Programming remote without instructions

If you have a multi-code opener, garage door opener won’t work unless it’s trained with a remote that has a matching code. What you can do is open a garage door manually from inside the garage. Then use the same button on your old or spare remote to open it from outside while standing close enough so that both buttons activate one garage door opener at once. After it opens, close the door using your wall switch or by pressing on/off button on new remote twice in quick succession (i.e., and release first then immediately press and hold it again). That will set up a matching code to be used for this opener.

Programming remote using manual

If you don’t have a spare remote and your remotes look different from each other (i.e., one has display and buttons that light up, another is simpler), then the only way out might be programming via switch inside the garage door opener itself. When you press one of those small buttons located on logic board, it tells the opener which position the switch is in. So if you press button 1 and it activates switch 1 (which is closed), then make sure that 2 and 3 switches are open (not closed). Then repeat with button number 2 etc. until all switches are activated by your remote buttons. That should set up matching code to be used for this opener.

Changing the battery of remote

Please note that remote batteries must be replaced from time to time, especially if it is a key fob with a battery built into the back side of it (see picture). If the key doesn’t have a light on it when you press a button, then maybe the battery is dead and needs replacement or there’s no power going to the receiver at all.

In that case first check whether there’s power going to garage door opener itself by plugging in an ordinary bulb into wall outlet controlled by switch inside your garage and pressing any button on your logic board, if bulb goes off or doesn’t turn on, then there’s no power coming from outside so something is wrong with the wiring and you need a help of a garage door repair company. Also, check all connections and switches on logic board as well as those located on wall button and keyless entry pad too.

Problem in logic board

If your opener is not communicating with remotes or even if it’s communicating but won’t open or close doors (e.g., lights on keypad are flashing), then there’s most likely something wrong with logic board (outdated boards can be repaired sometimes; otherwise they need to be replaced). If that doesn’t work, then maybe it’s time for new remote controls themselves most likely their batteries died and replacing them didn’t help because there was some other problem with the unit.

Note: Some remotes have battery backup so they can keep working when there’s no power going to opener (e.g., power outage) and thus don’t have to be programmed again after some time when the battery runs out of juice.

How to open older car garage doors with a remote control?

Check remote battery. If your remote control or keyless entry pad is not working, try replacing the batteries first. Make sure that you replace both batteries at the same time with new ones of the same brand and strength (i.e., alkaline). Don’t attempt to recharge regular alkaline batteries it will ruin them! You can buy rechargeable nickel-cadmium (NiCd) or nickel metal hydride (NiMh) batteries they are charged by plugging in a recharger into wall outlet (see your owner manual how to do it; takes about an hour), but those types of batteries lose their charge relatively fast, so you can’t leave them in your remote for a long time as it will be ruined as well.

Make sure opener is receiving signal from your remote

Pick up your remote control and press any button – if nothing happens, then probably opener won’t go either (most modern openers have security-rearming feature that prevents opening or closing doors when there’s no signal coming from outside). If you hear humming sound of gears moving but door doesn’t go up or down, check whether yellow indicator light on logic board blinks once for each press of a button by your remote.

If it doesn’t blink, try replacing the battery in keyless entry pad or receiver located inside the garage door opener motor head (you can use flashlight and magnifying glass to see what’s inside). Otherwise, if your opener doesn’t blink when you press buttons and yellow indicator light is not on at all or there’s just green LED lit next to it (indicating that logic board isn’t receiving any signals), then most likely something wrong with the receiver itself. If you have a multi-code garage door opener, most likely it needs service. These types of openers are less popular nowadays because other types are much more reliable.

Make sure remote works properly by using different one if possible

If replacing batteries didn’t help or you don’t have extra set of new batteries, try testing this remote control on another machine by pressing each button in order one after another. If you have a number of remote controls that work properly, then try using one from a different machine and see if your problem is gone.

Clean battery contacts and check for loose wires

If replacing batteries didn’t help or you don’t have extra set of batteries at the moment, clean the metal contacts on each device by wiping them with damp paper towel or cloth (you can use mild dish soap, just make sure nothing gets into an electric compartment covering it up). Also, inspect wiring connecting opener to wall switch and all wire connectors inside opener head every once in a while. If there’s some looseness that causes interruptions in signal transmission, tighten wires or replace faulty parts as needed (be extra-careful when working with electricity).

Replace opener motor head

If logic board works fine, but opener still doesn’t work properly even after replacing batteries, you might need to replace the opener motor head, it’s the most expensive part of a garage door opener system, so you should try all other options before that one.

If your garage is wired properly and main switch is on but there’s no power going to garage door opener motor, be sure to check black “hot” wire inside electric box behind opener for breaks or loose connections, this wire brings power from the furnace panel to your openers. If everything looks fine with wiring, then replace opener motor head by yourself if possible or contact a professional if not (opening garage doors is dangerous, so make sure to do it with caution).

Try replacing wireless keypad or cutting power to opener when not in use

Most garage door openers have a built-in battery that provides electricity to memory chips and logic board for about 30 seconds after being disconnected from the wall switch, this is a security feature preventing your opener from being operated by strangers if you accidentally opened the door while leaving it unattended. However, sometimes the batteries of wireless keypads can get weak resulting in signals not being sent properly at times try replacing the battery inside each remote control receiver.
