Does the car key have a positioning function?

[FranciscoMarie]

Some car models have keys with positioning capabilities. For keys without positioning, a positioning chip can be installed in the car. Below is additional information about car keys: Key anti-loss device: You can purchase a smart key anti-loss device, which consists of a finder and a receiver that communicate via Bluetooth signals. Simply attach the receiver to the key, and when the owner cannot find the key, pressing a designated button on the finder will cause the receiver to emit a sound, allowing the owner to locate the key by following the sound. Lost car key: If a key is lost, the immediate thought is to use the spare key. After obtaining the spare key, the next step is to have a new key made, rendering the old key ineffective. However, this ineffectiveness refers to the inability to start the vehicle. Since the car door has a mechanical lock, the old key can still open the door. For safety reasons, it is advisable to replace all the car's lock cylinders. Once the lock cylinders and keys are new, there is no need to worry about the old key being able to open the door.
