We will look at how to activate this mode and check its functionality.
Basic functions and capabilities of the key fob
The security complex is controlled through the main remote control with a liquid crystal screen and an additional key fob. Main keychain provides two-way communication, informing the owner about the condition of the car at a distance of up to 800 meters in direct visibility. The device interface is intuitive, but requires some getting used to the button combinations to access the advanced menu.
The second, additional remote control has a simplified design without a screen and serves as a backup control device. It transmits commands over a shorter distance, but allows all basic operations such as arming and disarming. Most functions are activated using sequential or simultaneous keypress methods, depending on the specific scenario.
⚠️ Attention: Do not allow moisture to get inside the key fob body, as this can lead to oxidation of the contacts and failure of the electronics. When replacing batteries, check the condition of the rubber seals.
The system supports various display modes that can be configured through the menu. You can select the siren volume level, the duration of the light signals and the type of confirmation of actions. Kedr 10 auto It also has a vibration alert feature, which is useful in situations where an audible alert is not desired.
- 🔒 Arming is carried out by pressing the closed lock button once.
- 🔓 Disarming is performed by briefly pressing the open lock button.
- 🔇 Silent mode is activated by successively pressing the “lock” and “key” buttons.
- 🔍 Search for a car in a parking lot by double-clicking the button with the image of a speaker.
Installation procedure and connection diagram
High-quality installation is the foundation for reliable operation of any alarm system. Before starting work, it is necessary to de-energize the vehicle's on-board network by removing the terminal from the battery. Connection diagram Kedr 10 auto is standard for systems of this class, but requires careful study of the pinout of the main unit.
The central module should be placed in a hidden place, away from heating elements and sources of moisture. Wiring must be routed inside standard harnesses, using corrugated tubes to protect against chafing. Pay special attention to connecting the door and hood switches, as they are often the cause of false alarms.
☑️ Pre-installation checklist
To connect the lock control channels, it may be necessary to use additional relays, especially in vehicles with negative or positive polarity circuits. Instructions Kedr 10 auto contains color coding of wires, which must be strictly observed. An error in the connection can lead to failure of the comfort unit or the processor module itself.
| Wire color | Purpose | Connection |
|---|---|---|
| Red | Power (+12V) | Constant battery plus |
| Black | Ground (GND) | Car body |
| Orange | Exit to siren | Positive siren input |
| Blue | Door switch | Contact in the doorway |
Use heat-shrink tubing on all twists and solders - this will prevent oxidation of contacts in conditions of high humidity and temperature changes.
Setting the sensitivity of the sensors
One of the most common problems that users encounter is incorrect settings of the shock sensor. Two-level sensor allows you to differentiate between weak impacts (passing by, a gust of wind) and strong impacts. Adjustment is carried out using potentiometers on the sensor body or through the software menu.
To start tuning, you need to reduce the sensitivity to a minimum and gradually increase it, checking the system's response by lightly tapping the body. The first sensitivity level usually causes a siren warning signal, and the second – a full-fledged alarm with a signal transmitted to the key fob. Kedr 10 allows you to flexibly adjust these thresholds to avoid false alarms from loud sounds or vibration of passing vehicles.
⚠️ Warning: Excessively increasing the sensitivity of the shock sensor may drain the battery due to frequent alarm cycles. The optimal setting is a balance between security and the absence of false signals.
If the car is parked on a busy street or in windy weather, it is recommended to temporarily disable the impact sensor or set the system to "Parking" mode. This is done by a combination of buttons on the key fob, which is described in the control section. Remember that even in this mode, basic security functions such as engine blocking remain active.
- 🔨 First level of impact: siren warning squeak and light indication.
- 💥 Second strike level: turning on a full alarm and transmitting a signal to the key fob.
- 🚫 Sensor disable: button combination to temporarily deactivate the sensor.
- 📉Adjustment: Use a screwdriver to rotate the sensitivity screws.
