I have an ET 500 gate motor. My neighbour's remote opens my gate as well when she opens her garage door. How can I change my ET receiver to prevent the neighbour opening my ET gate motor?

There is a video for that remote at the web site above. Check it in case it helps.

LiftMaster 371LM Gate or Garage Door Opener Remote Transmitter 315 MHz...

receiver stand alone I doubt it

quicker to upgrade the whole lot
motor set up and receiver
most receiver and the remote today are generic
fit to all types of doors

You have a power leak in the remote; change it!

Check the antenna at the gate for corrosion at the connector and make sure it's not bent. Water can get in and make the connection intermittent. Also tighten the screws on the main control board where wires from the receiver connect.

Someone in your neighborhood may have the same garage door opener that you have and sharing the same code. Change your garage door opener code or buy a Genie Code Scrambler.

No. It's not possible. There is no setup codes to synchronize with.

My first inclination is that your keypad and remote have been removed from the Logic board memory.
If you have the Opener's instruction manual, then go to the programming section for how to re-program your keypad and remote.
If you do not have your manual then you can go to the Liftmaster website and download / view the manual for your particular unit. You will need the model number for your unit. That can be found near the light fixture on the unit (if you have two light fixtures, then look for a data sticker that indicates Model number and Serial number. You may have to remove or lift the light cover in order to find it.)

To answer your second question, I will need to know what model of gate opener you have, and also need to know if there is a separate Receiver box unit or not. Most Gate operators will have the receiver unit built into them. Some however do not, and an external one will be wired to the gate motor unit, and possibly mounted to a wall near the gate motor. question: do you use the same remote for the gate that you use for the Garage door opener or do you have a separate remote for each? If you do, I need the model number on the remote for the gate operator. That will tell me what kind of tx/rx you have and possibly where to locate the learn button.

It is very important to erase the memory of your unit and then reprogram your remotes. Erase the memory by holding the smart/learn button in for 6 seconds. None of your remotes or wireless keypad will work. Now program your remotes this way. Press and hold the button down on your remote and then press and immediately release the smart learn button.

If you have a wireless keypad program it like this. Press and immediately release the smart/learn button and then walk over to your keypad and key in your 4 digit code.

I would make sure your neighbor isn't using his opener when you are programming your keypad.
