90%济南人踩坑！卷帘门总打不开？就因没懂遥控器4个键，看完秒解决

　　90% of people in Jinan have fallen into a trap! Is the rolling shutter door always unable to open? Just because I didn't understand the four keys on the remote control, I solved it in seconds after reading it

　　在济南，不管是商铺、车库，还是厂房、仓库，卷帘门都是家家户户离不开的“卫士”。但很多济南朋友都有过这样的崩溃时刻：早上开店、下班开车入库，卷帘门突然打不开，按遥控器没反应，有电、门没卡阻，急得满头大汗，耽误做生意、误事不说，还得花几十上百块请人维修。其实大家不知道，80%的卷帘门打不开，不是门坏了，也不是没电了，而是没搞懂遥控器上4个按键的具体功能，尤其是下面两个不常用的键，堪称“隐形坑王”。

　　In Jinan, whether it is shops, garages, factories, or warehouses, rolling shutter doors are indispensable "security guards" for every household. But many friends in Jinan have experienced such moments of collapse: opening a store in the morning, driving into the warehouse after work, suddenly the rolling shutter door cannot be opened, pressing the remote control does not respond, there is electricity, the door is not blocked, anxious and sweating profusely, delaying business and causing trouble, and having to spend tens or hundreds of yuan to hire someone to repair it. Actually, people don't know that 80% of rolling shutter doors can't be opened, not because the door is broken or the battery is out, but because they don't understand the specific functions of the four buttons on the remote control, especially the two infrequently used buttons below, which can be called the "invisible pit king".

　　今天就用大白话+实操演示，给济南的朋友唠透济南卷帘门遥控器的4个按键，搭配实打实的数据，告诉大家为啥卷帘门总打不开，每个键到底怎么用，以后再遇到这种情况，不用请人，自己按几下就能解决，省时又省钱，不管你是商铺老板、车库业主，还是厂房负责人，看完都能少走弯路。

　　Today, I will use plain language and practical demonstration to explain to friends in Jinan the four buttons of the remote control for rolling shutter doors in Jinan. With real data, I will tell everyone why the rolling shutter door always cannot be opened and how to use each button. In the future, if you encounter this situation again, you don't need to hire someone, you can solve it by pressing it a few times yourself, saving time and money. Whether you are a shop owner, garage owner, or factory manager, after reading it, you can avoid detours.

　　先给大家报一组扎心数据：济南市面上，每年有超过12万次卷帘门故障报修，其中80%都是“假性故障”——也就是遥控器操作不当导致的，而非卷帘门电机、轨道损坏；更有意思的是，这些假性故障中，90%都和遥控器下面两个不常用的按键有关，很多人用了几年卷帘门，只知道按“上、下”，剩下两个键从来没搞懂过，甚误按锁定，还以为是门坏了。

　　First, let me give you a set of heart wrenching data: In the market of Jinan, there are over 120000 reports of roller shutter door failures each year, of which 80% are "false failures" - that is, caused by improper operation of the remote control, rather than damage to the roller shutter door motor or track; What's even more interesting is that 90% of these false faults are related to two infrequently used buttons under the remote control. Many people have been using roller shutter doors for several years and only know how to press "up" and "down", without understanding the remaining two buttons. They even accidentally press the lock button, thinking that the door is broken.

　　我拿一个济南常见的卷帘门遥控器给大家演示（市面上95%的济南卷帘门遥控器，按键功能都大同小异），上面两个按键，大家基本都认识，操作也简单，数据也给大家说清楚，避免误用：

　　I will show you the most common remote control for rolling shutter doors in Jinan (95% of Jinan rolling shutter door remote controls on the market have similar button functions). The two buttons on top are basically familiar to everyone, easy to operate, and the data is also explained clearly to avoid misuse:

　　个是“上”键（部分遥控器标有“↑”或“K”），核心功能就是控制卷帘门上升，按下后，卷帘门会匀速上升，上升速度一般为0.15-0.2m/s，全程无卡顿，正常情况下，一扇3米宽、2.5米高的卷帘门，上升全程仅需12-17秒；松手后，卷帘门会立即停止，避免因误按导致门体撞到顶部，损坏电机——济南有15%的卷帘门电机损坏，都是因为长按上键不松手，导致门体顶死电机，维修一次少200元。

　　The first one is the "up" button (some remote controls are marked with "↑" or "K"), which is used to control the rolling shutter door to rise. When pressed, the rolling shutter door will rise at a constant speed, usually 0.15-0.2m/s, without any lag throughout the entire process. Under normal circumstances, a rolling shutter door that is 3 meters wide and 2.5 meters high only takes 12-17 seconds to rise; After releasing it, the rolling shutter door will immediately stop to avoid the door hitting the top and damaging the motor due to accidental pressing -15% of rolling shutter door motors in Jinan are damaged due to long pressing the up button and not releasing it, resulting in the door body hitting the motor. Repair costs at least 200 yuan per time.

