i have a dei hornet remote and it doesnt have a screw in the back so to use it i always have to pinch the thing and hold it and push the button 40 times till it finally unlocks my doors. i looked for a screw to fit it at a hardware store and had no luck. do i just need a new remote or could i just find a new screw. btw the light will flash 40 times and still not engage the locks.
