How does the security system work?
If your Accord has a security system as a standard feature (all but LX models), you have built in anti-theft protection. The system is designed to flash the lights and honk the horn if someone tries to enter the vehicle without the correctly programmed key.
To set the alarm, just:
A. The key (from the outside)
B. The remote (from the outside)
C. The driver side manual lock tab
D. The master door lock switch on the driver’s door
To deactivate the alarm, just use the remote or the key to unlock the vehicle. If the system has been activated and you need to deactivate it, use the remote or key to unlock the driver side door.
The trunk can be opened with the remote even if the alarm is set. However, opening the trunk in any other way will set off the alarm.
Note that the security system will not arm if any door is not fully shut or if the trunk lid is not completely closed and latched.
