Where to Get a Replacement Car Key?
2 Answers
There are generally two methods to replace a car key: one is to go directly to a car 4S store for replacement, and the other is to go to an auto parts market for replacement. The following is a related introduction about car keys: 1. Main functions: In addition to controlling the door switch, car keys can also control the window and trunk switches. 2. Working principle: When the owner presses the button on the key, the key emits a signal. The signal contains corresponding command information. The car's antenna receives the radio wave signal, and after authentication by the body control module (BCM), the actuator performs the unlock/lock action.
A broken car key is indeed a headache. I encountered this issue last time when my key remote stopped working. At first, I thought it was a battery problem, but later found out the chip was damaged. You can get a new key at a 4S dealership—they offer professional service, but it's expensive, possibly costing several hundred yuan. Alternatively, you can visit a professional car key shop, which handles various car models, including programming smart keys. Roadside stalls are cheaper and can get it done in minutes, but the quality isn’t guaranteed. I also suggest checking if it just needs a battery replacement or contact point cleaning before spending money on a new key. For older car keys, you might even DIY—buy a new key blank online and have it programmed. In short, costs vary greatly depending on the key type and car model. Remember to test the new key multiple times before leaving. Also, keeping a spare key is crucial—losing it would be even more troublesome. When getting a new key, it's best to bring your car along for programming and testing.
