GMC Universal Home Remote. Frequency?

[Industrial Toys]

I have one of those overhead console transmitters in my 08 Sierra.

I have used it sucessfully with my Chamberlain Jackshaft Opener.

It HAS provision for entering Dip switch Data for older openers.

I am trying to get it to work with a 318MHZ Receiver. 8 Dip switches, but without luck.

How does the Universal Remote know what frequency to transmit on? Will it do 318 MHZ? I have 8 Dip Switches, it accepts up to 12, do you need to enter 0s to make up the 12?

Thanks in Advance.

Not sure of frequency, but maybe this will help:

Thanks for that. Unfortunately, my console does not have the capability to listen to an existing transmitter and duplicate that signal. I'm surprised how little information is on the web. The 800 number for lear is no longer in service but directs yo to the web site learcar2u.com, but only comes up with the word "page" or something like that.

As usual, the instructions (from GM)are somewhat poor. I'm not complaining as I have tried many times to write technical instructions and it's very hard!

One part of if was cryptic and said to hold a button (to which you wish the function programmed) for up to 55 seconds, then release when the door works. I could not understand this. MAYBE, it's frequency hopping. That would make perfect sense for that unknown time parameter.

I had no luck programming the home link in my GM cars to my old garage door opener. Instead, I bought a cheap universal garage door opener from Lowes or Menards, hooked that to the garage door wires at the push button on the wall, and programmed that to my car. Works like a champ. Less than $25.00.

I hate being defeated. Was your opener a DIP switch programmed unit? What make?

As usual, this was supposed to be a small part of a larger project, and now I'm spending all this time on this little part.

It's actually funny, because apparently you need a (presumably cross band) repeater to operate the latest Chamberlain manufactured openers with that Universal Remote.

My garage door opener is a 30+ year old Sears unit with DIP switches. It's pre-rolling code. The three remotes we had were slowly failing, and, we wanted to be able to use the home link in the Impala.

I purchased a Chamberlain 955D universal remote control. It has a receiver and one remote control. Google "Chamberlain 955D" and you'll get plenty of hits and prices.

I removed the two wire garage door opener button on the wall in the garage and replaced it with the 955D receiver. Then I followed the home link instructions in the Impala's owner's manual, and the instructions that came with the 955D, and some on-line videos and was able to capture it with the buttons on the overhead console in the Impala.

As noted in the complaints in the reviews, the range is not that good. I connected a 20' piece of wire to the little wire antenna on the 955D and stapled it across the header of my garage door. Problem solved. About a 30' range in front of the closed door with the Impala.

We keep the remote that came with the 955D in the house by the back door and that works fine as well.

Hope that helps. It's a $30 test.

Thanks! What a difficult thing to research. Googling it gets you web sites of beautiful people, their beautiful children and their beautiful homes, and how this product can make you happier and safer, but no technical data.

I finally found a list for newer equipment that had thousands of listings. Everything from 27 MHZ to a Gig, but absolutely nothing in 318 MHZ. That tells me something.

So despite having brand new Linear Receivers, I wanted to use, I guess I will buy the mentioned receiver. At least I know that works.

EDIT: I think that 955D kit is a repeater. I need some dry contacts for a security application. Basically, a method of bypassing my various entrance security systems, on me entering.

Ours has been installed for about 3-4 years now. Still works. So I'm at about $8.75 per year. :laughing:

No luck at all. Now I tried a Visonic Receiver. Yet another great company, now destroyed by being bought out by Johnston controls. Typical. Long hold times, totally useless call center tech support (with no technical background, or historical product library) utilizing poor quality, low bandwidth IP voice lines. Does anything ever get better or is it all just entropy?

I probably could have gotten better information from my mother, and not spent as much time in doing so. Thanks Johnston Controls!

 

[MossRoad]

No luck with what?

 

[Industrial Toys]

With anything really. On the phone with Chamberlain. Try asking a call center rep what frequency a given opener uses?

There was a time when tech support may say, hey, yeah, I designed that thing. Now they just grab any dummy off the street that can read it seems.

 

[MossRoad]

Why do you need to know the frequency? :confused3:

To determine some starting point of compatibility. It's mind boggling. Lear, who made the GM console touts it as being able to control a myriad of devices, openers, gates, security, but can't for the life of them, give any idea as to what other devices their product has been known to work with specifically.

It's like so many things. The consumer is left to fend to his own devices. And Forums will always put Big Corporations to shame as far as providing any good information.

It's called the homelink. It works with most modern stuff. We use it on my in-laws 2008 Toyota Sienna at their house and our house, buttons 1 and 2 respectively. I use it at our house and their house with the same buttons in our Impala.

I don't think the Lear unit in my 08 is of that generation to support HomeLink. That being said. Three buttons doesn't give a whole lot of options.

ok. is that the lear car 2 U thing in the Sierra?

 

[MossRoad]

This should work. It's the same thing as the homelink unit I was showing you, but made for the Car2U.

This is likely what I need. Neither my 2011 GMC truck nor my wife's 2012 Chev Tahoe work with garage opener, Chamberlain told me I needed the Homelink repeater to convert to Security +2.0, but I bet now after reading the description that I need the Car2U repeater instead, not the Homelink repeater..

Description from link above..

One repeater can control multiple cars and openers; if all vehicles in the garage are HomeLinkｮ, only one HomeLinkｮ repeater is needed. If all vehicles are Car2U, only one Car2U repeater is needed. Both repeaters are required if different vehicles sharing the same garage have systems made by both interior suppliers. Consult your vehicle owners' manual if you are unsure of the system installed in your vehicle. HomeLinkｮ Repeater Kit HomeLinkｮ is available in many brands of vehicles, and is identified by a single red LED and 3 buttons; some models may have a "house" image on the panel. On mirror applications, the house may be absent but there is still just one LED. Most older vehicles and select newer models will need a repeater to upgrade the vehicle to be compatible with the new Security+ 2.0 radio code. Gentex Corporation has a website to determine vehicle compatibility; go to HomeLink and follow the steps to program a vehicle to see if you need the kit. Sample HomeLink in-vehicle system Sample HomeLink in-vehicle system Programming HomeLink-equipped Vehicles to Older LiftMasterｮ Garage Door Openers & Gate Operators To program older LiftMaster garage door openers (manufactured prior to 2011) to your HomeLink-equipped vehicle, visit HomeLink and follow the instructions. Car2U Vehicles Select 2007?013 GM & Ford vehicles may have Car2U remote systems manufactured by Lear Corporation, identified by three yellow LED lights, one above each button. The HomeLinkｮ repeater will not work with this system. A Car2U repeater purchased from Lear is required for all vehicles. Contact Lear at www.learcar2u.com or at (866) 572-2728.

Edit: yep, checked my vehicles, both have the 3 led/3 button setup, so I need the Car2U instead of the Homelink..
