@hassam: liana comes with one key with remote and two keys with immobilizer chip only.
I have observed two things:
- remote does not work when a door is not properly closed
- remote does not work if a key is in the ignition
so enable the dome light to light on door open, close all doors and see if it illuminates still, that would mean one of the door closed sensors is bad, make sure you do not hear beeps if you open the driver's door while no key is inserted but you do when a key is in the ignition (car not started).
A replacement key is not going to be cheap
If you still have a problem feel free to call me at 03452129134.
