Sears Garage door opener + control outdoor lights

The TM751 uses 310MHz and (almost certainly) a different RF protocol than your Sears remote. They will not work together.

You may have confused the tech support people if you mentioned Homelink. Built-in Homelink transmitters can learn (both frequency and protocol) but your Sears remote cannot.

Are you sure about that? I thought that's basically the entire POINT of Homelink. It's a learning RF remote. If that's not the case, what the heck does Homelink do??? The Homelink buttons on my Prius rearview mirror do absolutely NOTHING until I train them on the RF remotes I want them to emulate.

My answer would have been that you need to

1) buy or borrow a palmpad RF remote, 2) set it and the wall switch to the code you want to use 3) make sure you can turn the lights on and off with the palmpad 4) train your garage door opener from the palmpad

Yes, I'm sure about that. I think you need to reread the original post. He does not have a Homelink equipped car but has a garage door remote which is sold as "Homelink compatible" which means that, if he did have a Homelink equipped car, he could use the garage door remote to train his Homelink. In this case, calling the remote "Homelink compatible" is about as meaningful as calling it "gravity compatible". I predict if you hold it at shoulder height and release your grip, it will demonstrate its "gravity compatibility".

The "compatibility" is in the Homelink system not in the garage door opener. Any ASK RF system using frequencies within the Homelink range is "Homelink compatible" in that the Homelink system can learn it. The garage door opener and remote use a fixed 315MHz frequency. The garage door opener can be trained to respond to two more of the remotes designed to work with it but cannot be trained for 310MHz or for the X-10 RF protocol.

Now, if you want to loan him your Prius... ;)

The 3-button garage door opener does not have any learning capability at all. The opener is homelink compatible which means that a "learning" home link transmitter (that also will work w/ rolling code) will open the door once it is programmed into the unit.

However there is a 2-button & a 4-button transmitter that one of the buttons does have the "learning" capability but they never automatically come w/ the units.

Can you get a handheld remote with full HomeLink learning capability?

Ah. I didn't think anyone would try to claim a non-learning, non-Homelink RF remote as being Homelink compatible. Yikes.

Actually, it is rather common to see "Homelink compatible" used this way.

I suspect Johnson Controls charges a hefty license fee for true "Homelink compatibility". Third-party remotes that use the Homelink technology sell for $150 (for a three button learning remote). I bet a big chunk of that is the license fee.

I see they can also learn FSK codes. The frequency (in the USA) extends from

288-418MHz with exclusions at 322-355MHz and 400-410MHz. They have a much broader frequency range in Europe.

From the Homelink website it's not clear whether they can learn a variety of rolling codes or only Keeloq codes. If the former, it raises fundamental questions about the security of rolling codes.

I just came across Chamberlain's "The Clicker® Universal Garage Door Opener Remote Control"...

This appears to be the learning remote alluded to by doordoc that is compatible with your opener. There's also a compatible lamp module.
