Operating a modern car with an alarm system Scher-Khan Magicar 5 provides the owner with ample opportunities for remote control, however, in certain situations, the automatic engine start function must be deactivated. This may be due to the need for maintenance, refueling, or simply the driver’s desire to independently control the process of warming up the engine in winter. Understanding the logic of the safety system will help you avoid unexpected engine starters and ensure comfortable use of the car.
The shutdown procedure depends on which mode is currently activated: periodic start by timer, start by temperature, or one-time start from the key fob. The owner must clearly distinguish between these states, since the algorithm of actions for each of them has its own technical features. The wrong sequence of button presses can cause the system to remain in active mode, which sometimes causes confusion for inexperienced users.
In this guide we will look in detail at all the available ways to control the autorun function for the model Magicar 5. We will look at both software settings through the key fob menu and emergency shutdown methods, and also pay attention to the important nuances of the operation of temperature and voltage sensors on the on-board network.
Basic operating modes of autostart Sherkhan 5
System Scher-Khan Magicar 5 supports several independent automatic engine start algorithms, which can work simultaneously or separately. The first and most popular is the periodic start mode, which is activated by a timer every 2, 4, 8 or 24 hours. The second important mode is starting the engine when the ambient temperature drops below a set threshold, which is critically important for northern regions.
The third option is a one-time launch on command from the key fob, which is often confused with automatic mode, although technically these are different functions. There is also the possibility of triggering based on a voltage drop in the vehicle’s on-board network, which allows you to maintain the battery charge during a long period of inactivity. For correct control, you need to understand which function is active in your case, since the indicators on the key fob screen display the status of each mode separately.
It is important to note that the system has priorities: if temperature and timer triggers are set at the same time, they will be executed in order of priority or according to the controller logic. Programming These parameters are carried out through a special key fob menu, which is available only when the security mode is turned off.
Technical nuances of the controller
The alarm controller constantly polls the temperature and time sensors, even when the car is in sleep mode. This means that the key fob battery and vehicle battery must be in good condition to correctly track startup events.>
Disabling periodic timer launch
If your car starts on its own at certain intervals, then the periodic start mode is activated. To turn it off on the key fob Magicar 5 it is necessary to perform a sequence of actions that will reset the current timer settings. Most often, users accidentally activate this feature by long pressing a button combination.
To deactivate the timer, look for an icon in the form of a dial or letters on the key fob display RUN, flashing in a certain mode. The standard procedure requires pressing and holding the buttons II and III simultaneously for two seconds. Successful shutdown will be confirmed by a melodic signal from the key fob and the disappearance of the corresponding symbol from the screen.
☑️ Checking whether the timer is turned off
Please note that once the timer is turned off, the system will not automatically start the engine until you program the interval again. If the car is parked outside in extreme cold and you turn off the timer, monitor the coolant temperature to prevent freezing.
Start control based on engine temperature
Temperature trigger function (TEMP) is one of the most useful in winter, but it can also be a source of unexpected triggers if the threshold is set too high. The system reads data from a sensor installed on the engine and compares it with a value set in memory. If the temperature drops below minus 15, minus 25 or minus 35 degrees (depending on the setting), a start occurs.
To completely disable this function, you must enter the key fob programming mode. This is done by long pressing the buttons I and II. After entering the programming menu (indicator FUNC flashes) you need to press the button briefly III select the function responsible for the temperature threshold. Usually this is Function 15 or similar depending on the firmware version.
Having selected the desired function, press the button Ito cycle through the values. You need to get to the meaning OFF or the maximum threshold at which starting is virtually impossible in your climatic conditions. After selecting a value, wait until the menu automatically exits or confirm your button selection.
Resetting a one-time start from the key fob
Sometimes a situation arises when the start command was sent accidentally, and the engine has already started running, but you urgently need to turn it off or cancel the command before the starter starts rotating. If the engine is already running, just press a combination of buttons to stop it II and III on the keychain. This is a standard "Stop engine" command, which works regardless of the security status.
If you just pressed the start button (button I for 2 seconds) and saw the indicator on the key fob flashing, but the engine has not started yet, you can cancel this cycle. To do this, press the button again I for a short time or use the combination to disarm if the system logic allows interruption. In some firmware versions, pressing the start button again acts as a toggle.
It is important to distinguish between the state when the system is “waiting” for startup (counting down before the start) and the state when the engine is already running. In the first case, disarming or opening the door helps (if the “Turbo” mode or similar delays are not set). In the second case, only a command to jam is required.
