Can a car key purchased online be paired?

[AryaLynn]

Matching the car model, brand, and displacement is necessary for pairing. Relevant instructions for using car keys are as follows: 1. Instruction one: Keys should not be placed together with items such as mobile phones and bank cards, as this may cause interference with the remote key, rendering it unusable. During use, the remote key should not be placed in direct sunlight or in damp and dark places, as these conditions can cause issues with the remote key. If the vehicle key is not used for an extended period, the battery inside the key should be removed. 2. Instruction two: When using the remote key for a motor vehicle normally, avoid contact with metal objects. Contact with metal objects may lead to the smart key being covered by metal materials, potentially causing malfunction. During bumpy conditions, metal objects may also damage the smart remote key. When using the vehicle's remote key normally, avoid throwing or tossing it around, as the internal circuitry of the remote key has weak shock resistance and may be damaged in severe collisions.