What to do if the sensor does not respond?
If adjusting the screws does not produce results, check the integrity of the wires going to the sensor. Perhaps the contact in the connector has come loose or the shock sensor itself is damaged, which requires its replacement.
Programming new key fobs
If the control panel is lost or damaged, the system allows you to register new key fobs. Binding procedure performed through the Valet button, which is usually hidden in the car interior. To enter the programming mode, you must turn the ignition on and off a certain number of times in a given time interval.
After successfully entering the learning mode, the LED indicator will change to flashing, indicating that the system is ready to record codes. Press two buttons on the new key fob at the same time. Successful recording is confirmed by a characteristic siren sound. Kedr 10 auto allows you to register up to four remote controls, while old codes can be erased depending on the selected algorithm.
It is important to perform all actions quickly and accurately, since the system has a waiting timer. If you do not meet the allotted time between actions, the programming mode will automatically end and you will have to start the procedure again. Make sure that the batteries in new key fobs are fresh and charged, otherwise the recording may not work.
When programming a new key fob, all previously recorded remote controls may be deleted from the system memory, so it is recommended to flash the entire set at the same time.
Remote start and autostart of the engine
The remote start feature is one of the most useful options in winter. Autostart allows you to warm up the engine before leaving or maintain the temperature in the cabin during short stops. Implementation of this function requires proper connection to the ignition circuit and tachometer (or generator) to monitor engine operation.
Autorun parameters are configured through the menu of the main key fob. You can set the duration of the starter operation, engine warm-up time and periodic starting intervals. Alarm Kedr 10 controls the operation of the motor by the voltage level in the on-board network or by the crankshaft rotation speed, which ensures reliable starting in any conditions.
When using autostart on cars with a manual transmission, you must first perform the “soft neutral” procedure. This ensures that the car will remain in gear and will not roll when started by the starter. Ignoring this step may lead to an emergency.
Software neutral sequence:1. Stop the car without turning off the engine.
2. Pull the handbrake.
3. Press the "Close" button on the key fob.
4. Take the keys and get out of the car.
5. Close the doors (the alarm will sound).
⚠️ Attention: It is strictly forbidden to leave a car with the engine running in a closed garage or room without ventilation. Combustion products can be deadly.
Fault diagnosis and troubleshooting
During operation, situations may arise when the system behaves incorrectly. False positives most often caused by a low key fob battery, oxidation of the door switches, or too high sensitivity of the sensors. The first step in diagnosis should always be a visual inspection and checking the battery voltage.
If the alarm stops responding to commands, check the integrity of the antenna module. Any module Kedr 10 is a transceiver, and its damage or disconnection completely disrupts communication with the key fob. It is also worth checking the fuses that supply power to the security system.
The table below shows the main symptoms and how to eliminate them:
| Symptom | Possible reason | Solution |
|---|---|---|
| Key fob not working | The battery is dead | Replace battery |
| Frequent anxiety at night | High sensitivity | Reduce sensor sensitivity |
| Locks won't open | Block failure | Disconnect the battery terminal for 5 minutes |
| No connection to car | Interference or antenna | Check antenna connection |
The system does not see the hood switch
Often the problem lies in the oxidation of the contact under the hood. Clean the contact with sandpaper and lubricate with lithium grease to protect against corrosion.
Frequently asked questions (FAQ)
How to reset Kedr 10 car alarm settings to factory settings?
To reset the settings, you must enter the service mode via the Valet button. This is usually done by turning the ignition on 10 times. After entering the mode, select the reset function (usually Fn10). The system will return to factory settings, and all key fobs will need to be registered again.
Why does the alarm beep when arming?
An audible confirmation may indicate that a door, hood or trunk is open at the time of arming. This may also indicate a malfunction of the limit switches or that the system is in service mode (Valet). Check the indication on the key fob to determine the zone.
Is it possible to install Kedr 10 on a car with a CAN bus?
