    Ok so I am in Canada and I bought this used Craftsman remote keypad that you install on the side of your garage door on the outside of your house. I assumed that as long as the keypad brand was Craftsman, Liftmaster, Chamberlain or Wayne dalton, that any keypad of these brands would work with any of these brands of garage door openers. WRONG!! I spent $40.00 for a used keypad only to find out that it is not compatible. So to avoid you all from making the same is what I learned or know now. First off it is very important to try to find out what colour the square plastic learn button on the actual garage door motor was that the remote keypad you are looking to buy , was used with. It is also a good idea to find out what the FCC ID # is on the back of the remote keypad you are looking to buy.Once you have the FCC ID# for example mine was FCC ID# HBW1631. You can type into Google searchbox "FCC ID# Lookup" and that will take you to the FCC's website. If a search box does not automatically pop up, you scroll on the left side of the page and look for "FCC ID Search". A box pops up. The first box is called "Grantee Code (first 3 to 5 characters)...mine was HBW. The second box underneath is called "Product Code (remaining characters of the FCC ID#).......mine was 1631. Hit search and a result should pop up, In that result you see a lot of info but at the far right you will see the lower and upper frequency range of your remote keypad you are either selling or planning to buy. Mine was 315MHz upper and lower range. So that means that my remote keypad will only work with garage door motors that operate on or between a lower and upper range of frequencies that include 315MHz. Now we have to find out what frequency the garage door motor is. If you are buying the remote the seller what colour the Learn Button is on the garage door motor. For my remote keypad I bought, it worked with a Green or Purple Learn Button on the motor. So the keypad I bought would not work with my motor with a red learn button. To find out what frequency your garage door motor operates at, you can either call customer service for the brand you own and give them the model number.Or Google the model number to search what frequency the motor operates at. I had a hard time googling it so I just called Chamberlain customer service and they told me my motor is 390MHz. So now I know the frequency range my garage door motor operates within, I can look for used remote keypads, ask the seller what the FCC ID# is, then type it into the FCC ID Search Lookup website to see if the remote keypad frequency falls within the operating frequency range of the garage Door Motor. Hope that helps a bit guys and gals. Kev

I bought a new Chamberlain garage door remote control (Model 953EV/EVC) but my garage door opener is date 1991. Can I get this remote to sync with it? I have one remote dated 1993 that came with the...

The 953EV/EVC remote is designed to work with garage door openers at 315MHz (more or less). Your older unit doesn't work at that frequency. I'm not positive but it could be 300MHz.

You need a retrofit unit to use the new remote. See for one that works with Chamberlain units.

I hope this helps.

I have a Craftsman 41A315-7D garage door opener. I can program one or the other of the two remotes I own. Either one will work fine but I can not get both to work. Its one or the other... not both. The...

You can program more than one remote if they are the same model number and/or the same technology. If your remotes are the same model number then one has converted to an earlier technology. You will need to purchase a new remote and then you will find that the new one will work with one of the old remotes but not the other. Get rid of the bad remote to prevent complications in the future.

Cant get 2 remotes for garage door openers working at same time

You have a remote that has reverted to an earlier technology. The only way out of this is to purchase the same exact model number called for by your opener and go through the programming. You will find the new one will work with one of the old ones. Remove the battery from the one that isn't and drop it in the garbage.

2 different openers stopped working by remote at the same time

Both the older genie and a newer chamberlain (3-4 yrs old) both run on 390Mhz frequency. sounds like you will have to change your receivers on both operators (365LM 315Mhz) then get 3 button remote so you can program both doors on one remote.