Scher-Khan 5 key fob button combination table
For the convenience of users, below is a summary table of the main commands associated with engine control. Memorizing these combinations will help you quickly respond to changing situations without referring to the instructions every time.
| Action | Button combination | Press duration | Result |
|---|---|---|---|
| Engine start/stop | II + III |
2 seconds | Starting or stopping the engine |
| Entering the function menu | I + II |
2 seconds | FUNC indicator flashes |
| Selecting a function from the menu | III |
Short | Switching the function number |
| Changing the value of a function | I |
Short | Cyclic parameter change |
Please note that all actions with the key fob must be performed in an area with reliable signal reception. If you are far from the car, the system may not receive the command and the key fob will not issue a confirmation signal. In such cases, the communication or antenna indicator may flash on the screen.
Setting the engine operating time and turbo timer
In addition to the fact of launching, the system Magicar 5 allows you to regulate the engine operating time after automatic start. This can be 5, 15, 25 minutes or the “Limited by tachometer” mode (operation until the battery is charged or warmed up). This parameter can also be configured through the function programming menu.
For owners of cars with turbocharged engines, the Turbo Timer mode is relevant. In this mode, the system does not turn off the engine immediately after turning off the ignition and arming, but allows it to run for some time to cool the turbine. Disabling this mode is done through the function menu (usually Function 3 or 4), where the value is selected OFF.
When disabling the turbo timer, make sure that you are not in the “Closed Start” mode, when the keys remain in the cabin and control is carried out only by the key fob. Abruptly disabling the ignition support functions may result in the car stalling immediately after the key is removed if the algorithm was configured differently.
⚠️ Attention: Before carrying out any electrical work under the hood or inside the car, be sure to disconnect the negative terminal of the battery. Alarm Scher-Khan has complex logic, and accidental shorting of the wires during active power supply can lead to the controller burning out.
Common problems and methods for solving them
Users often encounter a situation where autorun is not disabled using standard methods. This may be caused by “sticking” of the buttons on the key fob due to moisture or discharge of batteries. First of all, always check the battery charge in the key fob - a weak battery may send distorted signals or not transmit a command at all.
Another reason could be a malfunction of the door or hood switches. If the system “thinks” that the hood is open (due to an oxidized sensor), it will prohibit the engine from starting or, conversely, will not allow the operation cycle to be completed correctly. Check the door and hood status indication on the key fob screen with the doors closed.
In rare cases, a software failure of the alarm controller occurs. To eliminate it, you can try resetting the system to factory settings (Function 1 in the programming menu), but this will require re-configuring all security and service functions. Resetting all settings to factory values (Factory Reset) is a last resort and requires complete instructions for programming all system functions.
⚠️ Attention: Do not attempt to disassemble the key fob or alarm controller yourself unless you have experience working with electronics. Violation of the tightness of the key fob body will lead to its rapid failure in the winter.
If software methods do not help and the car continues to behave inappropriately, it is recommended to contact the installers or use the “Valet” mode to completely disable the security functions and autostart mechanically through a button in the cabin.
FAQ: Frequently asked questions
What to do if the key fob does not respond to shutdown commands?
First of all, replace the battery in the key fob with a new one. If this does not help, come close to the car (at a distance of 1-2 meters) and try again. There may be radio interference. If this does not help, try removing the terminal from the car battery for 5-10 seconds to reboot the system.
Is it possible to disable autostart if all key fobs are lost?
Yes, this is possible through the mode Valet. To do this, you usually need to turn on the ignition, enter a personal code (if installed) or press the Valet button a certain number of times. The exact procedure depends on how the system was configured during installation and is described in the technical documentation.
Why does the engine stall 2-3 seconds after autostart?
Most likely, the “immobilizer bypass” procedure has not been completed. The system does not see the key in the ignition and blocks engine operation. The reason may also be a malfunction of the tachometer sensor or an incorrectly configured engine control threshold (Engine Operation Control function).
How can you tell if autostart mode is active by looking at the key fob?
On the key fob display Magicar 5 active autorun is indicated by a flashing clock icon (for the timer) or a snowflake/thermometer (for temperature). The indicator may also light up RUN. If these symbols are absent and not flashing, autorun mode is disabled.
Does disabling auto start affect the basic security of the car?
No, security functions (shock response, door opening, engine blocking) work regardless of the autostart settings. By disabling autostart, you prevent the system from starting the engine on its own, but all security sensors continue to function as normal.
