My Key Won’t Turn Ignition Mercedes-Benz Problem

Interior vibrations Mercedes BenzYou insert the key in the ignition of your Mercedes-Benz, but nothing happens. You can’t turn the key. You can’t start the car. The main reaon why this happens is a dead battery, but it can also be several other problems which we have described below. As you insert the Smart Key remote into the Electronic Ignition Switch(EIS) control module (N73), power is supplied to the key by the induction coil ring located in the EIS. Data is then exchanged with the infrared transmitter to validate the Drive Authorization. This article goes over the main reasons why the key won’t turn in the ignition and possible solution.

Mercedes EIS / EZS Immobiliser Key Module Problems

  • Unable To Turn The Key
  • Unable To Start The Car
  • Can Turn The Key  but the car will not start
  • Ignition Key Faults

Drive Authorization System (DAS) is the Mercedes Immobilizer system which checks drive authorization every time you insert the key into the ignition and try to start the car. DAS was introduced back in 1996 and has had several security improvements. The main DAS versions DAS are DAS 2, 2A, X, 3.

List of common problems and possible solutions

New drivers always experience this at least once, so we thought we would include it in this list. If the key does not turn in the ignition, try moving the steering wheel as you try to turn the key. The steering wheel will feel completely solid if you try to move it in one direction and may move slightly in the opposite direction. Push the steering wheel in the direction that allows a little movement and then insert the key and try to turn the key again. You can put pressure on the steering wheel and also try shaking the steering wheel. As you do this insert the key into the ignition and try to turn the key. DO NOT TRY TO FORCE THE KEY IN THE IGNITION. The steering column lock is a security feature which all car manufacturers incorporate in the cars.

  • Discharged Battery  Undervoltage

It is possible that the battery in the car is defective, as it does not provide the necessary voltage for the ECU and  the N73 Electronic Ignition/Starter Switch (EIS)  to function properly. If the battery is dead or has low voltage / under voltage, the CAN communication between EIS and N72 may not function properly.  The EIS in the Mercedes-Benz has a coil that induces a magnetic field on the Smartkey wich causes the key to respond to the car with a specific rolling code. Using a $10 dollar multimeter like this one, you can check that you have a good battery before you proceed further. The car battery should indicate at least 12.8 volts without the car running. When the engine is running it should be over around 14.4 volts. If you need a replacement battery for


If you have a metal blade key instead of the Smart Key Remote, it is possible that the key tumbler could be defective. While most Mercedes-Benz cars have the SmartKey some models such as the ML Class, SLK Class, Crossfire used a metal blade key up to 2005. Some models suffer from the defective key tumbler. We have seen cars with as little as 20,000 miles where the tumbler go bad. Make sure the steering wheel is not in a locked position as mentioned above. Then insert the key into the ignition and gently jiggle the key without putting much pressure on the key as do this. As the lock pins on the tumbler wear out it will get harder and harder to turn the ignition of your car.  Here is a video that will help you understand this problem. The video below shows the same problem on a GM, but the same principle applies to the older Mercedes-Benz that use a metal blade key.

  • Defective Electronic Ignition/Switch System EIS / N73

The EIS module could also be the reason that the key does not turn when inserted in the ignition. Many car owners complain that the car starts fine on a warm or hot day but in cold days the car will not start. This may sound strange, but it is reported frequently. The EIS has processors soldered on the circuit board and in many cases the connections for the processor could be bad or the processor itself is defective. In the video below you can see how the cold temperature causes the ignition switch to not work properly. The ECU could experience the same symptoms as well.

If you have this problem you will have to install a new / virgin EIS. You can not install a used unit because the EIS has to be paired / married to the car using Mercedes-Benz Star Diagnostic Software.

They key itself may be the reason why the car doesn’t start. The key may open the doors, but it will not start the car. In some cases, the transponder coil wires may disconnect and need to be resoldered or the processor in the key could be defective. The simplest solution, in this case would be to order a new key from the Mercedes-Benz dealer. Read What you need to order a new key for your Mercedes-Benz.

