Disabling autorun on Sherhan Magicar 5: 5 proven methods

Car owners Sherhan Magicar 5 often face the need to disable autostart - be it due to a low battery, false alarms, or seasonal adjustments to settings. This function, despite its convenience in cold weather, can become a source of problems: from unpredictable engine starting to conflicts with the immobilizer. Unlike budget alarms, Magicar 5 offers several ways to deactivate autorun, but not all of them are obvious to the user.

In this article we will look at 5 working methods - from basic (via key fob) to advanced (soft reset). We will pay special attention hidden menu settings 9.5 and 9.6, which the manufacturer does not advertise in the official instructions, but which allow you to flexibly configure the autorun logic. You will also learn how to avoid mistakes, for example, when the alarm ignores commands from the remote control or “freezes” in standby mode.

1. Disabling autorun via key fob: step-by-step algorithm

The fastest way is to use a standard key fob Sherhan Magicar 5. However, there are nuances here: if the alarm was installed unofficially, the button combinations may differ. We will describe universal sequence, which works on 90% of firmwares.

You will need:

• 🔑 Main key fob (with LCD or LEDs)
• 🔋 Started engine (to check the result)
• 📱 Phone with a stopwatch (for accurate timing of delays)

Instructions:

1. Click the button I (close the car) and hold it 5 secondsuntil 2 siren signals sound.
2. During 3 seconds after the signals, press the combination: II → III → I (open → trunk → close).
3. Wait one long siren confirmation - this means that autorun is deactivated.

Make sure the auto start indicator on the key fob goes off

Try starting the engine from the key fob - the lock should work

Check the response to the temperature sensor (if temperature trigger was configured) -->

⚠️ Attention: If after manipulation the key fob gives an error E4, which means the alarm blocked the commands due to an incorrect sequence. In this case, it will only help hard reset (see section 4).

2. Configuration via the service menu: hidden options 9.5 and 9.6

Manufacturer Sherhan hid some functions in the engineering menu, which can be accessed through a special combination. There are options available here that are not in the standard settings of the key fob, including flexible autorun settings by time, temperature and battery voltage.

How to enter the menu:

1. Turn on the ignition (without starting the engine).
2. Click the button Valet (hidden button under the panel) 7 times at intervals 1 second.
3. After the 7th press, hold the button Valet up to 3 beeps.
4. The inscription will appear on the keychain Menu - you are in engineering mode.

Next:

• 🔢 Dial the code 95 for autostart menu by temperature or 96 to run on a timer.
• 📛 Use buttons I and II on the keychain to navigate through the items:

⚠️ Attention: After menu changes 9.6 alarm may require reboot. To do this, turn off the ignition, open/close the driver's door and turn on the ignition again. If the indicator on the key fob blinks red, the settings have not been saved, repeat the procedure.

3. Software shutdown via CAN bus (for advanced)

If your Sherhan Magicar 5 connected to the vehicle's CAN bus, autostart can be deactivated via the OBD-II diagnostic connector. This method requires:

• 🖥️ Laptop with program Sherhan Configurator (version 2.14 or later)
• 🔌 ELM327 or K-Line adapter (depending on the car model)
• 🔑 Access to alarm service codes (usually indicated in the device passport)

Step by step instructions:

1. Connect the adapter to the OBD-II connector and start Sherhan Configurator.
2. From the menu, select Connect → Auto Detect.
3. After determining the alarm model, go to the section Autostart Settings.
4. Uncheck the following items:
   • ✅ Enable by Temperature
   • ✅ Enable by Timer
   • ✅ Enable by Voltage

💡 Helpful tip: Before connecting to the CAN bus turn off the ignition and remove the key from the lock. Otherwise, the alarm may regard the diagnostic request as an attempt to steal and block the engine.

4. Hard reset: when all else fails

If the alarm Magicar 5 “stuck” in autorun mode and does not respond to commands, remains full reset to factory settings. This method erases all user settings, including key fob binding, so use it as a last resort.

You will need:

• 🔧 Screwdriver for removing the panel (if the button Valet hidden)
• 📝 Reset code (default 1111 or 0000)

Instructions:

1. Turn on the ignition (without starting the engine).
2. Click the button Valet 10 times at intervals 0.5 seconds.
3. After the 10th press, hold Valetuntil they sound 5 siren signals.
4. Enter the reset code using the key fob:
   • Click I 1 time (digit 1)
   • Click II 4 times (digit 4)
   • And so on, according to your code.

⚠️ Attention: After the reset, all key fobs will be untied. To rebind them, within 10 seconds After reset, press any button on each key fob. If you skip this window, you will need to reset again.

5. Mechanical shutdown: when the electronics fail

If the alarm system is completely out of order, but continues to send commands to start the engine, it remains physical shutdown autorun module. This method requires knowledge of the wiring diagram Magicar 5 to your car.

Where to look for the module:

• 🚗 It is usually installed behind the dashboard or under the glove compartment.
• 🔌 Look for a box with the inscription Sherhan Brain or Control Unit.
• 📡 The autostart module can be removed separately (black block with connector J4).

How to disable:

1. Disconnect red wire (power supply +12V) from the autostart module.
2. If the module is integrated into the main unit, locate the fuse F3 (usually 10A) and remove it.
3. To completely deactivate, disable blue wire (tachometer signal) and yellow (ignition).

⚠️ Attention: After a mechanical shutdown, the alarm will remain operational, but will lose its autostart and turbo timer functions. To return them, you will need to reconnect and configure through the menu 9.5/9.6.

Common mistakes and how to avoid them

Even experienced car owners make mistakes when working with Sherhan Magicar 5. Here are the most common:

💡 Helpful tip: If, after disabling autostart, the indicator on the key fob lights up Check Engine, this is not an engine error, but a signal of an alarm conflict with the ECU. Perform the synchronization procedure:

1. Turn on the ignition.
2. Click Valet 3 times.
3. Start the engine with the key - the indicator should go out.
