My honda crv 2014 Key fob wont work on one of the keychains. The unlock button does nothing. When clicking Lock, it makes the red light led on for 5 secs, unlocks car and then nothing else. Not sure what is going on.

I tried reprogramming it and it worked for a couple of days, but then stopped again. I even checked for corrosion and it is all good.

 

Call pop a lock or tow it to the dealer to reprogram.
