My alarm does not stay after I lock the doors more than two hours, n now I can get my trunk to close n lock

try disconnecting your battery it sounds like a glitch and needs a restart. To reset the system just disconnect eh battery for 15-30 minutes and then plug it back on. Im not sure your modal has this switch but you can also try this. Look on your drivers side pillar where your seat belt is attached Behind the belt closer to the floor is a button on the pillar press it for 3 seconds or till the light on your door goes out and lock it. This is a manual shutoff of the cars motion sensors. commonly the sensors break down over the years and end up making your car go loopy i have to do this every time i lock my own car because of it or my alarm will just randomly go off on its own randomly.

Replace Accessory Battery, It is just fixed the same problem on mine. This car has two batteries: one starts the car, the other one maintains all the accessories working while ignition is off.

accessory battery is in the drivers side compartment , in trunk .
