The question of how the room frame opens often arises in motorists in two situations: when it is urgent to remove the license plate for replacement or re-registration, and when you just need to wash the car under pressure. Modern designs are often equipped with complex protection mechanisms, which are not always clear how to activate the first time. Understanding the principle of operation of locks and latches allows you to avoid damage to both the holder and the body of the machine.
Many drivers mistakenly believe that all mounts are the same and require only a standard set of tools, but this is not the case. There are models with secret screws, anti-vandal versions with secretions and simple options on plastic latches. Wrong effort. When trying to open the lock can lead to breakage of plastic fixtures or even damage to the paint coating of the bumper. That is why it is important to determine in advance the type of design you are dealing with.
In this article, we will discuss in detail the different types of fasteners, the algorithms of actions for their safe dismantling and the nuances that are silent manufacturers of accessories. You will learn which tools are really needed and which can be harmful, and you will get clear instructions for different scenarios.
Types of anchorages and fixing mechanisms
The first thing that the owner of the car encounters when installing or removing a number is the variety of fixation mechanisms. Standard framework Most often, four holes under bolts are used, closed with decorative plugs. However, the market is saturated with more complex solutions designed to protect the license plate from theft or spontaneous unscrewing at high speed. Understanding the type of attachment is 90% of the success in how the room frame opens without damage.
One common variation is the system with secret screws. In such designs, the bolt caps are hidden under the front panel or a special pad, which opens only when the key is turned or the hidden pin is pressed. This creates the illusion of monolithic design, but in fact requires careful handling. Mechanical latches, in turn, are often found in budget models and are simple plastic clips that easily break when overheated in the sun or severe frost.
⚠️ Attention: Attempting to open the frame with secret screws by brute force (driver digging without understanding the mechanism) is almost guaranteed to lead to scratches on the license plate and chips on the bumper.
There are also combined systems, where part of the mounts is standard, and part is additional protection. For example, the upper bolts can be normal, and the lower ones - closed with an anti-vandal cover. In such cases, the algorithm of actions becomes more complex, requiring consistent execution of operations.
Necessary tools for dismantling
Before proceeding to direct removal, it is necessary to prepare the right tools. The use of inappropriate items is the main reason why inexperienced drivers do not manage to neatly solve the problem, as the room frame opens. A standard set should include a set of screwdrivers with various slits, including cross and small flat sized ones. Particular attention should be paid to the quality of the screwdriver sting: it should sit tightly in the screw screw screw screw so as not to lick the edges.
To work with plastic elements and stubs, special removers or plastic shoulder blades are often required. Metal tools are not recommended here, as the risk of damage to soft plastic or paint is too great. If we are talking about rusted bolts that could sour over the years of operation, an indispensable assistant will be penetrating lubricant, such as WD-40 Or its analogues. Processing the thread 10-15 minutes before the start of work will greatly simplify the process.
In some cases, especially when working with anti-vandal structures, a specific tool may be required, which comes complete with a frame. These can be special hexagon keys of unusual shape or magnetic detachers. Losing such a key makes the number withdrawal a serious problem requiring drilling of the mounts.
| Tool. | Appointment | Risks in misuse |
|---|---|---|
| Cross screwdriver (PH1, PH2) | Twisting the main bolts | Slimming of the screw faces |
| Plastic spatula | Smashing stubs and clips | Minimum (plastic scratches) |
| Penetrating lubricant | Ruining of rust in carving | Resistance to rubber seals |
| Flat-deaders | Removal of broken bolts | Frame and bumper damage |
☑️ Tool preparation
Algorithm for Removing Standard Framework Construction
Consider the classic scenario that occurs on most cars. In this case, the frame is held on four bolts, the caps of which are closed with decorative round or square caps. The process begins with a visual inspection: it is necessary to determine whether the plugs are removable or they are part of the mechanism. In 95% of cases, these elements are simply inserted into the holes and fixed by friction or small antennae.
To remove the plugs, carefully tuck their edge with a plastic spatula or a thin knife with a wide blade, trying not to damage the surface of the license plate. You need to act confidently, but without jerks. After the decorative elements are removed, you will see the slivers of bolts. Here it is important to choose a screwdriver exactly the size: too small will turn inside and damage the metal, and too large will not enter the hole. Unscrew the bolts counterclockwise by holding the frame with your second hand so it doesn't fall and scratch the bumper.
⚠️ Warning: When you unscrew the bolts, the frame can suddenly free up and hit the body of the car. Always hold the design with your hand or ask an assistant to insure you.
If the bolts do not twist due to corrosion, do not apply excessive force immediately. Pour the thread with penetrating lubricant profusely and wait 10-15 minutes. Then try to gently rip off the bolt, slightly tapping the screwdriver handle. Often the rust is broken down and the fastener begins to unscrew. If the bolt hat is still broken, you will have to use an extractor or drill the rest, which requires more serious skills and tools.
What to do if the bolt is rusted dead?
If the lubricant did not help, you can try to warm the bolt head with a building hair dryer (carefully so as not to melt the plastic frame). The thermal expansion of the metal can loosen the grip of rust. Also effective method of "swinging": try to twist the bolt a little, then slightly twist, gradually increasing the amplitude.
