Yaris 2007 remote entry doesn't open (it only closes)

[Revsson]

I would add that even though the LED lights, doesn't necessarily mean that the battery
is still good. As suggested, why not take it apart and clean it. Check the battery
voltage or even replace it. That way, you know you are probably starting with a like
new remote. CTScott can verify, but LEDs only need about 0.7v to light. I believe
the battery in the remote is a 3.0v. So, if it is indeed the original battery from 2007,
it might be time to change it anyway.

Thank you both for your replies

I'll try ASAP, but I don't think this could be a solution.
Button should be a single contact one, so if the LED lights up it means the contact is closed...
But maybe the button is a double contact, one for the power/LED and the other for the command; I'll check it this evening.

The remote surely has a single radio circuit that transmits two different codes on the same frequency, one for Lock and another for Unlock command.
Lock ALWAYS works, even far from the car, no one single command missed.
Unlock NEVER works, even near to the car.
That's why I excluded a battery issue.
Anyway it worths a try...
