If the car key strap chip is lost, the first thing you need to do is contact the car manufacturer or dealer and apply for a new key. In the process of waiting for a new key, you can consider using a spare key, if there is no spare key, you can use the car door lock for temporary unlock.
However, it should be noted that after using the temporary unlock, contact the manufacturer or dealer as soon as possible to apply for a new key, so as not to cause unnecessary trouble and economic losses. At the same time, when using the car door lock to unlock, you need to ensure your own safety and avoid staying in an unfamiliar environment for too long.
If you lose your car key with a chip, first you need to contact your car manufacturer or your local auto repair shop to find out if you can reprogram a new key. You may need to provide the vehicle's license plate number and VIN number for verification.
If you have replicas of keys, you can use them to open the doors, but you may need to reprogram them as recommended by the car manufacturer to make sure they match your vehicle.
Most importantly, don't leave your car unlocked to avoid theft.
