What to Do If the Car Key Code Strip Is Lost?
4 Answers
If the car key code strip is lost, you can first use the car's spare key, and then return the car key directly to the car manufacturer to have a new key made. Generally, when purchasing a car, it comes with two keys: one for regular use and one as a spare, both of which are identical. The barcode on the key does not affect the car; what matters is the car key itself. Losing the car key can be very troublesome. It is essential not to keep the spare key inside the car, as it will not be useful if the car is locked. If the car is far from the spare key, the only option is to call a professional locksmith to unlock the car.
That day when I lost the password slip for my Volkswagen car key, I was really panicked! I rushed to the 4S dealership, and the staff asked me to provide the Vehicle Identification Number (VIN), usually found in the corner of the windshield or in the owner's manual. After verifying my identity, they directly retrieved a new password from the system and helped me get a new key. The whole process was quite fast and didn’t cost much. The key is not to try random attempts yourself—if the anti-theft system is triggered, it could be troublesome. Afterward, I learned my lesson: I wrote down the VIN in my phone’s notes and always remind myself not to misplace the password slip. Losing it poses the biggest risk that someone could use it to illegally duplicate a key, threatening the car’s security. Now, I always keep a spare key in the car, so I won’t panic if anything gets lost.
As a frequent car repairer, losing the key code strip is quite common—it's the password for making new keys. I suggest you immediately check the owner's manual for the Vehicle Identification Number (VIN), usually found under the windshield or on the insurance documents. Then contact the brand's customer service or a local dealership, provide proof of identity, and they'll issue a new code so you can program a new key at a professional shop. Don't attempt to tamper with the wiring yourself to avoid locking the anti-theft system and incurring extra costs. Always store the code strip properly, avoiding damp or high-temperature environments. Additionally, modern car keys usually have anti-theft chips, making programming more complex—it's easier to find a trusted technician for this task.
When I lost the key code slip for my Honda, I immediately called the 4S store customer service. After providing the license plate and VIN (that identification number on the car), they gave me a new code in just ten minutes—super easy! Don’t struggle on your own; getting keys professionally duplicated is the fastest solution. Nowadays, many new cars support key management via mobile apps, like Toyota’s remote control, which can minimize such hassles. Always remember to back up your VIN on your phone so you can handle it directly if lost, saving time and hassle.
