You can leave the key at the repair shop for paint touch-up, but you need to take photos of the car's dashboard information with your and remove any valuables from the vehicle. Below is relevant information about car maintenance: Introduction to Car Maintenance: Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the vehicle, also known as car servicing. Scope of Car Maintenance: Modern car maintenance mainly includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, and other maintenance areas.

















Actually, most repair shops will ask you to leave the keys when doing paint touch-ups, as the car needs to be driven into the paint booth for work, and may need to move the car or mix paint colors. However, before leaving the keys, it's best to inspect all scratches on the car in person, take photos to record the mileage, and remove valuables like fuel cards and dashcams. Last time I had a paint touch-up, the technician took the car to wash it, and later I found oily handprints on the steering wheel. So, when picking up the car, make sure to check the paint color match and cleanliness. Reputable shops will have you sign a handover form. Nowadays, some chain stores even allow you to track real-time progress via an app, which is quite convenient.

Our master mechanic has been repairing cars for over 30 years, and leaving keys for paint touch-ups is very common. The key is whether the repair shop is reputable: check if the workshop has surveillance cameras and if keys are managed by designated personnel. Last month, my son-in-law had a bad experience with a paint touch-up—he didn't pay attention when leaving the car and later found two packs of cigarettes missing from the storage compartment when picking it up. I recommend supervising them as they lock the steering wheel and, ideally, assigning a dedicated service advisor to oversee the entire process. For dark-colored cars, it's especially important to instruct them not to mix polishing waxes—last time, my black car was treated with wax meant for light-colored cars, resulting in swirl marks all over under sunlight.

Nowadays, young people prefer convenience when it comes to car repairs. I've noticed many simply toss their keys at the front desk and leave. Actually, paint touch-ups involving metalwork and sanding take three to five days. When leaving your keys, remember to remove the ETC device to avoid accidental highway toll charges. Also, those who've modified their car infotainment systems should be reminded not to disconnect the power to avoid resetting—my friend's aftermarket CarPlay module got completely reset last time during a power cut. When picking up your car, don't just check the paint; pop the hood to ensure the terminals are tightened properly. Once, an apprentice forgot to tighten the screws, leaving me stranded halfway.

From a safety perspective, it's essential to verify the repair shop's qualifications before handing over your keys. Check if their key cabinet has dual-person dual-lock security and whether surveillance covers the parking area. Last time when I got my car repainted, a technician accidentally revealed that some shops might use customers' cars as company vehicles. Special reminder for owners who've modified their cars with keyless start systems: just leave the spare mechanical key at the shop for repainting, and take the smart key with you to prevent signal replication. Additionally, for cars with color change wraps, pay extra attention to check for edge bubbling. I've experienced situations where the wrap edges lifted after repainting.

Last week, I just picked up my car from the 4S shop after a paint touch-up, and the process was very standardized: Upon delivery, I signed a confirmation form that included the remaining fuel level, and the keys were sealed in a numbered magnetic-lock bag. The technician reminded me that for electric cars like , the sentry mode should be turned off; otherwise, the strong light in the paint booth could drain the battery. Here's the key point: For pearl paint, it's best to inspect the car on a cloudy day. Last time, I checked it on a sunny day and didn't notice any color difference, but on a rainy day, the hood clearly appeared grayish. It's recommended to bring a flashlight to check for orange peel texture and also feel the door handles for any overspray particles—these details significantly affect the overall quality.
