Immobilizer on Mercedes ML
On Mercedes ML machines, a problem often arises – on a discharged battery, when the starter scrolls, the chip key flies and the engine does not start. This is because the chip key has two components of the program code: constant and variable. Its constant component does not change, and the variable changes with each start.
When scrolling on a dead battery, the chip key does not fully receive the variable component data, and the next time the ignition is switched on, the immobilizer no longer recognizes this chip key. If such a problem occurs, charge the battery and then try using a different key..
If you have only one chip key, then in case of breakage or loss, the authorized dealer will offer you to replace the EAM or AAM unit, which can cost you a pretty penny. It is much cheaper and easier to contact any other specialists..
For this, the EAM or AAM block removed from the car is enough, which depends on the year of manufacture of your car.
Mercedеs Infrared Remote Control
On older Mercedes cars, the full-time immobilizer was controlled using a remote control. The remote control was an infrared transmitter, in which the receiving element was next to the rear-view mirror. And on the rear view mirror there were indicators of the status of the standard immobilizer of red and green colors.
When the car is opened with the remote control, the immobilizer instructs the engine to allow the engine to start. But, the remote control may fail and cannot be repaired. Well, if at that moment the car was in UNLOCK mode, i.e. was opened with the remote control. In this case, the engine will start.
If the remote control fails when the car is closed (LOCK mode), the engine will not start. In this case, you must either transfer the immobilizer to UNLOCK mode or tie up a new remote.
The key is the fish Mercedes. Repair of the ignition lock Mercedes
Mercedes owners sometimes encounter the problem of starting the engine due to the failure of the DAS-DRIVER AUTHORIZATION SYSTEM system. This system includes the following electronic components: a control unit with an engine, an electronic steering column lock ELS, an EІS ignition lock, and a smart key called a “key fish”.
The main malfunctions of this system are the malfunction of the ignition key and the synchronization of the electronic steering column lock with the ignition switch. Also, the key itself may partially lose program data due to weak batteries. In this case, the car will not start.
If the smart-keu fails, it is possible to conduct a diagnosis of its performance and, if necessary, repair. To do this, just provide the ignition key. If the key fish really turns out to be faulty, then its repair will take no more than 1-2 hours.
If the key turns out to be working, then you need to either provide the car itself, or remove and bring the electronic steering column lock and ignition switch. A control unit may also be required if the car is manufactured after 2001..
If the last key is lost, you can purchase a new key fish. There are fish: for European cars with a frequency of 433 MHz, for American cars with a frequency of 315 MHz. Also, the new key adapts exactly to your car.
Mercedes W212 fish key with a frequency of 433 MHz for European Merces can be used on the following models instead of old fish: VIANO, W639-VITO, W210, W208, W202, W209, W211, W220, W203. In addition to modern design, there is one more plus: the buttons on the key will not be pressed, as on old Mercedes fish.
Mercedes W212 fish key with a frequency of 315 MHz for American Merces can be used for: W210, W208, W202, W209, W211, W220, W203. This key, unlike the European one, additionally has a “PANIC” button.
Mercedes Chip Key
Old Mercedes cars, unlike new ones, have an ignition key with an electronic chip sealed in the key head. This chip key is used in cars such as Mercedes Vito, Sprinter, W210, ML, etc..
If the last chip key is lost, you can order it from an authorized dealer or perform restoration according to the data of a regular immobilizer. In order to make a Mercedes chip key according to the data of a standard immobilizer, a standard immobilizer must be removed and handed over to specialists.
Most often, a regular immobilizer on old Mercedes cars is located behind a combination of devices.
