I had to change the batteries in the key fob but the light does not come on at each press as it used to. does this fob also need to be reset?
The immobilizer systems on these vehicles can only be accessed and programmed by a dealer or a shop with a T4 or Autologic scantool system. Typically, replacing batteries in a fob should not present any new issues. Try manually locking the vehicle with the key. One turn to the right with the key in the driver door should lock the whole vehicle, activate the alarm which is indicated by one horn beep, a flash of the parking lights & a rapid flashing of the red light on the dash. After less than a minute, the red light should go to a slower flash and the vehicle is now armed. By placing the key back in the drivers door, one turn to the left should de-activate the alarm and a second turn should un-lock the rest of the vehicle and it should start. If this does not work then the key may not be communicating with the vehicle and may need to be re-programmed. Make sure the batteries in the fob are correct, installed correctly and of good quality. If you do need to have the key re-programmed, make sure you have all the keys so that they can all be done at the same time. Most local shops do not have the capability to access the immobilization systems on these vehicles.

After ages searching finally found this on the Cobra site.... A8510 KEY PROGRAMING Ensure the immobiliser is disarmed :- 1) Switch the ignition ON and OFF three times then back to the ON position within seven seconds. 2) The LED on the dashboard will light up signaling the unit is in programming mode. 3) Touch an already programmed key onto receptical, the LED will extinguish for one second 4) Repeat step 3 for all other keys (Max of 4 touch keys) 5) To exit programming switch off the ignition key (unit will automatically exit programming after four keys) NOTE :- 1) Programing procedure can only entered with the system disarmed. 2) If all keys have been lost the system will need to be replaced

If the EKA code contains a 0, then you have a problem that should never have got to you - the dealer should have spotted the duff EKA and changed it! I have no idea how you'd get it back from such a state, other than programming a new BCU to the engine ECU, and then new keyfobs to that BCU. This is assuming the 0 isn't just a mis-print or an 8 ? Best to get the dealer on this.
(In order to access security you have to insert the key and turn to position I and I don't think the system would let you in until it was disarmed)

The RCDLR (remote control door lock receiver) could have failed, or the battery in your key fob is dead. The only way to get the immobilizer off is to use the key fob.
