What is a Key Cover?

A key cover, often referred to as a key shell or key case, is the outer part of your key. It houses the electronic board, chip, and battery but excludes the internal electronics themselves. If your key casing is damaged, there’s no need to replace the entire key – just changing the key cover can restore its durability and usability while saving you money.

When Do You Need a New Key Cover?

You might need a key cover replacement when:

  • The buttons on your key become worn out or stop responding.
  • The outer case cracks, exposing the internal electronics.
  • The key mechanism no longer functions smoothly.
  • You want to refresh the appearance of your key with a new, sturdy shell.

Instead of struggling with a faulty key, simply replace the cover and extend the lifespan of your original key!

How to Choose the Right Key Cover?

When selecting a replacement key cover, consider the following factors:

  • Button Layout: Ensure that the number of buttons and their symbols match your existing key.
  • Blade Shape: If your key includes an integrated blade, make sure the new shell accommodates it correctly.
  • Quality: A good-quality key cover ensures a snug fit, smooth functionality, and long-lasting durability.

At MR-KEY, we offer a variety of key covers designed to match your specific car model perfectly, providing both aesthetics and functionality.

  2. Open your old key case carefully.
  3. Transfer the electronic board and chip from your original key to the new key cover.

What Else Can You Change When Replacing the Key Cover?

What You Need To Know About BMW  Swirl Flaps and How To Solve The Problem With Them

What You Need To Know About BMW Swirl Flaps and How To Solve The Problem With Them

Swirl flaps are a BMW system that has been introduced to help burn the fuel mixture in the cylinder better due to the fact that diesel engines do not have throttle valves and it is not possible to adjust the air-fuel ratio. A diesel engine without vortex valves operates between a poor and a rich fuel mixture, because the only way to regulate it is through fuel injection. Design of the first generation swirl flaps that are made of made of metal. Unfortunately, swirl flaps are responsible for countless damaged engines and costly repairs due to design errors or metal fatigue. Once damaged, the cylinder sucks them in and causes great damage. This is how damaged valves damage the cylinder. Typical swirl flaps suction damage. The vortex valves are positioned in the inlet and are controlled by vacuum (DDE 4.0) or electrically (DDE5.0 / DDE6.4) by the engine ECU. Effects of malfunctioning valves: Swirl valves are stuck in open position: Deterioration of exhaust gas performance at lower speeds. Swirl valves are stuck in closed position: Approximate power loss of 10% at high engine speeds. How swirl flaps work: Performance characteristics: The vortex valves are in the closed position, at low engine speeds and small amounts of fuel injected (controlled by the ECU card). They open under the following conditions: coolant temperature <14 ° C OR * fuel quantity> 24 mg OR engine speed 2250 rpm OR inlet air temperature <-5 ° C BMW and Pierburg have decided to produce diesel engines with metal vortex valves. The speed at which the pistons in the diesel engine operate is at least 60 rpm, so a sucked vortex valve will break and cause a number of damages inside the engine. In most cases, one or more pistons are severely damaged, as a bonus you get valves, in some cases a head or turbocharger. And this combination with a BMW engine is like a cumulative jackpot 🙂 In 2004, BMW began work on the problem and improved the design, however, a number of owners reported ongoing problems in this area. The solution to this problem is by removing the vortex valves and plugging, which does not affect the performance of the engine and at the same time, you can safely pass the exhaust test. Engines: M47 (136hp VP44 fuel pump) has no valves. M47N common rail engine (including M47N / M47TU / M47TUD20) (150hp. Face lift model from 2001 -) has valves. M57 engines (M57D) (525d & 187hp. 330d) cars with manual transmission do not have valves, but those with automatic have. M57N engines (M57TUD) (525d & 330d 204hp) have vortex valves. Ruined swirl flaps: The plugs that replace the vortex valves are easy to find on the internet, but you can also find them here on our website. Typical plugs: Disassembly of vortex valves: The vortex valves can be safely dismantled and in most cases if they are removed properly no loss of power is felt. Final list of models for which vortex valves are installed: Engine: M47N/M47TU/M47TUD20 Applications: * 110 kW (148 hp) and 330 N·m (243 lb·ft) o E46 320d 2001-2005 o E83 X3 2.0d (up to end of 2006) Engine: M47TU2D20 The engine was updated again in 2004 as the M47TU2D20.

