Every vehicle comes with an anti-theft code configured by the manufacturer. The owner needs to provide the vehicle license and identity information to the 4S shop. The 4S shop can retrieve the vehicle's anti-theft code based on the provided information and configure a new key. Additionally, they can erase the data of the lost key, rendering it invalid and unable to start the vehicle.

I've encountered this before. Last week, my neighbor lost their Wuling car key and was in a panic. Going to the 4S store is the safest option—bring the vehicle registration certificate, ID card, and driver's license. The store will retrieve the original factory data to make a new key, but it's not cheap; a key with a chip can cost around 400-500 yuan. If you're on a budget, local car key shops are more cost-effective. They can program a new key by reading the vehicle's computer data, cutting the price in half, but make sure to choose a qualified shop. If you can't find a spare key, it's advisable to also replace the door lock and ignition lock cylinder, totaling around 700-800 yuan, so anyone who finds the old key can't open the door. Wuling mechanical keys are easy to replace, but newer models with anti-theft chips require professional handling—don’t trust roadside stalls.

As an experienced mechanic, I've handled dozens of cases involving lost Wuling keys. The first principle is to check if the spare key is still available. If there's a spare, simply take it to a professional shop for duplication - it takes 20 minutes and costs about 50 yuan. If all keys are completely lost, follow these three steps: First, go to the local police station to obtain a lost key certificate for the vehicle. Second, contact SAIC-GM-Wuling customer service to retrieve the anti-theft password using the VIN. Third, take the password to a 4S store to program a new key, with total costs around 400 yuan. Special reminder: always synchronize the modification of the anti-theft system, otherwise the old key can still start the car. Avoid risky shortcuts like asking repair shops to remove the steering wheel cover to bypass the anti-theft module - it's not worth trying.

Last time my wife lost the Wuling car key at the vegetable market. I immediately went to the auto parts market and found a professional shop. The boss used an OBD scanner to connect to the interface under the steering wheel, directly read the engine anti-theft password, and generated a new key. It cost 230 yuan and took 40 minutes to get a folding remote key on the spot. Make sure the new key can unlock the door and start the engine—I once encountered an aftermarket key that could unlock the door but failed to start the car. For older models without anti-theft chips, it’s even simpler—just copy the key shape using a machine. I recommend changing the car locks while getting a new key; the full set costs just over 300 yuan for peace of mind.
