Principle of remote control lock
The infrared signal or electromagnetic wave signal sent by the remote control lock from the transmitter is received and transmitted to the door lock remote control in the control component. The door lock remote control component compares and determines the signal received by the receiver. If it is a correct code, the circuit will alternately input the door opening or door locking signal to the automatic door lock control component through its internal output, through the door lock motor or electromagnetic The iron comes to complete the door opening or locking action. If the door lock remote control component continuously inputs an incorrect code, the door lock remote control component will stop input within a certain period of time through the limited time lock circuit in it.
Are remote control locks safe
In the past, because remote control locks were relatively expensive, they were originally used on cars and motorcycles. Nowadays, people’s awareness of home anti-theft has increased, so remote control locks have also begun to be used in homes, hotels and other places. Remote control locks are the best anti-theft locks available. High-skilled thieves and employees of professional lock-picking companies are basically unable to open the commonly used mechanical locks with iron wire, master keys and some tools. Some even open the locks in a shorter time than the owner of the key.
1, safer – invisible lock, thieves have no way to start.
2. More convenient – you can unlock the lock with just one click. Even if there is no light at the door at night, you don’t have to worry about the key not fitting into the lockhole.
3 More worry-free – when guests come, you don’t have to go downstairs to unlock the door yourself, just press it lightly.
4. Simpler – easy to install, plug and play; integrated design is more convenient.
5 Save money – if the remote control falls off, don’t worry, just delete it, no need to replace it with a new lock.
Reasons for alarming after remote control locking
1. After the vehicle is automatically locked, the vehicle alarm is in an armed state.
2. When the vehicle alarm cannot detect the front-end sensor or the front-end sensor sends an alarm signal, the vehicle alarm will then sound an alarm.
3. Check whether the 4 doors are closed, the windows are closed, the car is turned off, and the gear isWhether to return to the correct gear.
Causes of remote car lock failure
1. Generally, car remote lock fails. It may be caused by the car body or the remote control key itself. The time control module in the remote key is malfunctioning, the battery is dead, and the antenna of the remote transmitter in the car is aging, etc., which may cause the remote key to not work. This requires the car owner to promptly go to the 4s store or professional repair office to check and find out the problem when the remote control key fails, and determine whether there is a mechanical problem.
2. Due to the cold weather, part of the remote control is greasy and thickened, resulting in poor contact, causing the car remote control lock to malfunction. Therefore, car owners are advised to keep their car’s remote control key properly to prevent oil contamination from entering.
3. Another possibility for the failure of the car remote control lock is that there is strong magnetic field signal interference around the car parked. Because the smart key uses low-intensity radio waves, it may not work properly in the presence of magnetic field interference. Many criminals may hide around the vehicle and use signal jamming equipment to interfere with the normal use of the remote key and steal valuables or the vehicle.
