Recently i took my car into bestbuy for a viper alarm installation. i got that and a proximity sensor. well the sensor works about half the time and goes off every time i open the garage.

Everything is installed but i just need to know if this is connected properly and if anyone has ever adjusted one before on how to do it. i spent about 2 hours trying to set it but i couldent get it to do anything at all. any help would be greatly appreciated!
