Hello Everyone,

I have a 08 EX-L AT, and whenever I press the lock, unlock or trunk button, the little red LED on the fob blinks. But it doesn’t unlock the or lock the car everytime. Sometime, it takes two-three clicks. Sometimes, a dozen are not enough and I have to put the key into door to unlock/lock.
I believe that the battery in the fob is good, as the red LED blinks every time.

sometimes, it works so well that when I am pressing the lock button repeatedly, it works twice in a miracle, and the car horn honks to affirm that it is locked xD, but luck isn’t on my side everytime.
The door lock unlock button on the driver door work perfectly.
I have one key fob and one valet key.

kindly advise a possible fix to this solution, and a happy Christmas to everyone who reads this.

So you haven't tried a new battery yet

Try replacing the fob battery. The light may come on but the signal might be to weak for the car to read it.

Mine does this especially in the cold. I think the battery is a 2016 3V Battery.

EDIT: it's a CR1616 Battery.

Today I have replaced the battery but the problem persists. Any other leads?

Wonder if your FOB is just wore out. Buttons wore out?

Wonder if your FOB is just wore out. Buttons wore out?

but if the buttons are worn out, the led on the fob must not work every time.

is there something that can be checked, in the vehicle, like a signal receiving antena or a joint, a plug, a quick fix, etc?

The fab might not be paired with the car anymore possibly? I know when you get new keys or fabs you have to pair it through a locking and unlocking sequence (At least for my Silverado I did) so you may have to re-pair it to the car.

Or the receiver of the fab's signal is blocked by something/has a loose connection

My understanding is that the driver’s window switch has the sensor for the door locks and is known to go out. I haven’t tried to replace mine yet but a friend at the dealer told me this is most likely the culprit.
