Alarm System

[ArSargE7]

About a year ago my truck’s alarm started acting up. Whenever I unlock the drivers door using my key the alarm goes off. If I unlock the passenger door with the key the alarm does not go off.

So every time I unlock the truck with my key, I must unlock the passenger door first. Then I have the option of opening the passenger door and unlocking all the doors with unlock button or walking around to the driver’s door and unlock it with the key.

Does anyone have an idea as to how to fix this?

dont use the power lock button to lock the doors then you wont set the alarm
or if you are using keyless entry transmitter to lock it also use that to unlock it
