I have "starting" problem with my 95 Ford Explorer 4x4.

I cannot close or open doors with my remote key. I can open the door with
key and tried to start  i press the button on my remote key, but it wont
work. The red light/key still blinks...

I have change the battery to remote key and all fuse are ok.

What i should do now ??
Is there any possible to disable this anti-theft ???

Regards Aki