Features of antivandal frames and secretions
The question of how the room frame opens becomes especially relevant if the car has anti-vandal protection. Such systems are designed specifically to prevent license plate theft, which is unfortunately common. The design of such frames usually involves the presence of a hidden locking mechanism. Bolts can be closed with a rotary washer, which opens only when combining labels or using a special hexagon key of a non-standard shape.
Often, these frames have "floating" elements. For example, the outer decorative part may move relative to the inner part, and access to the fastener is only open in a certain position. This mechanism must be found to dismantle. Sometimes it is enough to press the finger on the hidden lever under the lower shelf of the frame, sometimes it is necessary to move the upper part to the side. Secret keyIf it came in the kit, it usually has a unique configuration of faces that cannot be matched by a standard set of tools.
In case of loss of the key to the anti-vandal frame, the situation is complicated. Some drivers resort to radical measures, for example, drilling the central locking element or carefully parsing the frame at the seam (if it is glued or prefabricated). However, this requires jewelry precision. If you are not confident in your abilities, it is better to contact a specialized service, where you have experience with such systems and tools for a gentle autopsy.
Take a picture of the key to the secret frame and save the photo in the cloud. If the key is lost, any turner will be able to make a duplicate in 10 minutes, which will save you time and nerves.
Dismantling of frames on latches and clips
Modern cars, especially European and Korean production, are often equipped with factory or close to them frames that are mounted not on bolts, but on plastic latches or clips. This simplifies installation and gives aesthetics, but creates difficulties when removing. The mechanism here works on the principle of the fixator: you need to simultaneously press on the central part of the clip and pull it out, or dilute the antennae on the sides.
The main problem with these mounts is the fragility of plastic. Over time, under the influence of ultraviolet light and temperature changes, the plastic becomes rigid and brittle. A sharp movement can lead to the fact that the clip breaks inside the hole in the bumper, and extracting it from there will be extremely difficult. Therefore, before starting work, it is recommended to warm up the attachment area (for example, warm air from a hair dryer or just leaving in the sun) to make the plastic more elastic.
The removal technique is simple: tuck the edge of the clips with a flat screwdriver, lift the central hat by 2-3 millimeters, and then pull the entire structure out with your fingers or pliers. If the frame is held on the rotary latches (as in some models) BMW or Audi), they must be rotated 90 degrees, after which the frame is free to remove. Do not use force: if the mechanism does not go, then you did not find the right angle or did not fully unlock the lock.
Plastic in the cold becomes as fragile as glass. Never try to remove the frame on the latches at a temperature below -5 ° C without prior warming up, otherwise the breakage of the clip is inevitable.
Problems with corrosion and jamming
One of the most common reasons why you can’t get a room is corrosion. Water, salt and reagents from the roads get inside the fasteners and turn the steel thread into a monolith with an aluminum body or plastic frame. In such cases, standard methods do not work. If you feel that the bolt does not turn, do not increase the force indefinitely - you risk breaking the bolt head.
An effective method of combating is the use of chemistry. of the mentioned penetrating lubricants, special rust solvents can be used. Apply the product to the thread and give it time to penetrate the microcracks. Sometimes the method of "heat-cooling" helps: short-term heating of the bolt and subsequent sharp cooling can destroy the oxides. However, with heating, you need to be careful not to damage the paint coating of the bumper.
If the bolt is still torn or broken, you will have to use an extractor (twisting). It's a reverse-rotted tool that screws into a drilled hole in the bolt's remnants and twists it out. The process is time-consuming and requires care so as not to go away with a drill to the side and not damage the body of the car. In extreme cases, when the number needs to be removed urgently, and there is no time for fuss, you can carefully drill the bolt hat, remove the frame, and then drill the rest of the leg.
Frequently Asked Questions (FAQ)
Can I remove the room frame without damaging the license plate?
Yes, it is possible if you act carefully. The main thing is not to use metal tools in the immediate vicinity of the surface of the room, so as not to leave scratches. Use plastic blades and properly selected screwdrivers. If the frame is glued to the number (which happens in cheap models), it is better to replace it along with the number or gently cut with a sharp knife, heated with a glue dryer.
What to do if the key to the anti-vandal frame is lost?
If the key is lost, there are few options. You can try to find a similar key (for example, from furniture fittings), if the mechanism is simple. In difficult cases, you will have to disassemble the frame, possibly with partial destruction of plastic elements, or drill lock bolts. It is best to make a duplicate key or take a picture of its profile.
Do I need to remove the frame for washing the car?
Modern frames, as a rule, do not require removal for washing. However, if the frame is not tightly attached or has design features, dirt and moisture can accumulate under it, causing corrosion. Periodic removal (once a year) for cleaning the space under the number is useful for the safety of the body, but for each wash it is not necessary to do this.
How to prevent the swelling of the bolts in the future?
When installing a new number or frame, be sure to treat the bolt thread with graphite lubricant or copper lubricant. This will create a protective layer that will prevent the metal from coming into direct contact with moisture and oxygen, and next time you can unscrew the bolts without any problems even after a few years.