  • Defective Electronic Control Module (ECU)

Electronic Control Module (ECU) is another reason why the car doesn’t start. You will need to get a new ECU installed to solve this problem. You can not swap with a used ECU and expect it to work as the board is “married” to the car. Another solution would be to get a used ECU and switch the processor from the old circuit board to the used replacement ECU. Watch this video and see how MBCluster user on Youtube successfully cloned a Mercedes-Benz ECU!

Also consider:

  • Cleaning the EIS keyhole with a dry cloth. Do not use liquid to clean the EIS.
  • Checking Fuses

NOTE: Avoid letting the car’s battery discharge while the key being in the ignition. This could damage the key or the EIS.

The new, second fuel flow meter the FIA has added to Formula 1 cars this year is designed to prevent a trick Ferrari is believed to have used last season.

Ferrari insists its car conformed to the rules throughout 2019. However rival teams have criticised the FIA for reaching a settlement with the team without disclosing details of its investigation, part of which is believed to have concerned the fuel flow rules.

Since 2014, F1 teams have been required to fit a fuel flow meter which ensures their power units do not consume fuel at a rate greater than 100kg per hour. However last year some teams began to suspect Ferrari had found a means of exceeding the limit.

One theory held that Ferrari had developed a system known as ‘aliasing’ which could allow them to deliver fuel at a higher rate when needed, such as on qualifying laps.

The fuel flow meter measures the rate of flow very quickly – 2,200 times per second. However it remained theoretically possible for teams to deliver fuel to the meter in a sufficiently precise way that it appeared to be flowing at a slower rate that it was.

One technician consulted by RaceFans estimated the potential power gained from aliasing could be as much as 50bhp.

Last year Red Bull asked the FIA to clarify whether teams were allowed to use such a technique. The FIA responded by issuing a technical directive ahead of the United States Grand Prix stating it would be illegal. During that weekend Ferrari’s previous straight-line speed advantage appeared to have lessened.

The most recent version of the 2020 Formula 1 technical regulations, published 10 days ago, continues to refer to “a single fuel flow sensor” in the cars. However teams have been required to fit a second sensor under a further technical directive.

There are two important differences between the new fuel flow sensor at the original one. The new ‘FIA fuel flow meter’ samples the fuel flow rate in a different way, making it harder for teams to get around the limit, and the data it generates is encrypted and available only to the FIA.

Manufacturer Sentronics says this will make it “impossible” for any team to exceed the fuel flow limit.

“The new device incorporates anti-aliasing technology and full data encryption,” according to Sentronics. “The anti-aliasing technique randomises when the device makes its measurements, ultimately making it impossible to synchronise any ancillary parts to the measurement frequency. Full encryption ensures the authenticity of the data and privacy to the FIA.

F1 fuel flow sensors
“This eliminates the possibility of the data being used as part of a feedback system to gain a competitive advantage.”

The new fuel flow meter was added to the cars at pre-season testing and will continue to operate alongside the existing device. The FIA will retain a pool of the new meters and allocate a sensor to each car at the beginning of each event.

“This new variant of the FlowSonic fuel flow meter is not only one of the most technologically advanced currently available, but is an important step forward in improving the FIA’s policing of the maximum fuel flow regulations in F1,” said Sentronics managing director Neville Meech. “We’re proud to lead the market in solid-state fuel flow meters, and to demonstrate our ability to develop world-class technology in rapid timeframes.”

The FIA announced last month it had reached an settlement with Ferrari following its investigation into their power unit but would keep details of its finding secret. This prompted an angry response from the seven non-Ferrari-powered teams, who have demanded clarifications from the FIA as to whether Ferrari operated within the rules at all times last year.

In a further statement, the FIA admitted it was “not fully satisfied” Ferrari’s power unit operated “within the limits of the FIA regulations at all times” during 2019. The careful wording indicates they suspected not that the power unit was illegal, but that it may have operated outside the rules at certain times.

Ferrari “firmly opposed the suspicions and reiterated that its [power unit] always operated in compliance with the regulations,” the FIA noted. Of course, this did nothing to placate the seven teams who complained.

As those teams already had details of the new fuel flow sensor, the fact it is so clearly aimed at preventing anyone getting around the fuel flow rules shows why their suspicions were so strong.
