Key maintenance methods: Avoid frequently placing it together with metal objects; Do not store the spare key in the car door; Prevent the smart key from falling or being impacted; Keep the smart key away from high-temperature environments or contact with liquids; Do not place the key near electronic devices.
The car key I used before had a remote control range of about 30 to 100 meters, but this thing can be quite variable. You see, sometimes in an open parking lot, it can easily lock the car from a distance; but in underground garages or places crowded with parked cars, the signal range can shrink by half, maybe down to just a dozen meters. It mainly depends on the key's battery—when the battery is weak, the range shortens significantly. Also, any metal obstacles around, like walls or big trees blocking the signal, can cause interruptions. I once experienced heavy rain, and the signal got even weaker, forcing me to run to the car in the rain to press the button. To ensure a long enough range, remember to replace the battery regularly and avoid using it near sources of interference, like cell towers. Occasionally, test it by slowly walking away from the car and pressing the button to see where it stops working—that’ll give you the actual range. In short, knowing these details can save you a lot of trouble and ensure convenient car use.