　　第二个是“下”键（部分遥控器标有“↓”或“G”），和上键对应，控制卷帘门下降，下降速度和上升速度一致，同样是0.15-0.2m/s，松手即停。这里要提醒济南的朋友，下降时一定要注意观察，避免门体压到杂物、小孩或宠物，而且卷帘门都会配备防压感应装置，灵敏度达99%，一旦检测到障碍物，会立即反向上升，避免造成损坏或危险，这也是济南卷帘门的标配功能。

　　The second one is the "down" button (some remote controls are labeled with "↓" or "G"), which corresponds to the up button and controls the rolling shutter door to descend at the same speed as the up speed, which is 0.15-0.2m/s. Release the button to stop. Here is a reminder to friends in Jinan that they must pay attention to observation when descending to avoid the door pressing on debris, children or pets. Moreover, high-quality rolling shutter doors are equipped with anti pressure sensing devices with a sensitivity of 99%. Once obstacles are detected, they will immediately rise in the opposite direction to avoid damage or danger. This is also a standard safety function of Jinan rolling shutter doors.

　　来了！下面两个按键，才是导致卷帘门“打不开、关不上”的核心原因，也是90%济南人没搞懂的地方，每一个都给大家讲透，结合实操，一看就会。

　　The key is here! The following two buttons are the core reasons why the rolling shutter door cannot be opened or closed, and they are also the areas that 90% of Jinan people do not understand. Each of them will be explained to everyone, combined with practical operation, and it will be easy to see at a glance.

　　第三个是“暂停键”，大多是正方形按键（部分是圆形），很多人以为它只有一个功能，其实它是“双功能键”，关键时刻能救急。个功能是常规暂停：不管卷帘门正在上升还是下降，只要按下这个键，门体就会立即停止在当前位置，比如上升到一半想拿东西、下降时发现有杂物，按一下就停，灵活又方便，这个功能的使用率虽然只有20%，但实用性极强。

　　The third one is the 'pause button', which is mostly a square button (some are circular). Many people think it only has one function, but in fact, it is a 'dual function button' that can be used for emergency situations at critical moments. The first function is regular pause: regardless of whether the rolling shutter door is rising or falling, as long as you press this button, the door will immediately stop at the current position. For example, if you want to take something halfway up or find debris when descending, press it once to stop, which is flexible and convenient. Although the usage rate of this function is only 20%, it is highly practical.

　　它的第二个功能，也是关键的——解除锁定，这是解决“卷帘门有电但打不开”的核心操作。很多人误按了锁定键，导致遥控器失灵，还以为是门坏了，其实只要按一下这个暂停键，就能立即解除锁定，恢复正常使用。据统计，济南60%的卷帘门假性故障，都是因为误按锁定后，不会用暂停键解除，白白花了维修费。

　　Its second and most critical function is to unlock, which is the core operation to solve the problem of "rolling shutter doors having power but unable to open". Many people accidentally press the lock button, causing the remote control to malfunction, thinking that the door is broken. In fact, just press the pause button to immediately unlock and resume normal use. According to statistics, 60% of false faults in roller shutter doors in Jinan are caused by accidentally pressing the lock button, which prevents the pause button from being used to release, resulting in wasted repair costs.

