View My Garage. First of all, I want to express a sincere thanks to a fellow forum member, Roberto Baggio aka RobertoBaggio I would have neither had the courage to do this nor would I have had the information necessary had it not been for Roberto. He found a link to a fellow that had information about bypassing the security system on the car.

If I did not have this, I would not have been successful. So again, thanks Roberto. My E36 would not start about 6 months or so ago. I was in no hurry to fix it as this is a spare car. I probably would have been done a lot sooner, but I had to have knee surgery in early December and that really slowed me down. Now, on to the story. I have a is with K miles. This has been a very good car and has only had about 4 no-start situations.

The first was a failed fuel pump. I had it towed to a mechanic. I had an old 85 Mercedes D that I was not a bit afraid to work on. I would adjust valves and service the transmission etc. I know, it was silly, but all I would do at first is change the oil. Anyway, I found Bimmerfest and as the saying goes, the rest is history. The second no-start situation was a bad fuel pump relay.

I removed the air filter and squirted a little starting fluid into the intake. It started for a couple of seconds, but would not respond to the throttle. I replaced the fuel pump relay and all was well. After that, it would not crank. The first thing I checked was the fuel pump relay, but that was not the problem. I had no fault codes stored in the ECM. I messed with it for about an hour but it still would not crank.

On the last try, it coughed a little and finally cranked. The frustrating part was, I never did figure out what caused it to not crank.

I continued to drive the car for another year with no problems. It would turn over, but it would not catch and run.

So, I started the usual process of diagnosing it thinking that it would be an easy fix. I was so, so wrong.An Immobiliser or the Engine Immobiliser is an electronic security device which the modern cars use. This system uses a special digitally coded key or a Smart Key fob. This key contains a transponder chip. When the driver inserts this digital key into the ignition switch or takes the Smart Key fob inside the vehicle, the key transmits the electronic code to the Engine Management System of the vehicle.

The engine can start only if the code in the transponder chip inside the key or Smart Key fob matches with the code in the engine immobilizer. A permanent personal code and a changing second code. Each time the key starts the engine, the system changes the second code and stores it in the key.

Whenever the driver switches on the ignition, the immobilizer first reads the personal code. Then, it requests for the second rolling code. After both these codes match, only then the immobilizer sends another coded signal to the Engine Management System to unlock the engine. Without this, the engine does not start. In the absence of the second security code, still, the engine will not start even if someone tries short-circuiting the ignition circuit.

Thus, it prevents the vehicle theft. Since the transponder chip is embedded in the key or Smart Key fob, it cannot be easily duplicated. In case of loss of the key or Smart Key fob, only the authorized dealers can deactivate the lost key. CarBikeTech is a technical blog with experience of over 20 years in the automobile field.

Some cars have alarm systems which send out SOS signals to a cell phone number in case of breakdown or theft. Alarm systems are also incorporated within a navigation system to increase the security of the car.

The navigation system will send out a ping signal so the car can be received. The security system can also be used to locate the car in large parking lots by using the conformation chirp on the remote fob.

Sometimes a car alarm can give out a false alarm when it feels vibrations of thunder or a passing truck. Sensors need to be adjusted properly otherwise it can trigger the device even when a person accidentally touches the automobile as well. For people who want added security for their cars can have a police tracking system installed with the help of services like On Star. These systems come with an additional cost which is to be paid on a regular basis.

ECU Chip Tuning.I've been seeing a number of posts on the forums and I've gotten at least a dozen calls from E46 owners that are having problems with their key not starting their car.

In particular the EWS - Immobilizer not allowing the car to start. The keys that came with the car have a small transponder chip in them even the valet key which doesn't have buttons which gets read by the car when the key is in the ignition. The transponder gets it's power from the EWS pickup coil located around the ignition switch. The code sent by the transponder is picked up by the EWS coil and compared with a list of good codes programmed from the factory.

If it's not on the list the EWS deactivates the starter motor. Everything will still work, radio, lights, doors, windows, everything.

Just not the starter motor and you can't push start the car either since it tells the DME not to fire the injectors. In some cases the car will intermittantly start with only 1 of the keys, the other keys start the car fine. In this case the problem is repairable with my key repair service.

Be sure to let me know that the key is a no start key. It only powers the keyless entry portion of the remote lock, unlock and trunk release functions.

Another one is recoding the key to the car will help See recoding procedureNO, No it won't. The recoding procedure only codes the general module to the key for keyless entry, again it had nothing to do with the EWS system and will not help.

Rectangular keys like the one below do not have a key resync procedure and this also goes for diamond shaped keys for E60 or E For the first generation diamond shape key E39, E46, E52, E53, E83 and E85 the EWS transponder coil is 7 in the picture below and works in conjunctions with several other components on the board to support the immobilizer function.

If you are looking for a new key that will be able to start the engine you will need to buy from BMW. Any of the keys will start the engine, plastic wallet key, valet key or master remote key. If you have the plastic wallet key or the valet key I might be able to turn that key into a remote key for a lot less than the dealer.
