Remote alarm not working

[kropekoi]

Hi guys!

I need your help, we have a Yaris Sedan and at first the remote of the alarm was working and even if you are a few feet away, you can just press the lock from the remote and the car will get locked. However, the longer it gets the more weaker it is. I have to get near the car for the alarm to work and to get the car lock and unlocked. We have 2 remote for the alarm, and now only 1 works. A few days ago it was working and now, its not. The 2 remotes are not working, you can see its blinking on the remote when you press on it, but the car is not even recognizing that you are pressing on it, nothing happens. Now I have to manually insert the key to have the car locked, and unlocked.


Any help is highly appreciated!


The name of the alarm is Alien.
