So I took my car to the mechanic in order for him to fix a leak in a hose close to the alternator.

I went to pick up my car just before he close the workshop; when I turned the car on, I noticed it has the three amigos checks on the dashboard, it was the first time I saw this on my car, he told me to run the car so the checks will go off. Guess what? The checks kept there until I got home. Since I don't have scanner I unplugged the battery and plug it again after 5 minutes and the problems came on, I did that to get rid of the 3 amigos checks. And the car wasn't turning on after I plug back the battery, maybe any kind of security system?

Now the remote key isn't working either, like if I try to lock my car is not working, so I came with the stupid idea of closing the car manually by putting in the key in the driver's door lock and close it manually. Now I can lock and unlock the car manually but once I open any of the doors the alarm starts to sound.

TL;DR: After unplugging and plugging the battery the car won't start and it is not allowing me to open the doors remotely, only manually and alarm goes on because I tried to open and close the car with the key manually.

I tried this already -> and it is not working, I tried with default code 1515 and I don't have the EKA code with me. At the end it beeps once.

Something weird I just noticed is that if I open the back doors the alarm won't go on. It is only with the driver's door, if I open it the alarm goes on which is very annoying btw.

Do you guys have an idea on how I can fix this and why is this happening?

 

 

I had an unlock problem which I just locked and unlocked it a bunch of times and it fixed itself.
