How do i fix my car engine cranking but won't strat. code immobilizer not response.

start by scanning vehicle for trouble code --fixing battery issue --resetting or reprogramming fob/security system

B1523 Suzuki Keyless entry circuit failure need to test and check ignition system--keys--wiring --etc

not cranking indicates a battery problem
not starting indicates a sensor or immobilizer problem
the transmission codes and traction codes are required to get fixes
try giving details like make , model, year engine type, and equipment type next time as what you have is virtually useless to get an answer

Did who checked the engine, did he check spark plugs? Give it a shot to check if they are ok or do they need replacement.

Do you have the year make and model.? If it is a anti theift with a key immobilizer the vehicle will just start and idle for a few seconds then shut off and the anti theft light will remain on or be blinking. Then we know you are dealing with the anti theft. do you have another key to crank the engine if you do use a spare key and hold the key next to the immobilizer and crank the engine see if that will give if it doesnt try this method. roll the window down with window down disconnect the negative battery cable wait 5 minutes reconnect put the key in the ignition but dont crank it just yet turn it in the on spot not the crank for 2 minutes then crank it and see if that start the vehicle . If this doesnt work then you will need to call a mobile locksmith who reprograms the immobilizer

Everytime when you had a new key you must programm all available ignition car keys before trying to start the engine with this new key !!!

First of all you need to programm all ignition keys using suitable diagnostic equipment (VAS, VAG-Com) connected to the data link connector of the car.

You have an electronic immobilizer key recognition problem. Now your key chip is not recognized by the transponder antenna fitted on the ignition switch barrel.



This warning lamp indicates that the engine is locked by the immobilizer system, and the engine start sequence must be repeat again.

From year 1995 in Audi-VW (VAG) cars is used engine immobilizer. The VAG group immobilizer system consists of an immobilizer ECU which controls the recognition of keys and the Engine Management ECU system. Immobilizer is activated when the ignition key is removed and, together with the engine control unit, largely prevents unauthorized starting of the engine. The system uses a transmitter and receiver unit in the ignition key (transponder). Whenever an attempt is made to start the engine, it transmits a new code to the car's electronics. The immobilizing is only cancelled and car motor electronic receives permission to start engine if the key sends a right authorization code.

have scanned if light is on. it may be a bad or failing crank sensor. for the sensor controls timimg, it will stop engine while driving. have a good day!!

Check the wires on the alternator
