Here is a reminder of some important dates and information:
- 1993: in the US and Canada, the mandatory addition of a photoelectric safety reversing system for residential door openers, meaning door openers then had 2 safety systems, mechanical and photoelectric.
- Before 1993: remote transmitters were programmed using switches (+, 0, -)
- 1993 to 1995: remote transmitters were equipped with Billion code technology and the frequency used was 390 MHz (note: the 390 MHz frequency is used by American aircraft at certain military bases and could interfere with signals used for garage door openers)
- 1996 to 2005: LiftMaster equips it door openers with the Security+ system, using rolling code technology
- 2006 to 2012: Security+ with 315 MHz frequency
- 2013: the debut of MyQ technology from LiftMaster.
2017: beginning of August, LiftMaster door openers come equipped with MyQ technology and integrated Wi‑Fi. With the Wi‑Fi system, you can add peripheral devices like home lighting and interact with the biggest name in integrated home technologies like Apple HomeKit and Google Home.
Another way to check it out is from the "LEARN" button on the motor steel chassis. Take a step ladder and go check the colour of the Learn button. Remove the plastic cap that protects the lightbulb and see if the button is:
- Orange: then it’s a door opener made between 1996 and 2005, equipped with the Security+ system
- Purple: a door opener made between 2006 and 2014, equipped with the Security+ system
- After August 2012, the button is Yellow, and is equipped with the Security+ 2.0 system
- and since the middle of 2017, Wi‑Fi (the logo is seen on the motor chassis) has been integrated into door openers in addition to having the Security+ 2.0 system. This button is also Yellow.
Note that the dates mentioned about are approximate. There could be a difference of a few months and one year could be superimposed over another.
