Default engine immobilizer

Hi All
Anybody help before I burn this dam thing,went to start car this morning battery reading 11.9 volts ,turned on ignition went to second position, engine immobilizer warning came on(car as not been used for two weeks) used other key,same result.Worked perfectly last time car started, same keys same batteries (one new).Have another !2v battery on charge although I can:t see that makes any difference but you never know.I do have another key and ( I think ) an immobilizer ecu from a spare car I had ,possible to swap chip and ecu over! Any help appreciated.

Best to re-charge and try again before resorting to a spare ECU. You will need a minimum of main ECU, EWS (immobiliser ECU) and transponder chip (in the keyfob) from the same car for it to work.

My car doesn't even attempt to turn over below 12.3 volts on the battery.

Modern cars need a healthy battery, anything less than 12v won't cut the mustard

Yes, remove the EWS from the car, post it Special Delivery to either me or Russ, and a couple of new transponders can be programmed for you.

Take a look HERE or indeed a trip down memory lane HERE
