Simon_CSK Posted March 14, 2022 Share Posted March 14, 2022 I have bought a Disco 3 without keys. I have had a new key made to allow me to turn on the ignition however I have no engine management light illuminating and the car will not crank. How do I sort this, where do I start problem solving and is there a temporary work around. Quote Link to comment Share on other sites More sharing options...
L19MUD Posted March 14, 2022 Share Posted March 14, 2022 Do you mean you have a key that turns the ignition but which you have not coded to the car yet? A decent auto locksmith should be able to code the key for you You don't make your life easy! Quote Link to comment Share on other sites More sharing options...

The autolocksmith has done the key and he is the one saying that there is no power to the ECU Quote Link to comment Share on other sites More sharing options...

Did you just get a blank cut or buy a new fob and and get the blank cut. The issue you have seems to reflect that it is not turning off the immobilizer - does you new key have the immobilzer chip fitted (is different to the electronics to unlock doors etc) - both need to be programmed to the car.

Garry I got a local vehicle locksmith to the pick the lock which made a key to fit. He then took the BCU and put a new "resistor" in it before returning the key and the BCU to me stating that the key should now start the car. It doesn't and he says the EML is not coming on so there is an electrical supply issue to the ECU. Quote Link to comment Share on other sites More sharing options...
garrycol Posted March 15, 2022 Share Posted March 15, 2022 Ok - thanks - not following at all - BCU? The BCU is the Body Control Unit that controls the functions related to the car body and it talks to other car ECUs including the Engine Control Unit - you need a new complete key fob with all its electronics and immobilizer chip that then need to be coded to the car. Not sure what the EML not coming on has to do with the problem. On start the EML along with all the other dash lights come on as a bulb check but the EML itself will not come on when starting if there are no issues. Anyway it is not clear to me what you have, are doing and what the issue might be. Good luck with it. Quote Link to comment Share on other sites More sharing options...
Arjan Posted March 16, 2022 Share Posted March 16, 2022 It sounds as if you have the vehicle still in the "immobilized " mode. Knowing the D3 you'll need to take it to the dealer / specialist with the correct computers to make the thing talk to your new remote and the key to disarm it and accept the transponder in the key - 2 very different things. But you'll need to have some good paperwork to show and proof to them on how you legally became the owner of the vehicle before they'll touch it. Bon Courage !

To do anything on a D3 you are going to need a code reader/programmer circa £450 new, they will program keys aswell as all the ECUs etc without you are just guessing.
