How to set up the horn sound when locking the 10th generation Accord?

[RobertRose]

The 10th generation Accord does not have the feature of sounding the horn when locking the car by default, unless it is installed additionally at a 4S shop. After locking the car, pressing the lock button on the smart key twice in a row will trigger the horn sound. Below is some relevant information: 1. The 10th generation Accord does not have an automatic locking feature by default. To have this function, you need to visit a Honda 4S shop to update the program. 2. Some cars have certain features hidden by the manufacturer at the time of production to differentiate between high, mid, and low-end models. Owners can activate these hidden functions by updating the program themselves. If you prefer not to update the program, you can install a device that plugs into the car's OBD interface. Once installed, the 10th generation Accord can achieve the automatic locking function.
