Aftermarket lock and starter-?

[JCJohnson]

I have an aftermarket starter and door lock security system, in the last month it has gone from not locking the doors anymore to also not starting the truck. It still sets the alarm. The truck's security system stopped locking the doors, then a week later the system stopped starting the truck. Help any ideas?

Opps! Probably posted in the wrong spot. Sorry!

I think when you have a problem with your driver side door lock sensor than the security system don't lock the door until you fix that. So check the door sensor to get rid from this problem.
