MHz and 868 MHz, AM and FM, fixed and rolling code.

Also, it can receive in one or two different frequencies, even with different modulation.

When a known code is transmitted by the remote control, Creasol UniLock shorts the supply wires, simulating a pushbutton: in this way it permits to open an electric lock or electric strike plate by using any existing remote control in the market that was programmed on this receiver.

It can be used with electric lock supplied at 9÷18Vac or 9÷24Vdc, with current from 0.8 to 3.2A.

It's very easy to be installed: only two wires that should be connected in parallel to the pushbutton switch used to activate the electric lock.

No need for external supply or battery!

Fully configurable by the user: the operating frequency, shown in the table, can be simply programmed using the Prog button, as like as the number of activating pulses (1, 2, 3, 4) and their duration (100ms, 200ms, 400ms, 800ms).

In the same door opener it's possible to learn up to 60 different remote controls, even if different brand/model, both fixed and rolling code, AM and FM: the number of remote controls depends by the code complex, so, for example, it's possible to manage 60 12bit remote controls or 40 KeeLoq rolling code remote controls.

Creasol UniLock can be used to:

  • open the main entrance door by one or more existing remote controls (no need to purchase specific remote controls)
  • open the pedestrian gate/door
  • open any system which uses an electric lock

Using your existing remote control, it's possible for example to:

  1. open your garage door, using the existing electronic board and receiver;
  2. open your gate which uses a different frequency or codings, just installing a Creasol UniRec1 or Creasol UniRec2 receiver connected to it;
  3. open your pedestrian gate, installing a Creasol UniLock device;
  4. open your entrance door, installing a Creasol UniLock device.

So, with your existing remote control you can easely automate your house. Also, you can extend the number of remote controls using our Creasol Four and Creasol Multi remote control duplicators.

The product is made in Europe, provided in a nice transparent resealable recyclable clamshell, with instructions printed in several languages.

  • Very compact size: 29x29x10mm.

  • Works with an electric lock supplied  from 9 to 24Vdc and from 9 to 18Vac, with current from 0.8A to 3.2A

  • Frequency selected by the user: 433.42, 433.92, 434.15, 434.42, 868.3, 868.5, 868.8, 315*, 288*, 300*, 303*, 306*, 310*, 318*, 330*, 390*, 403.55*, 418* MHz. Frequencies marked with * cannot be used inside EU. The frequency of the remote control must be stable, so it does not work with remote controls without crystal or saw resonator (some bad remote controls operating around 300 MHz)!

  • OOK (AM) and FSK (FM) modulation is supported: FM with 2 different deviation value, 12,5 and 25 KHz; AM with standard and narrow bandwidth (higher sensitivity)

  • Twin frequency receiver: the user can select one or two frequencies/modulations as preferred, so it can receive, for example, at one single frequency or both 433 MHz OOK and 868 MHz FSK, or both 868MHz OOK and 315MHz OOK, or any combination of frequencies.

  • Works with a wide range of remote controls which transmit fixed or rolling code. See the compatibility table.

  • Manages different types of remote controls in the same time.

  • It's possible to learn one or more "master remote controls" that can be use just to enable learning for 10s without the need to access the receiver to press the Prog button.


Installing instructions


This device has 3 wires, one of which is used as antenna and should not be connected anywhere. Two wires should be connected to the existing switch, so a little current (20mA) will pass through the electric lock supplying Creasol UniLock. 

  1. Check the voltage on the existing switch: it should be in the range 9÷24Vdc or 9÷18Vac.

  2. Measure the current through the existing switch: it should be in the range 0.8÷3.2A

  3. Connect the 2 wires marked as Supply in parallel to the existing switch.

  4. Configure the frequency you wish to use, pressing Prog button for 5 times: LED shows the current programmed frequency, for example it flashes twice to indicate 433.92 MHz. Then press again Prog button N times, as indicated in the frequency table (for example 3 times for 868.3 MHz).
  5. Configure the number of pulses, pressing Prog button 6 times: LED flashes to indicate the current configuration. Press Prog button again to set the desired number.
  6. Configure the pulse length, pressing Prog button 7 times: LED flashes to indicate the current configuration. Press Prog button again to set the desired length.

Learning remote controls

Press the Prog button twice to enable learning mode: then it's possible to press a button on the existing remote control, within 10s, to learn it. Every time a new code is learned, the 10s timeout is reload.

LED flashes 2 times if the remote control has been learned, 3 times if it was already learned, 6 times if memory is full.

Removing remote controls

Press the Prog button 3 times, then it's possible to transmit, within 10s, from the remote control that need to be removed: LED flashes 4 times indicating that the remote control has been removed.

Alternatively, to blank memory (remove all remote controls), press Prog button for 10 times, LED flashes 10 times, then press again Prog button 3 times.

Learning "master" remote controls

Press the Prog button 4 times and follow the same procedure to learn remote controls: in this case it's possible to learn one or more "master" remote control, which can be used only to enable the learning procedure remotely, without the need to press the Prog button. Note that "master" remote controls do NOT activate the door opener output.

To learn new remote controls in this way, put the "master" remote control in trasmission for 1-2 seconds, then start to transmit for 1-2 seconds from the new remote controls: every time a new remote control is learned, the 10s timer is reload to permit successive learnings.



Application note: How to automate, in less than 10 minutes, a main door and/or a pedestrian gate using Creasol UniLock

The following schema shows how to connect the receiver Creasol UniLock to activate one or two electric locks.

In this way it's possible to easily open any pedestrian gate and/or the entrance door using almost any remote control in the market, because creUniLock is compatible almost any remote control, fixed and rolling code, AM and FM, working in the frequencies 433.42, 433.92, 434.15, 434.42 MHz, 868.3, 868.5, 868.8 MHz, 288, 300, 303, 306, 310, 315, 318, 330, 390, 403.55, 418MHz.

This cheap solution is also very simple to be integrated in the house, thanks to the easy connection and the very compact dimensions.

Creasol UniLock has only 3 wires: 1 as antenna that must be left open, and 2 wires that should be connected in parallel with the existing switch.
No need for additional power supply or battery!

When a valid code is transmitted by the remote control, the two wires will be internally shorted by the Creasol UniLock, letting the current (max 3.2A) flows through the electric lock, activating it.

Through the Prog button, the user can program the frequency, modulation (AM or FM), the number of activating pulses (1, 2, 3 or 4) and the pulse duration (100, 200, 400, 800ms).
