The symbols on my fob of my 2005 Ford Taurus beater got worn off so I ordered up a new shell for it from Amazon. It comes with the shell, rubber insert for the buttons, but not the electronics. I found it went together well but the car alarm button was too sensitive and would go off if it was lightly touched or even if the case was lightly squeezed. The solution was easy. With the case disassembled I took a sharp blade and sliced off the nub that corresponded to the alarm button. Now it takes a direct push to set off the car alarm. No more fake alarms. Enjoy.
