The Perodua Alza Alarm Buzzer and BRK Lock are aftermarket security components that can be added to the car's existing alarm system to provide additional protection against theft and unauthorized access.

The Alarm Buzzer is a loud siren or horn that is activated when the car's alarm system is triggered. It is designed to attract attention and scare off potential thieves, alerting the driver and nearby individuals to the presence of an intruder.

The BRK Lock is a locking mechanism that can be added to the car's existing door locks to provide an additional layer of security. When activated, the BRK Lock prevents the car doors from being opened, even if the intruder manages to bypass the car's alarm system. This can help to prevent unauthorized access to the car and theft of its contents.
