Common Malfunctions and Troubleshooting for Remote-Controlled Parking Space Locks

I. The locking rod cannot be raised or lowered (most common malfunction)

Possible causes and solutions

1. Power supply problem

Insufficient battery power (rechargeable/dry battery)

Rechargeable: Connect the charger and observe whether the indicator light is on (if not, the battery may be old or the charger is damaged; the battery or charger needs to be replaced).

Dry battery: Remove the battery to check for leakage or depletion, and replace it with a new battery (pay attention to the positive and negative poles).

Poor electrical contact

Check if the charging port or battery compartment spring is loose or oxidized. Wipe it with an alcohol-soaked cotton swab and reinstall it.

2. Mechanical jamming or foreign object blockage

Foreign objects such as gravel, hair, or leaves are stuck at the bottom of the locking rod or in the guide rail gap.

Manually assist in raising and lowering the locking rod. Use a small brush, toothpick, or air blower to clean the gap of foreign objects. If necessary, apply lubricating oil (silicone grease) to reduce friction.

Wear or breakage of mechanical parts such as connecting rods and gears

Check for obvious wear marks on the parts. Minor wear can be lubricated, while serious damage requires contacting after-sales service to replace parts.

3. Motor or control board malfunction

The motor does not rotate or makes abnormal noise (such as a "humming" sound but no movement)

Non-professionals should not disassemble it. Contact the manufacturer directly to check the motor or control board; parts may need to be replaced.

II. Remote control malfunction or weak signal

Possible causes and solutions

1. Remote control battery problem

Battery power is depleted or contact is poor

Replace with a new CR2032 button battery (commonly used model for remote controls), or open the remote control to check if the battery spring is oxidized, clean it, and reinstall it.

2. Signal interference or blockage

There are strong electromagnetic interference sources nearby (such as transformers, wireless communication equipment)

Temporarily turn off nearby interfering devices, or adjust the installation location of the parking lock (away from the interference source).

The remote control antenna is detached or the main unit antenna is displaced

Check if the remote control antenna is broken (some models have built-in antennas that require factory repair). If the main unit antenna (usually a built-in soft antenna) is loose, it can be refastened.

3. Encoding matching problem

The remote control and the main unit have incorrect encoding (such as multiple misoperations or strong signal interference)

Follow the instructions to perform the "clear code" and "match code" procedures (usually requires long-pressing the main unit setting button, and after the indicator light flashes, press the remote control button to complete the matching).

III. Abnormal noise or shaking when the locking rod is raised or lowered

Possible causes and solutions

1. Lack of lubrication of mechanical parts

Hinges, guides, or gears are dry and worn

Raise the locking rod and apply butter or silicone grease to the moving joints. Raise and lower it 5-10 times to ensure even lubrication. The abnormal noise can usually be eliminated.

2. Base installation is loose

Expansion screws or fixing bolts are loose, causing the parking lock to shake

Tighten the base screws with a wrench. If the ground is uneven, add shims or re-drill holes for fixing.

3. Parts aging or breakage

Plastic shell cracks, metal connecting rod deformation

Minor cracks can be repaired with strong adhesive; serious aging requires replacement of the shell or the entire device.

IV. Automatic return function failure (common in smart models)

Possible causes and solutions

1. Sensor malfunction

Ground sensing coil, infrared sensor, or Bluetooth module malfunction

Ground sensing type: Check if the ground sensing coil is crushed or damaged, and re-lay or adjust the coil sensitivity (adjust through the main unit knob).

Infrared/Bluetooth type: Clean the dust from the sensor surface, ensure there are no obstructions, and restart the main unit before retrying.

2. Incorrect parameter settings

The automatic return time is set too long or too short (e.g., the default is 30 seconds, but it is mistakenly set to 0 seconds)

Refer to the instructions to enter the setting mode and readjust the return time (usually through a combination of remote control buttons).

3. Vehicle detection logic problem

Some vehicle models (such as those with high chassis or electric vehicles) do not trigger the sensor

Try switching the detection mode (e.g., from "ground sensing priority" to "time trigger"), or add auxiliary detection equipment (such as an additional ground sensing coil).

V. Anti-collision function abnormality (smart anti-collision model)

Possible causes and solutions

1. Insufficient sensitivity of the pressure sensor

Sensor surface stains block or sensitivity is reduced

Clean the sensor (such as the rubber pressure strip) and adjust the anti-collision sensitivity through the main unit settings (some models support 3-5 levels of adjustment).

2. Failure to automatically reset after anti-collision

Mechanical structure jamming or return spring failure

Manually assist in resetting the locking rod, check if the spring is loose or broken. If broken, replace the spring (you can contact after-sales service to purchase parts).

3. Alarm function failure

The buzzer is damaged or the wiring is loose

Tap the buzzer to check for a response. If there is no sound, check the connecting wires or replace the buzzer (non-professionals are advised to return it to the factory for repair).

VI. Battery life is drastically reduced (for rechargeable models)

Possible causes and solutions

1. Battery aging

The lithium battery's cycle life has expired (usually 300-500 charge-discharge cycles)

Observe the usage time after a full charge. If it is significantly shorter (e.g., originally usable for 3 months, now only 1 week), the battery needs to be replaced with the same specifications (it is recommended to choose original factory parts).

2. Leakage or excessive standby power consumption

Circuit component short circuit or functional module abnormal power consumption (such as indicator lights always on, sensors continuously working)

Turn off unnecessary functions (such as alarm sound, LED lights), let it sit for 24 hours and observe the power consumption. If it is abnormal, check whether the circuit board is leaking electricity.

VII. Special failures in extreme environments

1. Low temperature environment (winter)

Failure: The locking rod is frozen and cannot be raised or lowered, or the motor is weak

Solution: Use warm water (not hot water) to rinse off ice and snow, or use a hair dryer on a low temperature setting to dry it. Apply low-temperature lubricating grease in advance (such as -30℃ special butter).

2. Humid environment (rainy season)

Failure: Buttons malfunction, circuit board short circuit

Solution: Open the casing and wipe the water stains on the circuit board with alcohol. After drying with a hair dryer's cold air, test it. If it is still ineffective, the control board needs to be replaced.

VIII. Professional repair suggestions

Do not disassemble it unnecessarily: When dealing with core components such as circuit boards and motors, self-operation may enlarge the fault or cause electric shock. It is recommended to contact the brand after-sales service (keep the warranty card, some faults can be repaired free of charge).

Accessory compatibility: When replacing batteries, sensors, and other parts, prioritize the use of original factory parts to avoid adaptation problems due to inconsistent specifications.

Regular maintenance to prevent failures: Cleaning, lubrication, and functional testing every quarter can reduce more than 80% of sudden failures (see How to maintain the remote control parking lock? for specific maintenance methods).

Through the above troubleshooting steps, most common faults can be solved by yourself; if the problem is complex or beyond your capabilities, seeking professional help is the most reliable choice.
