Here is an interesting fact. Many years ago I installed the Radio Shack buzzer to have a tone when locking and unlocking the car. Recently I had to replace the factory alarm and we all know the updated alarm has the tone for locking and unlocking the car. So now my car has both. But they work opposite of each other. They tone at opposite times so it sounds like my car is playing a tune! I plan to remove the Radio Shack buzzer when time allows.
