I think I understand the problem, as it appears a lot of other people are asking the same question all over the internet and this site, too. Answered it elsewhere, but will answer here too:
I recently bought a Klic2 from Clicker Products After MUCH research and trying ALL the codes in their instruction manual, (because I was convinced I would succeed somehow - they said so...) it turns out that the Lynx Pro 455 (Model 2211L) operates on a frequency of 303 Mhz. All the other garage door openers operate at different frequencies: the so-called generics at something like 390MHz or 315MHz... or something like that, anyways.
The bottom line is that the Home Depot products currently being sold as "compatible with EVERY Garage Door Opener" (as clearly stated on the actual package) are NOT compatible with Lynx. In case you are interested, the Lynx garage door opener comes from Lynx products which originates out of New South Wales, but has mfg and distribution in North America. Their very meager and virtually useless emailed the company for a user manual (which is NOT available for download on the website) earlier today. We'll see if they respond. Totally frustrating.
Last little bit if you are interested: The only compatible keypad that I've been able to find is one which is proprietary to the manufacturer, and called "lynx PROLINE KEYPAD". The only place that I've been able to find selling this item is DEK Canada Strangely enough, I can't find any place that actually sells the Lynx Garage Door Openers brand new? Anyone have any idea if these are actually retailed to consumers? This unit came installed in a new construction project - so perhaps the builder got a deal. I can't find Lynx at Home Depot, Rona, CDN Tire or elsewhere...