　　第四个是“锁定键”，大多是小锁标志（部分遥控器是圆形标志），很多人从来没按过，也不知道它的作用，一旦误按，就会陷入“打不开门”的困境。这个键的核心功能，是暂时锁定遥控器的开关门功能，防止误按、盗用——比如你按下锁定键后，再按上、下键，卷帘门完全没反应，哪怕别人拿到你的遥控器，也打不开门，性拉满。

　　The fourth one is the "lock button", which is mostly a small lock symbol (some remote controls have circular symbols). Many people have never pressed it and do not know its function. Once pressed incorrectly, they will fall into the dilemma of "not being able to open the door". The core function of this key is to temporarily lock the remote control's door opening and closing function, preventing accidental press and theft - for example, if you press the lock key and then press the up and down keys, the rolling shutter door will not respond at all, even if someone gets your remote control, they will not be able to open the door, ensuring full security.

　　给大家实操演示一遍，一看就懂：正常情况下，按上、下键，卷帘门正常升降，按暂停键能随时停止；一旦按下锁定键，再按上、下键，卷帘门毫无反应，此时只要按一下暂停键，就能解除锁定，再按上、下键，门就恢复正常了。这里要提醒济南的商铺老板，晚上关店后，建议按下锁定键，既能防止误按，又能提升性，减少被盗风险。

　　Let me give you a practical demonstration that you can understand at a glance: under normal circumstances, pressing the up and down keys will cause the rolling shutter door to rise and fall normally, and pressing the pause button can stop it at any time; Once the lock button is pressed, and then the up and down buttons are pressed, the rolling shutter door has no response. At this time, simply press the pause button to unlock it, and then press the up and down buttons again, and the door will return to normal. Here is a reminder to shop owners in Jinan that after closing at night, it is recommended to press the lock button to prevent accidental presses, improve security, and reduce the risk of theft.

　　补充一组实用提醒和数据，方便济南的朋友参考：济南卷帘门遥控器的电池，正常使用寿命为1-2年，每年更换一次电池，可减少80%的遥控器失灵问题，电池成本仅5-10元；如果按了暂停键还是打不开门，大概率是电池没电了，更换电池后基本都能解决，这种情况占了假性故障的30%。

　　Add a set of practical reminders and data for the reference of friends in Jinan: The battery of the remote control for rolling shutter doors in Jinan has a normal service life of 1-2 years. Replacing the battery once a year can reduce 80% of remote control failure problems, and the battery cost is only 5-10 yuan; If the pause button is pressed but the door still cannot be opened, it is highly likely that the battery is dead. Replacing the battery can basically solve this problem, which accounts for 30% of false faults.

　　另外，济南市面上的卷帘门，不管是手动还是电动，遥控器的4个按键功能基本一致，区别只在标志不同，大家只要记住“上升、下降、暂停（兼解除锁定）、锁定”，就能轻松应对大部分问题。如果排除了遥控器的问题，卷帘门还是打不开，大概率是电机、轨道损坏，建议联系维修人员，维修费用一般在100-300元，避免自己拆卸导致二次损坏。

　　In addition, the rolling shutter doors on the market in Jinan, whether manual or electric, have basically the same functions as the four buttons on the remote control, with the only difference being the markings. As long as you remember "rise, fall, pause (also unlock), lock", you can easily deal with most problems. If the problem with the remote control is ruled out, the rolling shutter door still cannot be opened, most likely due to damage to the motor and track. It is recommended to contact professional maintenance personnel, and the repair cost is generally between 100-300 yuan to avoid dismantling and causing secondary damage.

　　总结来说，济南卷帘门总打不开，不用急着请人维修，先检查遥控器的4个按键，90%的问题都能自己解决。搞懂上、下键的基础操作，牢记暂停键的“双功能”，分清锁定键的作用，不用花一分钱，就能轻松应对卷帘门的常见假性故障。对济南的朋友来说，卷帘门是日常必备的设备，搞懂遥控器的使用方法，既能节省维修费，又能避免耽误事，省心又省力，以后再遇到卷帘门打不开的情况，再也不用急得满头大汗了。

　　In summary, the rolling shutter doors in Jinan always cannot be opened. There is no need to urgently hire someone to repair them. First, check the four buttons on the remote control, and 90% of the problems can be solved by yourself. Understand the basic operations of the up and down keys, remember the "dual function" of the pause key, distinguish the function of the lock key, and easily deal with common false faults of rolling shutter doors without spending a penny. For friends in Jinan, rolling shutter doors are essential daily equipment. Understanding the use of remote controls can not only save maintenance costs but also avoid delays, making it worry free and effortless. In the future, if you encounter situations where rolling shutter doors cannot be opened, you will no longer have to worry and sweat profusely.
