Replacing a garage remote?

cirx08

Hi, I've had these remotes for a very long time, about 15-20 years and all 4 that I have are now broken. Does anyone know what kind of remote they are so I can get new ones?

They are the type that you program by moving the 8 switches to match the pattern of the switches in the receiver as shown in the picture but I have no idea what these types of remotes are called?

P.S. The shop they were bought at is long gone so I can't go back there for a replacement.

That is a relatively simple circuit and should be easily repairable.

The chip shown is a remote control encoder and there is very little else there, so replacing it, or repairing a track might be all that is needed.
It might only be a failed diode that is the problem.

To be honest I'd rather just replace the whole remotes because it's not just the circuit boards that are broken, the cases that hold them have also been broken over the years, some now missing buttons and others that don't stay closed.
