Fudman, that is an accurate description on what happens on my car: it gets progressively quieter. If you lock the car from the passenger side, you can still hear the chirp. If you lock it on the driver side, now you can barely hear it.
Any idea what "degrades"? I read somwhere that the alarm horn has an integrated battery. If so, can this be the cause? And if yes, can one replace that battery? Or you need to buy a new alarm horn?
The reason I want this, a loud alarm is helpful if someone tries to mess with your car.
