Some car alarms have a valet mode allowing you to silence the alarm so a valet can park your car, or the service department can work on it. It also silences the noise you make when you unlock or lock the car with a keyless remote.
Your playa neighbors don’t want to hear your car chirp, beep, or squawk every time you get something out of it. Take some time to learn if your car alarm has a valet mode. If it does, learn how to use it.
