This guide is designed to minimize the time required for returns and exchanges.Order Guide:A: Can this smart LCD key from your store replace my original car key to control my vehicle?Three conditions must be met: 1. Your car must have come equipped with a push-button start feature from the factory to be compatible with the smart LCD key. This must not be a aftermarket-installed keyless start system.2. You must disassemble the original car key, remove its circuit board, and solder it to the LCD key’s wiring harness. The soldering must be error-free and correct to ensure the LCD key can perform the functions of the original key’s circuit board.3. The LCD key merely serves to give the key a new look; it relies on the functionality of the original key’s circuit board. Therefore, before soldering, you must use the original key’s circuit board to lock and unlock the car to verify that the circuit board is functioning properly. If the original key’s circuit board is faulty, soldering it to the LCD key will not work.B: How do I solder the original key’s circuit board to the smart LCD key’s wiring harness?1. I do not recommend that users attempt soldering themselves. Instead, take it to a mobile phone repair shop and have a professional perform the soldering using proper tools.2. When soldering, please read the instructions carefully. The manual explains the soldering process; do not reverse the positive and negative terminals, as this will render the device inoperable. Many users lack soldering experience, and using soldering tools on their own can easily lead to a shaky hand, potentially damaging the original key’s circuit board during the process. Therefore, we strongly recommend taking it to a mobile phone repair shop and having a professional perform the soldering; please do not attempt this yourself.3. Before removing the circuit board from the original key for soldering, you must test it to ensure the circuit board can properly control the car—including locking and unlocking it—and verify that all functions are working before proceeding with the soldering. Many customers bring in faulty original key circuit boards for soldering. A smart LCD key merely changes the appearance; its functionality depends entirely on the original key’s circuit board, which is the core component controlling the vehicle. If the circuit board is faulty, successful soldering will be ineffective.C: Can a smart LCD key activate all functions of the original key’s circuit board?The LCD key has only three wiring harnesses, meaning it can only activate the three functions on the circuit board. Any additional functions on the circuit board cannot be activated because they cannot be soldered. You will need to make a choice.D: Can the smart LCD key change the wallpaper on the screen or customize the car logo?None of the smart LCD keys have these features; the wallpaper is fixed, and the car logo cannot be customized.E: My car has a push-button start feature, but my original key does not. Can the smart LCD key modify this function to give my original key push-button start capability?The push-button start feature is a method of starting the car without inserting a traditional key. Simply carry the original key into the vehicle, and the car will detect it; pressing the push-button start button will then start the engine. Therefore, the push-button start function is a feature of the car itself; it acts as a switch within the vehicle. When we say a car key “does not have a push-button start function,” it means that while some car brands’ keys have a remote start function, pressing the remote start button on the key triggers the push-button start switch to activate the engine. Your original car key must already have the remote start function. You can only use our LCD key to customize the appearance; it is not possible to gain the remote start function through the LCD key itself.Q: How do I change the text on the smart LCD key to my local language?Swipe up to unlock the screen - Swipe right to enter Settings - Go to Settings and find the Language option - Tap to select your desired language.G: Power-On IssuesWhen you first receive the LCD key, do not turn it on immediately. You must first charge the LCD key for 24 hours and wait until the battery is fully charged before turning it on. This ensures the product will not experience power-on failures.H: Charging Cable Restrictions1. Do not use fast-charging cables. The LCD key uses relatively outdated circuit technology and does not support fast-charging cables. Using such cables may damage the internal circuit board, rendering the product inoperable.2. Please note that the LCD key must only be used with the original cable provided with the product. Never use other cables to avoid damaging the product.
