doors won't lock

[Viper5]

I don't even know what the point of the button inside is for. All it will do is effectively lock yourself in the car And then the led comes on which I don't know why either.

My 98 was doing almost the same thing for the last year the doors would not lock most of the time then quit working all together ,horn would beep twice like it was locking but locks did not lock , also the dash switch or the key did not lock it ,then I went to my local porsche dealer with it ,here it was the theft control unit module $409.96 ,remote for key $175 and key blade $125 plus $218 labor total $814
