This sounds like a logic board issue. Get a surge protector 900 joules or higher no matter what you do. You can find the web store in your manual for replacement parts. Thanks BB

Garage Door Remote Doesn't Work


Here’s a problem I’ve run into several times lately- the garage door opener remote no longer works. The good news is the solution has been very simple. Check your wall control.

Is the led solid or flashing? If it’s flashing you’re in luck. The wall control should have two buttons, one with a light symbol and one with a lock symbol. Press and hold the lock button for a few seconds then release. The led on the wall control should now be solid and your remotes will now function.

What’s that button for, you ask? Good question. It is a “vacation mode” setting so that when you’re gone the remote function is disabled decreasing the likelihood of break-in.

Most times no one pays much attention to the lock button; they are usually going for the light button and press lock by mistake.

Now if the wall control led was solid the whole time, this gets a little trickier. Grab a ladder and take a look at the side of the garage door opener where the wire hangs down, that’s the remote antenna. Near the antenna will be the “learn button” where you program the remotes. Right next to this button is an led. Now we can test the remote by pressing the button (on the remote not the learn button) and see if the led on the garage door opener lights up.

If the led lights up but there is no reaction from the opener it may be that the opener just needs to be reprogrammed. Sometimes the garage door opener gets a “brain freeze” and loses sync with the remote. Press the learn button and quickly release it, you now have 30 seconds to program your remote. Press and hold the remote button until you get a reaction from the opener, either the lights will flash or you will hear a click. Try your remote now to see if it works. If you are still having trouble the garage door opener’s logic board (where the learn button is located) may be faulty. This would be a very costly repair unless you are savvy enough to replace it yourself.)

If the led on the opener did not light up you may have a bad battery in the remote, the remote itself is bad or again the logic board is defective.

Try this method for programming. Press and hold the button down on the remote while you press and immediately release the learn button. Do this for each remote.

Have you replaced the battery in the keypad? Try this:

Locate the smart/learn button on the rear of the motor unit near where all those white wires go. Press and immediately release this and then walk over to the keypad and key in any 4 digit code you like and press enter.

Post back with your results.

Remote does not open garage door


It sounds like the wall button has the lock feature engauged.

Is there a small green LED flashing inside the wall button?
Push and hold the lock button for about two seconds and the LED should stop flashing. This will unlock the garage door opener and your remotes should start working. You may have to reprogram your remotes and homelink again since you triedprograming in the lock mode.

Good luck.

Programming the garage door opener


Homelink Garage Door Opener Programming Procedure:

The procedure described below was successfully applied to a 2005 Jaguar S-Type.

To begin with, several attempts were made using the programming instructions contained in my Jaguars owners manual. Though the procedure described in the owners manual was straight-forward and understandable, I was unsuccessful in getting the vehicles remote to make my garage door opener function. The particular garage door openers I have are both made by Genie. Both openers utilize the Rolling Code feature.

To begin with, be sure to clear previous codes on your Jaguars garage door opener by first turning (rotating) the ignition key to the I position (first notch). Next, simultaneously hold button 1 (left most button) and button 3 (right most button) down until the middle buttons red light changes from continuous on to a rapid flash. This process takes approximately 20-25 seconds. What follows is a two part process. In the first part, get your Genie portable remote and hold it near (approximately 3 inches away from) your Jaguars garage door opener console buttons. Choose which button on your Jaguars remote you wish to dedicate to your Genie door opener and simultaneously press and hold your Genie opener button and your Jaguars opener button. The red light on your Jaguars center button (button #2) will light up and within 1-2 seconds will begin to flash rapidly. You have just completed part 1 of the two part process.

Part two: Now it is time to utilize the Learn function on your Genie garage door opener. Press the Learn button on your Genie garage door opener. The red LED adjacent to the Learn button will begin to flash. You now have 30 seconds in which to program your Jaguars opener button. Using the same button you just used in the part 1 procedure, press and hold the same button for several seconds. As before, your Jaguars red light in the middle button will light up and within 1-2 seconds, it will flash rapidly. Release the button you are programming. Now, here is the key piece of information! Once again, press and hold that same button. Once again, the center buttons red light will flash rapidly. Release your newly programmed button. This procedure proved successful in my application. Here is what has just happened. The first time you pressed your Jaguars remote button tells the Genie opener that it exists and that it is a viable candidate for making your life easier (opening the damn door). The second time you press your Jaguars remote button confirms to the Genies rolling code that your Jaguars signal is legitimate and is to be trusted from then on.
