Making a 12v garage opener for your bike

[sooprvylyn]

Hey all, just wanted to post how I made a 12v garage door opener for 2 different doors on the same button for my bike in case anyone wants to do it. I wanted a single button to open both my garage door and the community gate, which are different brands. Pretty easy but there are a couple things I learned along the way:

First thing you want to do is get some small garage door openers for any doors you need to open. Get the Keychain ones as they are small and can be combined into a single small housing/project box.  Get them programmed to your doors.

Next, pull them out of their housings and note the battery voltage. Some will be 12v already, but some may 3v or 6v and will need to have the 12v power reduced.

If you need to reduce the voltage you will need to buy a mini buck converter that will handle 12v input.  Get one like these:
EBOOT Mini MP1584EN DC-DC Buck Converter Adjustable Power Module 24V to 12V 9V 5V 3V (6) https://a.co/d/0bAnWVs

On the buck converter there are inputs and outputs. Wire the inputs with wires you can connect to a 12 power supply, your motorcycle battery is fine for this. Then wire the output wires in contact with a multimeter set to voltage. There is a small potentiometer dial on the buck converter that you will GENTLY, turn with a small Phillips head driver until the output reading on your multimeter reads the correct voltage for the garage door opener you want to use.  Once it's set you are ready to wire everything up.

BE CAREFUL CONNECTING THE BUCK CONVERTER TO THE CORRECT BATTERY TERMINALS. IF YOU SWITCH THEM YOULL FRY THE BUCK CONVERTER AND HAVE TO START OVER. AT LEAST THEY ARE CHEAP.

The first thing you want to do is remove the battery connectiors on your remotes. Note which pin is positive and which is negative.

Next, solder the terminals on the switch for your remotes together so that you are bypassing the switch.

After that you will solder the positive battery(or buck converter pos output if you are using one) to the positive pin/terminal on where the positive side of the battery connector was on your remote. Do the same for the negative side.

If you want to use multiple remotes on the same button, connect both/all of the positive remote inputs and do the same with the negatives.

Now all you have to do is wire in to a switch. Find a project box that will fit the remote circuitboard/s.

This will not work on a remote with multiple switches. You need a separate remote for each door you want to open on the same switch.

If you are only doing a single remote, you can connect your switch to the switch terminals on the remote and just connect the battery leads directly

Skylink 69P keychain remote that uses a 12V size 23A battery so no voltage conversion is required. That's what I use for my K garage door openers.

Yeah, there are definitely some remotes for some brands that use 12v batteries.  The one for my front gate used 12v.  I couldn't find a 12v one for my particular garage door to my house tho(post 2006 intellicode which uses a different frequency than this remote, in fact I think I even tried this one during my quest)....so a buck converter is the solution for such challenges.

Mostly just posting in case someone has similar needs as I did.
