Hi

There is one method you ca try, first ensure the car is unlocked but with the keys out of the car. then disconnect the battery for about 2hrs, overnight if possible. this should reset the car immobiliser and ECU. When putting the battery back on connect the red first then the black i that order.

If no joy get back to me I have a few oher solutions.

Regards and happy new year
Dan

Car wont start


You have an immobiliser issue which unfortunately will require the assistance of a decent auto electrician. The key is not talking to the immobiliser ecu

Have bmw 523 auto will not start,turns over,have charged battery,do i need to reset immobiliser?help,this car cannot be towed i am told because its an auto?


You shouldn't have to reset immobilizer. And your car CAN be towed, if done correctly. It can be towed from the rear. The preferable way is aboard a flat bed.

Battery ran flat on my 'R' reg VW Golf gti while I was away in Australia. The alarm was disconnected a couple of years ago but now the immobiliser seems to have triggered as there is no spark or petrol...


sometimes it depends on the type of allarm, if it is factory fitted they are a nightmare to do as most of the wireing for the allarm is intergrated into the loom, where as if it is an after marked alarm ( one fitted later on ) it shouldnt be to bad but still a long and complicated job to find all the wires and reconnect the originals bypassing the immobiliser/alarm if you are a complete novice this should not be attempted as you could immobilise the car completely, best thing for you to do is get an auto electrician to have a look at it for you, sorry its not much help

I have a 97 528i BMW recently Ive been having problems starting it . When I turn the key it will try to start but wont actually turn over. I have a new battery so Im thinkin its the starter maybe??


It is most likely the immobiliser rather than starter if it does try to start, is it automatic or manual gearbox? If automatic, than try to take the negative cable of the battery and leave for 15-20 minutes without connection, than switch lights on before reconnecting the negative, this resets the computer so it might help. If it is manual, try a push start if the car starts and runs than it is the starter problem, if not than it will be immobiliser problem.

My petrol Peugeot 405 (1995) seems to be immobilised altho when I enter the code on the keypad the light goes green , turn the ignition it makes the immobilised noise and of course wont start. The battery...


Have you tried turning the alarm back on so that it goes off again, lock and unlock the car with your fob now, then enter the code. This is because it might still be in the standard immobiliser mode.

Wont start


Hi
Had a similar problem with my x type 2.5 petrol, only had the car 1 day went to start it nothing happend all the lights came up on the dash but the engine wouldn't start and the immobiliser light stayed on. Spoke to Jaguar they had no idea and I couldn't get it to them. After disconnecting the battery trying to reset the immobiliser phoned and auto locksmith they came out and discovered the end of the key with the blade had lost it's coding and the immobiliser was not disarming, they reprogrammed the key and the car started no problem. As far as i know there is no way past the immobiliser. Hope this helps.
