I had an interesting experience with my 2014’s key fob. The back half of case cracked and would not stay together / closed. Bought a pair on Amazon for $12 and swapped the internals but reused the original rubber button pad.

The functions began to be difficult to operate. First it would not lock or remote start, then it would not unlock. Tried a new battery with no improvement.

I checked out youtube on how to fix it. Two videos showed cleaning the circuit board button contacts with rubbing alcohol on a Q-tip as they get smudged with carbon from the conductive backs of the rubber buttons.

Simple fix so I tried it. Rubbed, rubbed and went through both ends of 4 Q-tips until the black carbon quit coming off on the Q-tips and now it works fine again.

Oops, correction, it stopped working again.

Changed rubber button pad and it started working for about ½ a day and quit again. Back to square one!

Check your solder joints where the battery contacts are. Mainly the negative. 1 or both sides will break or fatigue and will lose contact.
The button membranes are terrible on those.
Aftermarket remotes are really not any better, even right out of the package.
Have you replaced the battery?

Tried a new battery with no improvement.

I’ll check the solder joints.

Thanks

Battery clip solder joints were good.

Solved the problem. Seems when I replaced the cracked back cover, I re-used the original front cover with the new back cover and it went together alright, so I thought.

So, I tried the new front cover with its matching back cover, and it went together very tight, like the originals. Now everything works again. Just mis-matched covers made the difference in how the internal parts matched together.

ah yes. They are not compatible.
Believe it has to do with patents.
Look the same outside but very different internally
