Mitsubishi Lancer Ralliart 2006 Remotes FOB not working

Hi there I have a Mitsubishi Lancer Ralliart 2006 and my Remotes just stopped workings (Batteries are good).
No remote start, no lock-unlock, no alarm.

When I start the car the only button that show signs of life is Aux which you can only press one time (right after starting up car, On position wont work). The hazards are flashings and the doors lock-unlock once (I guess this is the programming mode).

The receiver behind my rear view mirror doesn't flash anymore (Usually Pulse Blue Light).
By the way I noticed that my horn would honk by itself sometimes while driving.

I'm not sure about the name of the system (Installed at the dealership in 2006 Quebec,Canada), But on the sticker you can read "P5U Rev 1.14A".

Fuse (15) is good.

Thanks for you help!
