Hi, my name is*****'m a little confused as to the problem. What do you mean when you say "the remote key work good"? Do you mean that the remote works to unlock the doors?

Hi Marty I mean the remote work but the car doesn't unlock
Expert:  Marty replied 10 months ago.

I'm still not following you. If the car doesn't unlock how do you know that the remote is working?

Customer: replied 10 months ago.
the red light on remote is flashing when i hit the unlock or lock button
Expert:  Marty replied 10 months ago.

Are you able to open the car with the mechanical key? If so, does the car start?

Customer: replied 10 months ago.
I tried with the mechanical key it doesn't work the car still lock

It sounds like your car battery is dead. You need to rotate the lock counterclockwise and hold it there then pull on the door handle. Did you do that? I've attached a picture below. It helps if you slide the key into the end of the fob abd use the fob to turn the key.
