delete valet button for added security?

I'm a noob installing a Clifford 330.3X in a 90 Honda Accord. This system has the valet button and flashing "system armed" LED combined into one unit so the valet button obviously is installed in a visible location. While researching how to install this alarm I came across an installer who said he always installed and programmed the system and then removed the valet button. He said access to the valet button is one possible path to a thief disarming the system. Removing the button removes the path. Does this make sense? Is there a benefit in doing this? I can easily install a LED only instead of the LED / Valet combo. Does this give me even the slightest increase in security? I doubt that I will ever have a valet park this car.

doing anything with the valet button requires the ignition to be used with it, whether it is programming or disarming the system. if the thief breaks the key cylinder to turn on ignition then the system can be disarmed through the valet switch. so, even if it is an all in one led/valet switch all you need to do to eliminate the valet switch component is to not plug it in to the brain, or add a secret toggle switch inline with the valet switch which will let you decide when the valet switch is able to be used at all. but keep in mind that this wont save you from a thief with as much time as he needs and a little bit of alarm knowledge at his disposal.

You need the valet button available if you lose or damage the transmitter, or if its battery fails. You'd use the ignition switch and valet button to disarm the system until you can get the remote fixed. Otherwise, you wouldn't be able to start the car and get home. However, there is something else you can do. First, test the two wires that connect to the valet button. One should be steady ground, and the other a ground whenever you press the button. At least this is how most systems work, but again, always test. Then, find a switch in the car that makes a ground when you touch it. Rear defroster, power mirror wires, turn signal, you get the idea. Cut the wire from the valet switch, and connect it to your secret switch in the car. Now it's harder for the thief to figure out, and you still have the ability to use it. If you want to be even more clever, continue to install the non-functional Clifford LED/valet combo switch, or even find a regular valet button from an old alarm and mount it in the kick panel. Maybe the thief will waste time with the dummy switch instead of looking for the real one.

Thanks, these are very helpful replies. So the thief would break the lock cylinder and use the valet button to bypass the alarm. The way to defeat this is to put a hidden switch in-line with the valet button or rewire the valet button to an existing or hidden switch. And I need to keep the valet in case my remote batteries go dead or I break the remote. That it? Thanks!
