“Chipped, or Transponder, keys are keys that have an RFID (Radio Frequency Identification) chip inside the head of the key. These types of keys have become an industry standard for vehicle manufacturers. This is because the RFID chip adds an extra layer of security to your vehicle’s ignition. When a key is inserted into the ignition of a car with an immobilizer system, the car verifies that the RFID chip is present in the key and is programmed to the car. The immobilizer system is what will stop the ignition from allowing the car to be started should a key not be recognized by the car.?”
像这样：
把老钥匙里面的东西都放进新钥匙后，用新钥匙打火，车子启动了但是马上熄火了，并且表盘上有钥匙灯闪，表明车子不认这个钥匙。应该是chip的原因。但是在老钥匙里找来找去也没有找到chip在哪里，坛友有没有建议？

然后用program tool加一个新的钥匙在车的电脑里。
一些middle level的scanner tool也带rekey功能。不然就去lock smith, 或dealer 做key program. 不过贵一些。
有的chip是做在key的塑料里面，看不到。如果不介意，就新旧钥匙拴在一起用就是了。如果能找到旧钥匙的chip,可以装到新的钥匙里。不过要注意装牢，可以用胶粘稳。看你的老钥匙像是Honda 车的。应该能在老钥看到那个chip。
Good luck.
如果是RFID，那应该有一个黑塑料可以拿出来的东西，像老金工给的资料里那样的，因为RFID里的chip靠感应电流工作，所以可以完全和车钥匙上金属部分分开。但是我车钥匙上没有找到类似的模块。
一个猜想就是俺的钥匙太老，不是用的RFID，而是老些的chip，和钥匙的金属部分连接，当启动时，通过金属部分的电流供电。如果这样的话就比较麻烦，因为只能买一个带transponder的新折叠式盒子，还要重新做programming。如果这么多后续工作还是算了吧。
如果chip需要破坏老壳取出，除非知道具体位置，还是有些不好下手。
自从前些年买的车有push start以后，再不愿意开需要掏口袋拧钥匙的车了，尽管另一辆车开起来一样舒服
手机用Bluetooth 和车对话，钥匙的不用。
bluetooth，phone都是中间阶段吧。开车门刷指纹，启动刷脸应该不难做到了。省的手机丢了麻烦。
我连老婆的电话号码都在手机里而不在脑袋里，信用卡号码，新车的VIN倒都记得。