Do Car Keys Have GPS? What You Need to Know About Key Tracking

Do Car Keys Have GPS? What You Need to Know About Key Tracking

In an age where smartphones can locate us with pinpoint accuracy and lost luggage can be tracked halfway around the world, it’s easy to assume car keys are just as smart. But for many frustrated drivers, losing a car key feels like sending it into a black hole. The lack of a clear way to find them often leads to stress, wasted time, and sometimes costly replacements. So here’s the big question: Do car keys have GPS, and can they be tracked like other smart devices? This article explains the technology behind key tracking, compares GPS with Bluetooth, and offers practical ways to find lost keys in a connected world. The Truth About GPS in Car Keys While GPS technology has become common in many consumer devices, the vast majority of car keys do not include built-in GPS. Even the most modern remote key fobs, which allow for keyless entry and push-button start, generally lack the components necessary for GPS functionality. These components include a satellite GPS receiver, a data transmission module, and a sustainable power source—none of which are typically found in a key fob. The design of a car key prioritizes compactness, cost-efficiency, and low energy usage. Adding GPS would not only increase manufacturing costs but also introduce battery life challenges. That’s why most manufacturers have opted against including GPS tracking in car keys. GPS requires constant power and data transmission — something a small coin cell battery in a typical key fob can’t support." – Marcus Lee, Automotive Tech Analyst How Can Car Keys Be Tracked? Although your keys may not have GPS, there are other technologies that make it possible to track or locate them when they’re lost. These include Bluetooth trackers, crowdsourced networks, and GPS systems that track the vehicle instead of the key itself. 1. Bluetooth Trackers (Apple AirTag, Tile, Chipolo) These small, attachable gadgets can be added to your keychain and linked to a mobile app. They rely on Bluetooth to provide location data when within a certain range. If your keys are somewhere nearby—like in your home or office—these trackers can play a sound or show you their last known position on a map. The range is generally up to 120 meters (400 feet), and battery life can last up to a year, making them a practical, low-maintenance option for most users. 2. Crowdsourced Networks (Find My, Tile Network) If your Bluetooth tracker is out of range, some brands offer a smart workaround. Apple’s AirTag, for instance, uses the “Find My” network, which consists of millions of iPhones around the world. If someone with an Apple device passes near your lost keys, the location is anonymously and securely sent to your phone. This creates a global, decentralized tracking system that mimics GPS functionality without requiring satellites or cellular connections. 3. Car GPS Systems (Vehicle Only, Not the Key) Some high-end cars offer integrated GPS systems, but these track the vehicle, not the keys. Brands like Tesla, BMW, and Mercedes-Benz allow owners to locate their car through mobile apps. If your keys are left inside the car, you may be able to find them by locating the vehicle. However, once the keys are removed, they cannot be tracked unless equipped with a separate Bluetooth tracker. GPS vs Bluetooth: What’s the Difference? To better understand why GPS isn’t commonly included in car keys, it’s useful to compare the two technologies: GPS provides global, real-time tracking with high precision, but it’s power-intensive and costly. Bluetooth, while more limited in range, is ideal for small items and short distances, offering a cost-effective solution for everyday use. Global Perspectives on Key Tracking Around the world, the adoption of key tracking technologies differs based on privacy laws, tech infrastructure, and consumer behavior. In Japan and South Korea, smart home and car integration are advanced, yet GPS-enabled keys are still not the norm. In many parts of Europe, particularly in countries like Germany, Bluetooth solutions are favored due to strict data privacy regulations. In contrast, the U.S. market has embraced personal tracking devices like Apple AirTag and Tile, making them increasingly common accessories. These differences highlight how technology adoption often reflects broader cultural and legal norms, as well as the balance between convenience and privacy. Smart Tips to Keep Track of Your Keys Whether your keys have advanced tech or not, you can take simple steps to avoid losing them. Attaching a Bluetooth tracker is a great first line of defense. Keeping your keys in a consistent, designated place at home reduces the chances of misplacement. Many tracking apps also offer “left behind” alerts, which notify you if you leave your keys behind when moving out of range. It's also smart to keep a spare key somewhere safe and consider going keyless if your next car allows it. Implementing a few of these habits can save you time, frustration, and the cost of replacing a lost key. The Future of Key Tracking While car keys may not have built-in GPS, technology continues to evolve with practical alternatives. Bluetooth trackers, supported by app alerts and community networks, already provide effective ways to find lost keys. As innovation progresses, we can expect even more seamless solutions, such as Ultra Wideband (UWB) technology and Internet of Things (IoT) integrations, to become mainstream. As our tools become smarter, so must the way we use and manage them. With a little foresight and the right accessories, you'll never lose track of your keys again.
