Can worn door striker drain battery

this could be the door striker plastic has broken off this is the post sticking out of the frame when you close the door the lock closes around the striker to keep the door closed this striker could also have moved slightly from opening/closing the door thousands of times try this open your windows get out close all doors set the alarm wait a minute then try to lightly move the door/s in and out by grabbing the door at the rear part where the door locks to the frame where the striker is if it has any play in it the connection will break and this will make the alarm think the door has opened and the alarm will sound getting the door to close tighter will stop it from happening this is also true for the trunk if you press down on the trunk or your able to pull up on it a little the same thing will happen its loose and will trigger the alarm if this is not the problem I would then go to the door pin switches that turn the lights on/off when the door is opened/closed especially if the alarm was aftermarket installed but you can be sure the alarm thinks that something is opened and the door/trunk/hood are the only places that they are

Hmmm... If like other cars, you would normally adjust the striker post on the B-pillar.
Unless the hinge pins are worn, in which case the door would drop, and need lifting as you closed it, to allow the lock to align. The pins are usually replacable.

i would weld the metal add a plate behind the striker you may need to remove a washer and weld that to stronger medal outside the cracked area

dealers only

You should be able to remove the trimpanel on the lift-gate. then at the location of the striker in the middle-bottom of lift-gate you should be able to access a rod. Grab the rod with pliers, if pliers won,t fit the rod connects to a metal lever attached to the striker assembly, pry the lever away from the striker and this should release you gate....Good Luck!!!

It unscrews counter clockwise. More common is the metal around the area fatigues and needs to be built up...

Please inspect the door, lift the door up and down From the further most point of the door jam and see if the door pins are worn out. After that you can inspect the condition of the door latch assembly and the door striker (See if it is loose and/or if the sheet metal around the striker, is cracked or broken. You should find it soon enough.

The latch in the door is in the closed possition most likley or the latch is broken all together. Hold the door open pull on the handle. use a screw driver to unlatch the closed catch. it looks like a sideways w that closes in on itself around the striker on the door.

no prob you can do it

El nombre in Ingles es "Striker Plate"
