2 Answers
Here is the method for replacing the complete car lock for BYD L3: 1. Clear the original key code. 2. Register the new key code. 3. Perform remote matching to complete the replacement. Below are daily precautions for car key usage: 1. Every time you exit the car, even if it's just for a few minutes, turn off the engine, remove the key, and lock the car to prevent giving thieves an opportunity. 2. Car keys should be kept waterproof, protected from severe vibrations, and kept away from magnetic interference. If the key is damaged, it also needs to be replaced. 3. Keep the spare key and the main key separate. Do not lock the spare key inside the car, especially for vehicles with one-button start or engine immobilizers, as the spare key can fully start the engine. 4. If the key is lost and cannot be matched in time, do not leave valuables in the car. Additionally, consult your insurance company about the details of compensation for vehicle theft to ensure you have the necessary evidence in case the vehicle is stolen.
I once replaced the entire lock set on my BYD L3, which was quite an interesting experience. First, you need to purchase an original or compatible lock kit, including door locks, trunk lock, and ignition lock. Prepare the necessary tools: Phillips screwdriver, hex key, plastic pry bar, and gloves to prevent scratches. When removing interior panels, gently pry open the clips—don’t force them and damage the plastic. Then locate the screws of the old locks, loosen and remove them, and install the new locks in the correct position. If it’s an electronic central locking system, you’ll need a diagnostic tool to program and match the keys, otherwise the car won’t start. The whole process takes about half a day, and you should test each lock to ensure smooth operation. Remember to disconnect the car battery first to avoid short circuits and wire damage. It’s not too difficult, but beginners should watch online BYD tutorials for details to avoid costly mistakes.
