Central locking and antitheft alarm

Hi.
I am relatively new to cars, driving and etc.
Recently I bought one Seat Ibiza 2003, and I have encountered some issues, some I resolved on myown, some I can't understand what it is 😁
Problem is when I lock the car with remote control locking, the red led on driver's door doesn't flash at all. It was strange to me, so I tried to stay in the car and activate alarm, but without luck.
Then I left windows open, so I could check doors, and actually, when I lock the car, I hear those two 'beeps' locking in, I tried to open doors from inside, and front passenger doors can open on second try (first unlock, second open). So only passenger doors. So I presume that's why alarm doesn't activate.
Does anyone know how to resolve this issue, and is this spare part I need expensive 😁
Thanks for this forum, it really helps with car ☺️
